Well I did see this though. Looks like I'm losing oil around the oil pan gasket. Below the gasket is covered in oil and above it looks dry. It's not enough to leak on the ground though.

I thought I was losing oil from the rear main seal or oil pan gasket as my engine looked similar. But it turned out to be the oil pressure sending unit. Reach behind the intake manifold on the drivers side. If there is oil behind the pressure sensor you have your answer. Much easier to change than an oil pan gasket!

Thanks I will look at that.

I thought changing the oil pan gasket would be that bad. But after looking at a few Escalade forums with 6.2's in looks like I need to drop the front diff to get the pan off.

Dropping the diff can be a PITA.

I tried it on my 02 Tahoe to make the long tube install/removal easier while I was building the exhaust: I gave up. was going to take me easily 2 hours

what oil are you using? I had oil consumption issues when using royal purple. the problem went away when I switched back to mobil 1.

Last time I used the generic Advance Auto synthetic. Won't do that again.


This time I used mobil 1 synthetic

just change oil every 3,000 and use 1 qt AFT to clean the carbon from the rings will help, most people will remove the diff to change the pan gasket but still only maybe extra 1/2 hour to remove. Or install new pistons and rings-your choice.

I haven't done anything yet I'm just keeping an eye on the oil level. I'm going to remove the pan and change the gasket. While I got the diff dropped I'm going to go ahead and put a drop diff on since I'm leveled 2.5" in the front and go up another .5" to 1".
