Me and a buddy were trying to see where my Ty has a small oil leak,and he thinks it is from the turbo oil return line.Is this common,is there an easy fix,or is it a hard fix?Any input would be great ;)

Re: oil leak

Pull the right wheel well and get a good look at the turbo. Prolly a drain fitting gasket and/or the turbo drain fitting at the pan, which is a bit of a bugger to get to. There’s a short piece of hose there also. One more thing, the turbo drain and another line are really close to each other at one point where they cross (at least on my truck) so check that as well.

The gasket is avail. aftermarket, do a search for part #.

Re: oil leak

Try these numbers. I believe the GM # is discontinued. Also an old post indicates that it's the same that Cat uses on their 3500 series diesel engines??
Also check with Tucker Auto Parts - 1-877-858-2447 they know SyTy's

I just made mine.

Re: oil leak

I tried several dealers looking for the gasket, and struck out; "discontinued", "don't have one", etc. I even tried the Mitsu dealer. I finally ended up getting one from a Kenworth dealer that also sells used stuff like the Mitsubishi Fuso; afterall, it is a Mitsu turbo. Making one is tit though.

EDIT

the other line that you're talking about that crosses the return is the turbo coolant line. They do come pretty close, but shouldn't touch / rub.
