Just in case you want to know why they charge so much money at dealership. This is my engine being worked on for blown head gaskets. Notice the amount of carbon build up. There was a 2002 being worked on same time, it had about 1/4 inch build up.

See Attached images.

Do you have "full size" versions of those pictures? i'd like a copy if you'd be willing to email them too me. i can send you my email address.

is the last picture in that strip the one with the actual head gasket damage and carbon build up, or is it the 2nd to last one? I'm going to guess that the last picture with the 4 "circles" is one half set of the piston heads?

I've only see the guts of an engine a few times, so please forgive my lack of recognition... if so is the 2nd to last picture part of the 32 Valves we havew?

Thanks!

How many miles were on the engine when these were taken? Are there any other pictures? I haven't looked terribly close yet, but so far I don't see where the breached gasket was.

I sent you private message, you can include email address there if you want.

Car had 79,000 miles at the time. Noticed coolant loss again, just 6 months later, followed by increase engine temps to 250 degrees in 10th month 16,000 miles later. Currently using Thermagasket to patch it up with success at 400 miles.

As far as seeing the actual gasket, I was not there when they took the heads off, so never saw it. I am told there is usually a path on the heads or block showing the signs. I think you have to be an expert to see them. Maybe on close up image it will be easier to see?

This is the picture of the other head, not in previous images. You should be able to click on image and blow picture up? I am limited on image sizing for posting, so had to reduce these down by half size.

i sent you a PM back with my email address. when i click on those images they are look to be 600x400 pixels. not quite big enough. but better than the thumbnail.

I've seen several. The ones I saw would be very hard to find in a pic. They weren't blown apart. You could see where they weren't sealing well. It would take a close up I think.

are you having other work done on the engine? I don't see thew reason behind removing the entire drivetrain to change head gaskets. It's done on this board allt he time to put in the timeserts, etc.. removing the engine.. THAT is why the stealership is charging you so much money.. and any shop should be showing you exactly where the parts failed and why.. otherwise, they are bull$hitting you and taking your money.. my car is loosing coolant on a regular basis.. but it's because of the tiny crack in the POS radiator cadillac made for these cars. If you had coolant leaking into a cyllinder, that cylinder would be nice and shiny with no deposits of carbon.. or at least a MASSIVELY less amount of carbon than the rest of the cylinders.. if you had coolant leaking into the crank case and getting into the oil, your oil would look like a chocolate milkshake.. since neither of these conditions looks visible on your car, then you must have a gasket leak where the coolant would leak onto the ground.. If you were getting a puddle ont he ground, then you're set.. 9 out of 10 times, these leaks can be fixed with one of the many cooling system stop-leak additives. If you've had none of these conditions, you got screwed.. Or your coolant is leaking from somewhere else and they just wanted to hit you up for a motor removal and new head gaskets..


and for GOD'S sake man!!.. FLOG that poor car once in a while will ya??? That will keep the carbon to a bare minimum.. That's just WAAAAY too much carbon in an engine.. you're lucky you're not having other problems like stuck valves or valves not closing all the way from the carbon stuck under the seats. Your piston rings are probably caked up pretty good too.. Here's another free tip from you're uncle Jamie... If you find another decent warm day, pull the air intake hose off the throttle body and get yourself a good spray bottle filled with water.. start the motor and rev it to about 2,000 rpm.. then start spraying water in the throttle body.. this will effectivly "steam clean" the innards of your engine.. ask any OLD school car guy about this trick.. I do this at least twice a year along with frequent drag strip runs on the summer weekends.. I have a friend who's a mechanic with a bore scope.. we pulled the plugs on my car last summer and took a peak inside.. for 106,000 miles and original plugs, she's pretty darn clean inside.

But seriously.. you've GOTTA excercise that car once in a while.. hit it getting on the freeway or something... just give her a good ole leg stretching...

Please see this thread regarding carbon buildup int he northstar motor.. VERY good advice..

These are 11 month old pictures of when the dealership did the head gaskets. 10 months later they are blown again! This time I am using ThermaGasket from rxauto.com to fix it. So far good. Not sure I want to risk doing wide open throttles with the thermagasket in there. Wondering what the water in throttle body would do to the thermagasket?

I emailed you the pictures I had. By the way, tried to private message you on here but says, you box is full.

At what mileage did you purchase the vehicle. It looks like someone babied that thing for a while. That thing looked as bad as my 30 year old 455 when I went into it.

Thanks for posting the pics. I have a 94. It nice to see pics of another early model north*.

in the very last picture you poster is that the starter?? I alwasy wondered where is was located exactly That purple wire is what makes me think is the starter if you could Id appreciate if you could mark out in a full engine pic where the starters located, Im im the process of a starter change, I would appreciate and input or any help.

Yes, that is the starter. The red battery cable is attatched to the solenoid and the red shop rag is setting on top of the starter itself. It is located beneath the intake manifold, in the valley, on the rear (drivers) side of the engine.

Thanks Ranger, appreciate you answer that one about the starter. If I knew these pictures would help so much, I would have been more detailed.

By the way, its been a few weeks now with no coolant loss so far. ThermaGasket is holding up well.

Being a big anti "repair in a bottle" guy, I have to say I am surprised and impressed. I hope it passes the test of time for you.

I had a little scare today. After driving in holiday shopping, stop go traffic for 20 minutes hitting every stop light, and finally pulling into mall lot temp was at 220. I remembered last time that happened, and for some reason I revved the engine causing coolant to spill out overflow. This time however, I just watched it and temp went up to 225 fan kicked on and temp decreased back down to 212 so I shut it off. I just checked my coolant level again, and its exactly the same, no loss.

These Norstar engine temperature swings are not for the weak at heart!

Unfortunately I have not been able to do a mountain drive since adding coolant, but hope to do one soon. Either way, I am able to do highway driving and much local driving without any problems. Engine seems more sensitive now to the pedal, and I am reaching 4000+ rpms without trying. I never knew this engine to be so sensitive. Almost scarey.

Will post this in the Bars Leak section also. By the way, is there a way to change title of that post from Bars Leak, to ThermaGasket?

225 is when the fans come on - so I wouldn't get worried until it hits 225/227 and keeps on a trucking like mine did.

What a helpless feeling... at any speed, coasting at 45 and the temp continues to rise... rise.. RISE!! NOOOOOO :bighead:

My nightmare will be over soon...
