All it needs is head gaskets. No need to mill the heads or worry about anything else. I don't know where you are, but if you're near Ontario Canada, 97eldocoupe (Jake) will do it for $1500 with a 3 year, unlimited warranty I believe.

Find a mechanic that can install a set of studs and do the HGs.....

Or, do it yourself and save....

I'm working on a program on my laptop that will allow me to do a HG job over the internet.....:stirpot::histeric:

"I'm working on a program on my laptop that will allow me to do a HG job over the internet....."

Maybe just a step by step dvd... start to finish each bolt each wire include instruction on sealing the lower end, that woulda been amazing for my HG job and Im sure there would be others interested....

Just a thought...

Star Light I wish I were out there. I'd love to help you out.

What if you only had to drive 344 miles to Gaines County Texas to have it fixed with the studs and at least a 2 year/31,000 mile warranty?

Just a thought---- I might be able to set something up.

I believe most of us that have replaced the head gaskets have done no "hard" repairs to the engine other than to the block threads. No milling the heads, no grinding the valves, no replacing the cams or chains or pistons or bearings - we just re-assembled everything as-is, and the engines have lasted many more miles with no problems. In my case, I did replace the oil level sensor and rear main seal and oilpan gasket because they were leaking, but that was about it.

I think your original question was repair or replace - it depends on how long you want to keep the car and if you are willing to gamble.

well i bought a nwe long block from valve covers to pan and might part w/ the old one
whats it worth, (it a y 275hp motor from a 01 dhs w/ 120k blown head gaskets and leaky oil pan (i have new gasket witch come w/ it) the motor runs great when its not gettin hot.... the buy would be from pan to covers as is
if not intrested just let me no what its worth

IF YOU PLAN TO SCRAP THAT CAR.......give me a call !!!!!!

The newest Cadillac I've scrapped is a '97. Anything newer than that is worth too much to scrap. An '01? Fix it and sell it or fix it and drive it.

I think by saying this I'm agreeing with most of the posts here.

If it's only the HG job you need then there's no point in replacing the engine. If the oil pan is leaking and it's not the half-case then replace the pan gasket while it's out for HG work.

You'll end up in a good place with the original engine.

I don't think we know of any N* that actually needed an 'overhaul' so to speak, but if that were the case then I think I would have to say replace.

From what we know, aside from HG problems and oil leaks, I would say the N* is very reliable and is good for many miles if maintained properly.

If you have a use for it, it is worth keeping. Once it has the gaskets replaced and is Timeserted or studded, it should last a long, long time.

How much is the core charge? Go to www.car-part.com and price N* motors locally. You'll be surprised what they're worth. Do the math after that.

I'm tellin ya star light, fix your old engine. You'll be way ahead $$$ wise. $4600 for a cracked engine? Wow- I certainly hope that your warranty covers that.

its on the bottom crank case, they shiped out a new on today, but they said all blocks r presher tested b4 assembly, they think it might be damaged durring shipment, and they said they would reinburse me the labor on instail if it was not droped by macanic ect...
and ur right if u were closer u would have a sale, everyone i talk to says they want to put a low miles junk yard motor w/ no warranty 4 3k,
thats not a good deal, 4 350 core i wonder if mine is worth keeping, the labor factor is out of the equation now, and i could practice on it out of the car, but once i fix it what am i goin to do w/ it any ideas (maybe put it n a 60's bug w willy bars ha ha)

I did that - I replaced my original '97 engine with 89K miles on it with a blown HG with a used '97 engine with 69K on it - that engine blew the HG 23K later - better to fix rather than replace the engine IMHO. I paid $2,000 3 years ago for a used engine and trans (P0741 problem on my original), installed. I won't say it wasn't worth it, but if I had known the process the first time, I would have done the insert repair the first time, like I did the second time.

Get your money back and sell the car "as-is". Don't scrap it, it is worth something even with a motor needing HG's. That is what I did and to me it was worth the loss of $$$$$ just to get the junker out of my garage.

Hey Starlight,

I'm in the exact same situation you are in. HG blown on the 1997 STS I bought, and I have been quoted 2K to repair the heads and gaskets. however, with over 100K on the motor, I don't think I will be able to depend on the motor internals for another 70K or so.

Alas, I am going to spend the 3K for a new long block from Accurate Engine in Michigan, and have it installed locally. At least that's my plan. I have been reading countless stories about these HG failures and don't want it done and have something else go wrong.

Yes, I will sink another 2K into it, but better to have a sound engine and not nickel and dime me later.

Let me know how your story turns out..........will keep you posted on mine......Best, Heaven in 1997

N*'s go 250K without a problem (except HG's). These are not the engines of the 60's. Rebuilding one with 100K on it is a waste of money!

Sometimes I get tired of typing the same things multiple times ( I truly don't know how Ranger does it!) so I give short answers, especially when I'm in a hurry.

If the engine is running well with the exception of the HG's it will run the same way after you fix the HG's. New engines easily go 200K with reasonable oil changes.

If you have 100K on it it should be good for at least 100K more. :D
