Leaking oil Pan

[626CammedSS]

I have done my oil pan gasket twice already I never had a problem with the gasket leaking until I had to drop the pan when I replaced my pump and a few other stuff when I broke a lifter , anyways I had everything back together first time I used a MAHLE gasket torqued everything to specs and using the correct sequence started leaking right away I thought it was a bad gasket so I bought an OEM one dropped the subframe again and it still leaks, I’m sure it is not the rear main seal because it is coming from the front middle and back rear bolts i checked the torque converter and no oil splashed on it just to make sure it wasn’t the rear main, could it be a warped oil pan or excess crankcase pressure causing the pan to leak but I never had any issues with a leaking pan until I dropped the pan I made sure everything was clean before installed. could cleaning the pan in the sun cause it to warp, I did install the gasket dry as recommended or should I use a sealer as well I really don’t want to drop it a 4th time

Curious as well, Thought it was my rear main seal or flex plate bolts being installed without sealer. Installed new rear main seal (complete with rear cover) and new flex plate bolts with sealer, still have oil coming from bell housing area.

just noticed a leak on my car also, got the oil changed and the people let me go below and look, looks like the hole oil pan was leaking, never took the pan off or anything.

any ideas?

Obviously you didn’t install something correctly, or there’s a defective part...that’s the only explanation. Your procedure was absolutely correct (if in fact your sequence and torque was balls on accurate and the mounting surface was practically sterile.

That leaves some sort of issue between the beginning and end of your install.

“When you have eliminated the impossible, whatever remains, however improbable, must be the truth?”

Two choices. All new parts including pan.

Or take it to the dealer and make it their problem to make right with warranty.

Did you ever have the leak fixed? What did you find if you don't mind sharing.
