I have a 97 DeVille with 107400 original miles, which I know is not much compared to some of you. To figure out whether or not I can expect much more out of this engine, I would love to see how many of you have Northstars with higher mileage. If your engine is not the original, please let us know. Any major problems along the way would also be helpful, with mileages. I think that a thread like this could really help some of us anticipate problems and estimate the life of our engines!

Thanks,

From '97 to 2000, I had experience with Northstars. I had many in our fleet that had in excess of 200K miles but, sadly the majority were NOT original. As I recall, roughly half of the Northstar engines in those cars went by 150K miles and by the time I left, the highest mileage we had on a Northstar was about 220K miles. The usual problem was of course, head gaskets.

97 Eldo, 85k on her right now. But, 360+ miles a week is adding up fast, so give me time. At 150k, I plan to rebuild with high performance parts. Pistons, rods, heads, and that supercharger from XMS BETTER be ready by then. :) Hehehe

My 95 sls has 139k and is somewhere on the interstate in South Carolina with my wife and her girlfriends, on a shoppingtrip. It cruises EZ at 85 to 90 and can still light'm up when ever. Both my Caddy and i are still original. I have no complaints.

I plan on driving mine over 200k miles. I have not had a car not make it past 200K in 15 years. My cars seem to thrive on hard use. I am optimistic that this STS will go the distance.

If you are really "pimpin" with the 4.9L then you can very likely supply pictures with subjectmatter more interesting than dashboards, but since you ask, I will see what I can do. Is it the odometer you are interested in, or are you refering to the speedometer/tachometer readings.

I have a 93 Eldorado SC with an all original Northstar motor. It currently has 167K on it, and I expect to keep the car for at least another 2 years or so. It should easily have another 50K on it by that time. (especially because I love to drive this car any chance I get!) :D

One thing I was a little concerned about AFTER I bought this car this summer was oil consumption. I began reading all these complaints about this. I was extemely happy to find that mine uses only about 1/2 qt. between oil changes (about 4K miles), and I think that is due to seepage around the case seal and oil pan. Snugged up the bolts on the oil pan and it cut down the dripping quite a bit. Good luck with your 97 :devil: !

Not yet. They are still working on a s/c project, but it still isn't working 100% yet. I figure in the 2-3 yrs or so it'll take to get to 150k someone will have it done.

Hi Kevin,
Who keeps fleets of Cadillacs? Was it a rental fleet like Hertz or Enterprise? Was it a texas company called Enron? How many companies have fleets of Cadillacs?

Can you detail about the head gaskets? Was this a corrosion factor? Coolant factor? etc. What do you think was the preventive?

Well, I have a 1997 Seville STS with about 176,000 miles on it and the original engine and tranny are still kickin. I will provide a pic if you so desire. I have replaced the knock sensor, master cylinder fluid sensor, and it needs a new idler and tensioner pulley in the next 10,000 miles. This car runs like new, doesnt smoke, doesnt leak, doesnt burn ANY oil, and still pulls a 14.8 in the quarter. I need to replace the struts/springs, rotors, and pads soon. All parts that are wear items have been replaced when necessary.

Makes me proud to be a Caddy owner. Doesnt it?

now leaks a little oil (began around 100k)We bought a 97 with 41k and it has now turned 121, I am told I have a blown head gasket or a cracked head or block and should get a new motor. It blows coolant out the overflow, but doesn't register hot, with normal around-town driving. It's very disappointing, the car is wonderful to drive.

I have a 94 eldorado with the 4.6 northstar that has 132,000 miles. I am running into the first problem with it so far. It is some kind of electrical problem and may have nothing to do with the engine. I hope I can figure out what the problem is. I have had the car for 7 years.

25,550 on a 2000 DHS. Purrs.

The 4 year warranty ran out yesterday and I am gambling that not buying an extended warranty is the way to go.

Encouraging to see the above numbers.

12-12-03, 05:35 PM
Thats great...... Personally Id get another warranty.... I know that it would be hard to believe that your DHS wouldnt be running perfect, but Id still do it....

Hopefully the newer cadillacs will have a better record for reliability than did the older ones!

95' STS N*, 180K+ miles(As I recall it's very close to 190k), runs great with Nitrous too. Replaced almost everything AROUND the motor, including new tranny(This was when I first got the car) but the engine has been fine, no maintanence required, regular 4000 mile oil change intervals with synthetic(I know I could change with longer intervals, but rather play it safe).

