I"m trying to picup another Eldorado.

The one I'm currently looking at is a 98, and has an oil pan leak and rear main seal (so im told)

Its a few hundred miles from my home, and I'd kinda like you guys opinion as to whether this sounds right, and how tough it is to fix.

Thanks in advance!

Engine (drivetrain) out of the car, inverted, new GM RTV oil pan seal replacement, transmission removed, special rear main seal puller/installer. Not for the faint of heart. Probably new flexplate, too. TCC solenoid. ??? Halfcase reseal ???? - the halfcase is the lower half of the engine/main bearing stud girdle.

I do not intend on putting 2k into this car. I'm interested in buying it to re-sell it and make some $$.

True, I am looking for a 97+ETC but it has to be black on black w/sunroof.

I find one of those and I'd be willing to put that kind of time/money/work into it.

I was reading a few other threads on here that seem to imply that the oil pan (if the guy isnt lying to me) cam be removed from the car and resealed (no-one makes a pan gasket for it, must use RTV?)

It kinda sounds like I might need to pass on this one if I cant do the oil pan with it in the car....

And like I said, I havent even seen it yet, so knows what could REALLY be leaking.

No it doesn't use a gasket but an RTV sealant. If you can get the vehicle high enough to disconnect the y-pipe from both manifolds, and remove the cross under pipe maaaaybe. But I'm doubtful. I'd stick to the GM service manual, fix it the right way and yank out the engine..

What sub said, if you get it and decide to tackle the job, do a block test for HG, so if they're shot might as well fix that while resealing it
I'll prolly test for a bad h/g before I bring it home.... If it were the right car, I'd fix it. But since I'm just looking to start flipping with the hopes of building up $$$ to get the right one, I doubt I'll be pulling ANY engines that I dont have to.

The OEM oil pan "gasket" is a formed silicone "O-ring" that fits into a machined groove in the pan rail. The new replacement procedure calls for an RTV bead at the pan and halfcase flanges - discard the seal - both parts are engine structural pieces and a "gasket" will not allow the tight machine tolerances necessary. Blow up this picture to see the pan seal groove.

............ the halfcase seal and oil distribution manifold plate seals are also formed silicone knife-edge "O-rings"

I"m all about full disclosure, there is a certain subset of culture here that LOVES to get these cars for a cheap price and I can cater to "them"

If any car im looking to re-sell has major problems to begin with, im not buying it. i.e. h/g issues

So, you wouldnt use a new seal? You would just use rtv in the seal groove? I'm confused

The approved GM halfcase/oil pan reseal uses the new GM RTV Gray or Permatex UltraGrey instead of the formed seal. My post says that.

It MIGHT be in the Technical Service Bulletin section of AlldataDIY.

Thanks - and, FWIW, AJXTCMAN is still a (founding) CF member and is a working Cadillac dealership repair tech in NC. He also does ECM tuning work on the pre-1998 engine control modules. Much of his engine diagnosis work is rolled into the stickys in the Engines, Northstar Performance forum.

Hey Sub,

I keep asking, why can't I see the images?
