Oil Leak

[chilango1986]

So i have read a few postings about this, i had a oil cooling line break that poured all my oil out, so then i took to dealer to have replaced. Im still getting the same oil leak on the denali. Could it be a bad cooler line fitting or a gasket . Also does anyone have a write up on how to remove and replace the cooler lines. It leaks from passenger side.

my oil cooler lines are on the driver side and trans cooler on the passenger side. I replaced my oil cooler lines and housing gaskets but it turnned out to be my front diff output shaft seal.

My cooler lines are on the driver side as well, but when i took the truck to the dealership they told me it was the cooler line that poured all my oil. So they replaced it and said fixed, noticed same day it was leaking on the floor near the back of the engine closer to the passenger side so i just assumed it would be the cooler line again. Like a gasket or O-ring

valve cover gasket maybe if it looks as if it is passenger side I would think. Chevy 350's are notorious for the rear main seal leaking. Now for the oil cooler lines. There are two o-rings that are in the oil filter adapter housing where the lines go in and if they go it will drain your oil pretty quick. Paper gasket between the oil filter adapter and the block. Other than that there is really nothing else to leak on them.

I would not say they are notorious for leaking. All seals will leak eventually.

Man I replaced oil cooler lines because of a leak and I am still getting that leak but from the drivers side I have a 1997 Yukon GT