I saw a 1947 Kenworth truck in 1961 that had 3,500,000 miles on it, nearly all on the Alaska Highway. It averaged almost 700 miles a day on the road and belonged to Lynden Transfer of Washington state. The last I saw of it, it was still going strong.

I've got a 95 SLS w/ 136K on it. No real problems in the beginning except a wicked oil leak from the oil pan and manifold, something to the tune of 2 qt's a week. But so far I've gone from just replacing the oil pan seal and manifold to having a stripped main bearing bolt hole. I'm in the process of timeserting the block (got 3 holes done last night) and will have to install a new set of rod bearings. Overall the engine looks to be in excellent shape. I'm sure in the next 100K i'll have to do the head gaskets.

I am now seeing 144 k on my 95 SLS and outside of minor oil leak, it is still very strong. When placed in D2 trans position the line pressure bilds and it leaves like a racecar. Solid shifting I grad 3rd at 6200 and it runs well. I have been told that that change in tranny line pressue and lockup is for towing purposes. Love it for barkin tires.

We had about 250 vehicles all together (approx. 230 were Cadillacs), and that was enough to make us the 3rd largest limousine fleet in the country and the #1 largest all-Cadillac fleet, PERIOD.

Posted this same reply on another thread, but here goes. I have been away from home for over a year, but last check my '95 STS has approximately 225,000 miles on the original,untouched engine and tranny. Change oil every 3K and add a quart every 1K. Don't even use the much talked about coolant pills. My wife drives it about 50 miles round trip to work everyday and averages over 20 MPG on every tank. I'll be home from Iraq in the spring to see how well the wife has taken care of it.

We often saw 250K-300K on 4.5 Devilles in a taxi fleet in Pittsburgh that GM susidized with the Cadillacs to use for field fleet experience.

Lots of the executive limo services in the metro areas use the 2000 style Deville. We have seen several of the Metro cars in the Detroit area with over 200 on them.

There was a certain 93 Allante in a GM development fleet that was flogged religiously by everyone that drove it. It was torn down at 130K and the engine looked great inside... Seems like the harder the engines are run the better they look at teardown in my experience. That is why I am such a firm believer in occasional WOT operation...very occasional.

Lots of our "in use" fleet cars went over 100K in general driving conditions and tested pre the FTP for emissions and were fine. This fleet proved that oil consumption does not affect the cat significantly as per conventional wisdom suggested it would.

My Yamaha XS1100 motorcycle (circa 1978) is sitting in the basement in semi-retirement with 108,000 miles on it....LOL. It has been to Alaska twice and to Newfoundland and in just about every state and province and it still gets ridden every year just as a matter of tradition. It actually runs great and has no problems at all except from sitting too much. Original engine and such. Lots of maintenance on it but that is all.

Some of my favorite all time "mileage champs" spend their entire lives in a dark room running at heavy throttle and 3600 RPM for years.... It is not uncommon for large office buildings/small skyscrapers to use automotive engines running on natural gas to power the compressors for the commercial AC systems for the building. In the Detroit area I have seen several installs like this that the gas company actually pays for the equipment just to sell the building the natural gas to run the engines. They make a very cost effective means of powering the huge compressors needed for large building wide AC systems. It is either that or electric motors and the deciding factor is the cost of electricity vs. the cost of the natural gas. Those engines, converted to natural gas, will run for thousands and thousands of hours under moderately heavy load like that. They are almost universally big block chevy truck engines that are converted and installed. Many of them run for decades with little or no maintenance other than lube oil changes.

Mine's a '97 STS with 117,000 miles on it. Have only had it since 110,800 miles. After buying it, I replaced the AC compressor and had the fuel injection treatment done. The car runs like a raped ape, but the engine has a mild ticking noise. The engine does drink a little oil since I have to add some every couple weeks, and there is no evidence of a leak anywhere. All said I love this car and will definately buy another Cadillac when this one has worn out (several years from now I hope):D

94' STS 168,000 miles, no interior engine work work whatsoever, solenoids in tranny @ 150,000. Still runs like a bear, 200,000 + should be no problem. I had an 88' DeVille that went to 275,000. Steering, suspension & interior all took a dump, but the 4.5 engine / tranny still ran well! Only major on the 88' was intake manifold gaskets!

