Oil pan gasket leak!

Caddywak · #1 (**permalink**) 09-30-06, 10:46 PM

Hey guys, Northstar Noob here... I just purchased a 94 Deville and found that the oil pan is leaking at the gasket. It looks like a b@tch to get to, as the exhaust goes right under it. Does anyone know the procedure to removing the engine oil pan? Does the tranny have to come out? Does the engine have to come out in order for the tranny to come out?
How many hours work should it be??
Thanks guys!

The '94 Deville does not have a Northstar. It has a 4.9. Not sure it can be removed without removing the engine. try removiing one bolt at a time (the ones you can get to). Spray them and the holes down with Brakleen. Then blow out the holes and apply some permatex thread sealer to the bolts and torque to specs. That has been reported to slow it down drasically.

Hi! Thanks for the reply. My Caddy is a sedan deville concours, and it sure does have a northstar. Like I said, I'm a caddy newbie, so is there a deville and a sedan deville?

Anyway, if you think that removing the bolts one by one and applying sealant will work, I'll give it a shot!
Thanks!

Yes, on the Northstar engine, the motor has to come out to remove the oil pan. And the Sedan DeVille was just called Deville. The performance version was the DeVille Concours.

Ah, you didn't say it was a Concours. The base Deville did not get the Northstar til '96 or '97. I am not positive that the bolt sealant will work. It depends on exactly what is leaking, but others have reported at least slowing it down and for the price of pulling the engine to stop a niusance leak, it is certainly worth a try. Let us know if it helps.

You have your choice of A, pulling the motor, B, pulling the trans, or C, trying to seal it with some RTV and living with it if that doesn't work. I'd give C a try first.

You forgot D..... cutting the exhaust pipe, replacing the gasket, and welding the exaust back together.

Actually I tried that option, and it's not really viable. In fact it's a waste of time.

I'm going to go out on a limb here. On my 01 DTS I was looking at the oil pan the last time I changed the oil. It looked to me like it came right out with nothing in the way at all. Am I nuts? It's like oil pan on one side and trans on the other. Exhaust goes in between with the transaxle brace joining the two.

Oil pan goes over exhaust, where you can't get it out no matter what you try as long as that exhaust crossover is there.
