Oil leak saga 2001 Denali

[dsrour]

My 01 Denali w/ 80k miles, developed an oil leak. Seems to drip off starter motor bolt and on left side about level of oil cooler line into block.

Took to dealer and they replaced valve cover gaskets, pcv, which I didnt think were the problem and of course it still leaked. Took back and they replaced the oil pan. Guess what, it still leaks. They claim to be very preplexed and say they have never seen a leak from a Denali. They are now talking about rear main seal.

I don't have a lot of confidence in them as you might surmise. Any suggestions would be hugely appreciated!

Thanks

My first guess would have been the Rear Main as well.

Mine started a really slow leak at 62k.

How hard is it to replace rear seal? tx

Pull the tranny and torque converter back. The seal on the back of the motor b/w the oil pan and engine block.

thanks. you don't have to pull tranny completely out?