I have a 97 DeVille with 107400 original miles, which I know is not much compared to some of you. To figure out whether or not I can expect much more out of this engine, I would love to see how many of you have Northstars with higher mileage. If your engine is not the original, please let us know. Any major problems along the way would also be helpful, with mileages.

I have a 96 Concourse with 190K miles. It started burning an excessive amount of oil at about 150. My owners manual specifically advises against using 20W50 oil. I switched to 20W50 and it stopped burning oil. This exact same thing happened with an '85 Seville that I previously owned. It started running really badly at about 180K, so I took it into a dealer for a checkup. The shop told me that my only option was to take it to a junk yard. I changed the spark plugs myself and all the problems disappeared immediately. Now it runs like new. Every dealer I have been to since the car got 50,001 miles on it have treated me like a piece of shit. I started burning regular gas 50K miles ago with no ill effects. The brake warning, traction warning, engine warning lights and the tgransmission warning message have been on since about 50K miles, with no ill effect. They simply cannot be turned off. One Cadillac sholp told me there was nothing wrong but it would cost $2500 to get them turned off. I plan to find the biggest, poorest, largest welfare family that I can and give the car to them when I get ready for another car.

My 94 SLS has 125,+++ with a minor oil leak

and I know it is not a caddy, but my Jeep XJ has 194,802
and both have original engine and tranny. and I beat my XJ hard in mud and rock climbing
Oh the caddy runs strong and can be on the highway. loves to hit the tripple digit zone on speed, only when no one else on the road.

I have a 94 STS, 116k miles not many miles compared to some, but it runs great, I had to replace tranny solenoids and the alternator, oil changes by the oil life meter and it looks great, people are surprised when I say it is a 94.

On a different note, my wifes 92 Buick Lesabre just turned over 188k runs like a champ, no major problems with it other than normal maintenance and 2 alternators.

I have a 95 etc 89k miles no leaks runs like new. I used to work for a local cadillac dealer and I do know the northstars are known for head bolts (stripping and leaking) and also the mid case leaking oil. If this has been fixed on your car they run fine 200k miles plus :thumbsup: I have seen a mid case leak at 30k and also at 100k so I guess its just what day the car was built on or if the guy building the motor was pissed at his boss that day :farting:

(...have seen a mid case leak at 30k and also at 100k)

The case halves on my STS were leaking at 40k miles! The ones on my old '94 Concours didn't leak until after 100k.

My 95 ETC is at 104K after my trip... put around 2500 on in the last 1 1/2 weeks. Figure I'll change the coolant and tranny fluid since it's telling me to.

My first Seville, a 1984, ran for over 300,000 miles (no kiddin'!) -- the water pump blew on me and warped a head gasket, thus, she died. I just bought a 1997 SLS with over 130,000 miles -- original Northstar engine -- and he runs beautifully. A slight oil leak from the oil pan gasket -- not unusual for Caddys -- is the only "problem." I never mind gasket leaks as it keeps the bottom of a car rust-free and well-lubed.

I have a 1994 SLS Diamond white -- in premium shape -- with+126,000. Outside of a little problem with an occassional surge at a traffic light I am pleased beyond words. As is common I need to add a quart of oil between oil changes. The engine, as far as I am concerned is still outstanding. :)

Old thread I know but I just wanna add the my 1993 seville STS has 196*** and it does not leak any oil. I add one quart of oil between changes (every 3000). No problems yet and is it ever strong, you can feel it when you go WOT. I am very impressed with the car, only had about a year. Hope my northstar continues strong into the future.

02-21-05, 07:53 PM
My STS has 108,843 miles right now on it. No oil leaks but burns a little when accelerating hard. Replaced the starter, intake manifold gasket, and the battery. We had a 87 Astro van that went to 315,400 before some jerk attempted to pass when we were making a left hand turn and caved in the driver's door. Insurance company totaled it. It would have been interesting to see how far it would have gone.

I have a 94 SLS that went 259,000 before it spun a bearing,not a head gasket. I am on my second motor with same tranny @ 301,000. It has been a very good car. I attribute it to changing the oil at 3,000 and alot of highway miles. My 2003 Deville is junk. I just sold it at 50,000 with many problems. I will buy another though,if I can talk my wife out of the Jaguar. If any of you are wondering why your 93-96 sls-sts has water in the spare tire area,you sun roof is leaking. It has a drain hose to the trunk. Took a while to figure that out.

