I have a 2002 Escalade and it appears the gasket for the engine oil cooler lines needs replacing. Has anyone done this job before? It doesn't strike me as something I can't do on my own. Also, if there are any tips, tricks or pics out there please post as I can't find too much online about this.
I just replaced the oil cooler lines on our '05 6.0 not so long ago. It was an easy job for me as I had the oil pan removed. I used the Dorman replacement lines from Auto Zone. They fit perfect, 2 things though, 1 make sure to tighten the big allen wrench screw on the side of part that screws to the oil pan (mine was loose), 2 the Dorman did not come with the 2 star locking washers to secure the lines to the radiator (NOT available at The Zone or other big box stores). You will read not to reuse those, I did, I was in a pinch. The old star locking washers are still holding to this day.
The common leak area on these lines is where the rubber get crimped into the steel lines. I have read that sometimes you can use 2 screw type radiator clamps to clamp down on those union points. I have not read that the gasket itself ever leaked.
If you do a search on replacing the lines here, you'll see a number of DIYs that ranged from an hour to almost 2 days. Personally I see it as a very easy DIY even with the oil pan still bolted to the motor.
Tips and tools needed to make this an easy DIY. You need an "L" shaped pick/small flat screw driver to remove the 2 star locking washers. A 10mm wrench or I used my 1/4" ratchet with a long extension, swivel and a 10mm socket, made very fast work of the bolts. TIP: plan on replacing lines or gasket when you are doing an oil change. TIP #2: pull the lines down past the oil pan rather than trying to pull them up through the engine compartment.
