theres only 2 ways the oil return line can leak. bad gasket between the turbo and return pipe or the rubber hose between the pipe and oil pan.

I bet your 2 bolts(8mm socket to tighten) holding the return pipe have loosened and the gasket is leaking

GM no longer makes the gasket. If you need to replace it you will have to make one.

gm never made the gasket mitsubishi does and you can get it from them. or any good turbo shop has them.

I had the same prob. Replaced the gasket (homemade) and the hose (hi-temp oil from the hose dealer). Alignment on mine was a bugger. Eventually loosened the fitting on the pan slightly and pointed it up just a little from its stock horizontal position. The line comes very close to the coolant drain line for the turbo so check for wear there. Not a fun fix due to space limitations (where on our trucks –is- there room to fix anything :-? ) but it can be fixed.

BTW the clamps on the short piece of hose at the pan may be single use clamps. You'll have to cut them and buy a pair of screw clamps.

Mike Lee at RPM makes and sells a nice stainless steel braided set up with all the nice fittings.

mike lees line doesn't work with internal gates. The 45 elbow gets in the way. You will need to replace it with a -10 straight. We found out the hard way Beautiful piece however when it's in.