I left Florida moving to Tulsa,OK at 120K in my STS had only changed the water pump. mid route in Birmingham, AL My Heads went south on me...COULDN"T find a mech. that was WILLING to do the Heads there....LOL :confused: ended up buying a used motor with 94k on it and kept on trunkin' another 14 hrs strait no problems...runs better that it did at first. had to put another water pump on it though. (they didn't keep the one I had just put on there)...since then I have put another 15K on it and now I need to change my Soleniods in the tranny. other than that looks and runs like new...(until i get up to about 55mph)...lol but that will soon be fixed...great thread..:thumbsup:

My 1994 STS has just over 24,000 miles. Oops, I'm looking for the low mileage thread. Seriously, your posts about high mileage give me lots of confidence in the the car in general and the N* in particular. Gave it some WOTs today. I've read the threads on whether or not the WOTs are a necessity or just for fun. Can something that feels and sounds so good also be good for me? Better not get too philosophical and take all of the fun out of it.

I have 245000 miles on my '93 ETC... Orig engine and tranny.. Replace H2O pump twice, Alt twice (because of knight rider lights in grill draining battery), 2 Coils (the #1/#4) One Radiator, 2 O2 sensors, 2 catalytic converts, 2 tranny solenoids (both at same time), one fuel pump, A/C compressor and most recent harmonic balancer replacement.. (Numerous tires, and front head light bulbs, plug wires, spark plugs only 3 times) Now plastic around the firewall is starting to break/flake apart.. Started running synthetic oil at 84,000 and I contribute it to saving the engine during the H2O pump issues... All this and I'm still not afraid to take it up against anybody that once to race...


I need to replace the struts, they went out at 100000 miles but I keep putting it off and I have to go to a junk yard for a wheel position sensor that acts up in the morning.. Hope I can find a good deal where the guy selling it doesn't know what it is..

I have a '95 Eldorado with ~145K on it. Highway mileage is 29-31, and overall runs about 22-23. The engine has had very little work done to it (maintenance only), and so I consider this to be "broken in" mileage.

Hands down it beats my 2004 SRX for mileage, comfort, kick-you-back-into-the-seat, fun-to-drive, and cruising range. I'm glad I kept the Eldo when I got the SRX, and I will undoubtedly have the Eldo long after the SRX lease ends (and I don't get another one).

I have read this whole thread and I seen the numerous years of different Cadillac with high miles, which is excellent! But I did not see one person post about a 97 SLS with high miles. I would think there would be someone out there with a high mileage 97 SLS. Mine has only 68000 miles and so far I have changed the Water pump belt and the Tensioner and the FPR. I just love this car!

I should ask Alan Johnson of CHRF if he saw the cause of the spun rod, after giving him the old engine.

what did you do?
TOTALLY flushed the coolant system...I MEAN TOTALLY! (if you don't, you'll have a reaction with the block seal stuff that will clog your radiator). Then, added the block seal and toped off with water. Run this way hard for minimum 500mi. (make sure you're in an above-freezing climate durring this time). You can leave it in as long as you wish. After 500mi., drain, flush, rinse, repeat and then put your coolent in. You should get another few years out of it. I read it on the internet ( I think "The Honest Mechanic") and it works.

I only have 94,500 on my 98 Deville right now; it had 91,500 when I got it. But the lady who owned it before me (who is now 80, but was the only owner of my car) was very savvy....she dealership serviced the car, and I was digging through the service records the other day and got a new lease on life! Just before her factory warranty was about to go out, she complained about oil consumption issues and somehow convinced the dealer to re-seal the entire engine! On the invoice, you can see all sorts of gaskets, sealants, etc. listed under the "parts "category. It took them DAYS to complete the repair. I dont know how she convinced them to do that but she did, so I have a good shot at making it far in this car as far as oil problems go.

Damn thats really awesome. You should be able to take that Deville quite a long way.

I had similar luck when I got my '00 Seville w/54k miles. The previous owner had the car dealer maintained, and right before she traded it problems started arising with hard starting and stalling. Headgasket was blown, and a few other things were wrong with it. When it was all fixed up, I bought it. I have a long way to go to catch up to you guys. :D

97 SLS with 165,xxx. I bought it with 121k and have had lots of small issues. First to go were the wires in the ignition that contact the resistor pellet in the key that kept making me wait 3 minutes to start the car. Had a bad front left hub and I think the front right is going too. Had "Engine Misfire" due to a clogged fuel injector, but I changed the plugs, wires, cleaned the EGR valve and checked the solenoids tracking down that problem. A/C had a bad o-ring that I had to replace, then evacuate the system, then fill with refrigerant. Muffler rusted out and got very loud so I had to replace that. Regulator on the alternator blew out around 130k. Driver's window switch broke with the window down (of course) so I had to get a new one from the junkyard. Now the power antenna is stuck up, but I can replace that whenever. Oil consumption is about 1 qt every 600 miles, but other than that (I'm sure I'm forgetting a couple things), she's running great!!

Seems like I've got a used car with a bunch of new parts. Hopefully it'll hold together for another year or two until I can get something else.

98 concours. Other than the norms; alt, wp, just changed water pump crossover gaskets. NOT FUN! I have a cold tranny whine and little slippage at frist start up. With 213000 everything else is orginal and I love the car. Went to passive shocks a few years ago and never looked back. The car is pearl white and STILL turns heads!

i just bought a 01 Deville with 203,000 and change as a beater while i worked on my audi tt, but in the last couple of days the car has grown on me and ill be fixing it up too eventually, im thinking about dropping a new engine in it since it has the all time famous head gasket issue:rolleyes: and i dont know if the heads are damaged or not but the car runs pretty good i think, it's the first time ever in a caddy :-). this is my first post too :highfive:

Hey everyone. This is my first post here. I am not a Cadillac owner(yet), but I came here looking for some advice. I am in the market for a DTS. I have found one at a local Cadillac dealership for $4999. It is a 2003 with 182,000 and some change. The price is affordable and the pictures look ok from what I can tell(no torn up interior, exterior doesn't look like its obviously been hit and patched back together, etc). I am a bit nervous about buying one with that many miles on it. That's over 30,000 miles a year and I don't know how well the previous owner took care of it. Any questions, comments or advice would be appreciated. Thanks.

312000 miles on a 97 STS. Everything still original with the engine, of course the spark plugs have been changed 3 times, new wires once, new coils once, new alternator once, new water pump once, new fuel pump once and now needs another one, new fuel pressure regulator once, new rear knuckles on both sides, new aluminum heater core(the original had plastic tanks that split and filled up the floor board with coolant...not to mention it looked like Cheech and Chong was driving with all of the steam/smoke coming out of the windows). The dirver window and the passenger rear window doesn't roll down, all 4 struts are bad, she uses and leaks a little oil (to the tune of about a quart/1000 miles. The air dam on the front has been ripped off from running over one too many jackrabbits. Other than that...she's cherry, no dings, dents or scratches and...if a new fuel pump was installed, she would still run like a striped assed ape! Oh yeah, she's still getting 22-24 mpg! Has been a good car!

If the vehicle is as nice as you describe, it would suggest to me that it was one of two things.

1. A limo service vehicle - this is OK. Most limo companies service their cars on a maintenance schedule religiously & if it was highway miles, then it is probably a more solid feeling/running, first private owner or company car as opposed to multiple "city driving" owners.

2. A privately owned car that was used for long distance commute. Possibly a salesman's car? In this case it was probably on a more rigorous maintenance schedule as well.

Check with your local Cadillac dealer. They might be able to give you some insight into the service history if it was brought to a dealer for warranty work, routine maintenance, or otherwise.

MrPibb, Northstar engines are tough engines. If mistreated they can be destroyed like any other engine, but as long as the oil maintenance was kept up, and hopefully the cooling system as well, I'd say go for it. Take it for a test run and make sure the temp guage stays on the 12 o'clock mark (creeping up slightly above is OK as long as it comes back down right away) and that it shifts smoothly. Check the oil for cleanliness and open the oil cap and take a peek in there as well at the heads. If it looks good and clean (aluminum color or slightly goldish/yellow) then the oil's been changed fairly regularly. If it's dark or black like tar, stay away from that Northstar. The first place oil builds up and turns to sludge in a N* is in the ports behind the chain tensioners. But I've seen N*'s with over 200,000 miles (359,000 kilometers to be exact) in great condition on the factory build- burning no more oil than what you'd expect for a N*, and no knocks or funny sounds. The lower timing chain tensioner is the first to wear out, but some last longer than others- depends on the amount of splash oiling. That's something we all take a chance on. The chains last damn near forever. The intermediate cam sprocket and mount can wear out too, but again that depends on oil and maintenance.

Also, check for irregular noises and knocks as usual. cv joints and wheel bearings should be on the repair list for a car with that amount of miles- if they haven't been recently done. If you go to the right places, these parts won't hit the wallet too badly.

Had a 95 STS that was still running on original engine at about 285000, but we got rid of it and I don't know how it is doing now.

Still have a 2000 DHS with 270000 miles, has broken a couple of engine mounts and front cylinder head was rubbing 1/2 way through the upper radiator hose. Orig engine and trans and neither has ever been opened up. Cracked the radiator last out of town trip and hopefully after rebuilding the cooling system (new thermostat, pump, belts, tensioners, crossover gaskets, radiator, surge tank, and hoses, all of which are original!) and new motor mounts will continue to serve me for another 100000 +.

I have a 97 Eldo ETC with 124k on it. Its been well maintained but it has been driven HARD HARD HARD. Somewhere around 200-300 launches EASY. There hasn't been many times that its been driven that it hasn't been WOT'ed at least once since about 60K miles (only when tight on gas money). Engine still runs the same as it did at 60K but the trans is on its way out the door. slips and whines and doesn't like to shift.

I'm looking at a 1996 Deville, has 125k miles, the guys says it needs a lower ball joint on the front left and a hub bearing on the same side. And that to have both replaced would cost about $500. Is this accurate? Would I get that done at a dealership, or a independent place?

thanks!

I'm now closing in on 71k miles on my '00 STS and the only real engine problem I suffered was the all too common crankshaft position sensors, which I got fixed back in January. Otherwise my motor has been great; it had the HG's replaced, Timeserted, resealed, etc. back in June '08 at 54306 miles. It also had the coolant crossover done (seems common on '00+ Northstar). My only complaint is my slight "miss", which has been narrowed down to my camshafts. Personally I think it's a small vacuum leak because when I powerwash my engine it always misfires. It still runs like a bat outta hell though... :sneaky:

I have a 2000 STS with 362,000 km and still working fine. I love it. It was getting a little sluggish so I replaced the fuel filter and got back the 100 hp it was missing. Hey ryannel2003, you mentioned about having the HG's replaced, Timeserted, resealed, could you explain, thanks. I am looking at a '96 Eldorado, only driven in one winter, 129,000 km, spotless top and bottom. Asking $4,300. I am just worried about head gaskets, would anyone like to give me there thoughts on what percentage of these Northstars do blow gaskets. I heard the 2000 + have used larger head bolts so they don't pull in the aluminum blocks and release the gaskets. My brother has a '99 STS and had his blown. :helpless:

ryannel2003
06-04-09, 10:00 AM
The car had been having issues with Low Coolant messages, throwing a few codes, and had been generally running poorly. At this time I didn't own the car so the first owner traded it in on a newer '08 STS and when I had inquired about buying the car they said it had some motor trouble. I personally think the HG didn't need replacing because the car did not show any obvious signs of HG issues (using coolant, white smoke, etc.). The coolant crossover did have to be done so I figured the dealer went ahead and did the HG just to be on the safe side of things. They also did a reseal on the bottom end and a rear main seal (even though the car didn't leak any oil) again, because that is another common Northstar complaint.

There really isn't a number out there that could rationalize how many Northstars have had issues. Some have problems from the beginning, some don't ever have a problem. I don't think the '96's were as prone to this failure as the '97-'99's were and I'm not sure why. It could be something to do with coolant, it could be the design.

06-04-09, 10:36 AM
Well, I bought a 1997 Seville STS with about 84.5k miles on it, I've put almost a thousand miles on it in two weeks lol. What can I say it's fun to drive. No major issues yet, it had a "Service ride control" message but a GM dealer fixed that, it was just a disconnected sensor. Also said 'check coolant' but I added some dexcool and no problems since. The dealer checked the car over completely, and said it's in great shape. All I have paid for is to have the rear rotors machined (certainly not the car's fault) and for the labor of doing the checkup, oil change, and fixing that ride control sensor. Hope I can catch up to you guys and still be driving this car at 200k!

I have a 97 DeVille with 107400 original miles, which I know is not much compared to some of you. To figure out whether or not I can expect much more out of this engine, I would love to see how many of you have Northstars with higher mileage. If your engine is not the original, please let us know. Any major problems along the way would also be helpful, with mileages. I think that a thread like this could really help some of us anticipate problems and estimate the life of our engines!

Thanks,
Jim

My entry:
107400 miles original
no known major problems
now leaks a little oil (began around 100k)

My '93 STS has some of the 'unlucky' engine problems like little oil leaks. I replaced the Northstar with a simular milage used one, even though I serviced much of the engine bay issues like the wiring harness, changed out as much of the gaskets /oil seals I could. The main problem ( besides the GM Manufacturer's DEFECT headgaskets that GM screwed everyone on, by IGNORING IT)

It's replacement parts!! Injector - plastic fittings & vacuum parts are not around anymore. Fortunatly, I have the entire spare injector assy & throttle body.
Unfortunatly, the fun is gone working on my car because I don't have the diagnostic tools.
I am selling mine, for a very nice '93 Mercedes 500 SL, that won't have a headgasket problem.

215000 miles. Running back and forth 101 San Jose - Santa Barbara (294 miles, 4h on the clock every week). 25 to 25.5 miles per gallons (all data from on board computer). A comfortable and secure car.
Engine ran fine until recently.
Oil consumption was 1/4 per 3000 miles, until recently where it developed a leak at the oil pan seal. It seems fixing this is really a pain, from the amount of work involved (pull the transmission out, and part of the exhaust), the problems it can create (it seems there are two gaskets above and below an intermediate plate right above the oil pan, and this plate seems to support cylinder sleeves, so i don't want to move it...) and the fact that I'm not the one that will do it ($$$).
The leak by itself does not bother me too much, but the smell when oil is projected on the exhaust is a problem, not talking about potential hazard (oil and a very very hot catalytic converter).
I tried "unclassified' mechanic: cleaning, degreasing, pull bolt one at a time, clean them, prep them, add sealant, torque back to 10 lb*ft, and add sealant all over the seal on the outside. Worked very well where I had access. But not where I can't access (over the exhaust).
Anyone with any experience of trying to cut the exhaust line and add one flange (before it goes back over the transmission) so no more need to take the transmission off to change the oil pan seal?
Thank you.

My 98 Deville has 165,000 miles on it. I bought it two months ago, and use it as a daily driver on a 100 mile roundtrip commute to work. This car runs great, lots of power.

I talked to the previous owner, and there has been no engine work done on it. He is one of those guys who keeps all the maintenance records, and keeps on top of the maintenance. It also was garage kept. He sold it because he just bought a 2006 Caddy.

A few other things have been replaced, such as the A/C compressor, but nothing engine related.

The 98 Deville is a great looking car. Much better than anything put out today, including the new cadillacs. Plus it gets 27 mpg. Thats pretty good considering it is a full size sedan (a real full size sedan means something different today than 11 years ago evidently - A current year Ford Taurus is not a full size sedan in my opinion). Why can't car companies make a car as good as the ones made 11 years ago?

As long as this baby runs, I have no plans to buy another car, even if it means I am driving it 10 years from now.:welcome:

I've got a 00 STS, 134,000 original miles. Only major work has been a radiator replacement about 2 months ago. I found paperwork that the tranny was rebuilt at about 105,000 but no HG problems to date (knock on wood). Interior is beautiful and the ride is nice and soft as well. My father-in-law just bought a 06 STS with about 19,000 on it and I wouldn't trade it in an even swap. The newer ones are a little stiffer it seems and the interior isn't on the same level as the Seville STS.

2000 Cadillac Seville SLS - 87,056mi and needs new head gaskets/bolts
1999 Cadillac Deville Base - 103,713mi and going strong. Coolant exchange due.

Nowhere close to high mileage but already have a damned head gasket. :(

Sorry to hear that! I wonder if you can ask Jake if anyone in town does the HG job with his stud kit. I have a good mechanic (in Plano) but I'm not sure he delves that deep, but he's open minded and honest.

102000 DHS 03.

Hey guys sorry but I haven't owned a northstar yet, but I do have a green 94 deville with the 4.9l engine, pushing about 231k and still running strong, with original trans and motor. I used towork as the quick oil change guy for walmart, and I've seen a lot of northstars come in with over 170k on them, even though they were the 96-99 models. I haven't seen that many 00 and up northstars with over 100k on them. I remember one 00 dts came in with over with over 260k miles on it, all original. The owner said his miles mostly came from commuting an hour to work and back 5 days a week. The northstar is a performance motor that is built to be driven hard, and designed for long trips instead of grandmas short .2 mile trips to church and the grocery store every few days. I commuted to work everyday, which is about 35 mins where I stay, and my miles are mostly highway. Maybe highway driving, along with proper maintenance is the key to keeping a northstar alive without the infamous head gasket problem?

I have a 97 DeVille with 107400 original miles, which I know is not much compared to some of you. To figure out whether or not I can expect much more out of this engine, I would love to see how many of you have Northstars with higher mileage. If your engine is not the original, please let us know. Any major problems along the way would also be helpful, with mileages. I think that a thread like this could really help some of us anticipate problems and estimate the life of our engines!

Thanks,
Jim

My entry:
107400 miles original

My 1999 Devill had 149,000km before the bolts let go. the guy who fixed mine has seen them as low as 60,000 km in his shop. It is not mileage it is the aluminum corosion and the threads are too thin and let go. The guy in Toronto has a 13 year old fix and it is great. He already used the coarse thread then and then the sure grip studs were created a few years ago. So the coarse thread idea was created by a machinist in Toronto not a few years ago like studs.
no known major problems
now leaks a little oil (began around 100k)mmmm

93 ETC original engine, 154941 and counting. I can sometimes smell oil and put in a half a quart after an 800 mile trip. From what I read so far leave well enough alone, but I would like to know what kind of job it is to replace the oil seals? My brothers a mechanic and we can pull her - take the engine out - if we have too. Love this car! Last work: Water pump, PCV, Front Oxygen Sensor, MAP Sensor, EGR Valve, Idle Speed Control Motor. She runs great.

1996 STS, all original, started loosing coolant at about 120K miles, HG failed at about 162K miles. Overheats after 15 min on the highway, 1/2 hr around town.

My 2001 Deville DTS has 137,000 miles on it, and it drives fine. And it's the orginal motor that I know of. I bought the car with 75,000 miles on it. I'm told though that the case halves are beginning to leak, which is a common problem of the Northstar engines. I'm told by my service advisor that as long as I keep an eye on the oil level it should be fine.

Currently I have 401,000 miles on the car...the tranny finally lost it's road gear(OD) at 377k..still original engine,head gaskets,starter,front drive axles(and boots),exhaust system(less the cat),rear wheel bearings and even the original headlamp bulbs(most of my driving is at night!)!! I will be eventually be posting pics of the car and the odometer when it hit the 400,000 mile mark. 1996 STS

WOW! Very impressive. You should send a copy of this to Carroll Custom Cadillacs. They say "All Northstar's will lose their head gaskets around 100k to 140k depending on how the car has been driven, sometimes sooner sometimes later".

I've been meaning to post here for quite sometime. First of all let me thank you all. This forum has been a wealth of knowledge and an inspiration. I have a '98 Deville that I bought in June of 2004. It had 73,000 miles on it and I paid $8,900 for it. On 11/16/11 my odometer rolled over 500,000mi. Original engine and transmission. Only thing that's been done is fluid and filter changes, plugs and wires. No electrical problems but as far as the rest of the mechanicals it would be easier to tell you what hasn't been replaced. Still original are the starter, master cylinder and power steering pump. I still drive it about 5,000 miles a month,in fact today it turned over 505,000 miles. It still likes WOT and I wouldn't be afraid to go get in it right now and take it across the country. Btw..it's only been to a dealership once since I've had it for a fuel pump. Again, thank you all, Jeff

I have a 97 STS with 198,xxx miles. Engine has never been rebuilt. have replaced lots of small issues tho. (Starter, Altenator, fuel pump, brake lines, the whole front suspension pretty much) still have issues that need attention such as a new A/C compressor and all that and i need the whole rear airbag suspension replaced and i need to replace the rear left hub on the car do to a wheel speed sensor code that is cuasing issues and tranny slips some. Other then all that the engine runs great, no coolant leaks and it burns a little oil which is expected on a N*

I did send an email to Cadillac customer support with the photo. They replied back wanting my phone #. She said congrats and asked for the VIN because they wanted to give me something. I was encouraged. Turned out to be a $100 gift certificate to the dealership of my choice. She did say my mail would be passed on. To who I don't know. Oh well on to 1,000,000..or 999,999 I suppose...
