Hoping some of you can help me with this thing. I'm about to pull what's left of my hair out.
In my shop I have a 2008 Sprinter that originally came in with massive oil leaks. Aside from a crack in the oil pan, the seals for the oil cooler in between the cyl heads were leaking. I replaced those, and while I had everything apart, I started the motor to check for additional leaks and noticed a pretty significant amount of oil coming out of the exhaust outlet of the turbo.
Sourced a rebuilt turbo from buyautoparts.com, installed it, performed regen and road tested. Everything seemed fine so I let the van go. The thing comes back a week later with a failed turbo. Ridiculous axial play in the turbo and a DPF filled with oil. Great. Got a replacement unit from the seller, installed it and now I'm running the engine sans exhaust again and I'm seeing oil again. Enough to put little black dots on a piece of paper if I hold it behind the turbo. With a flashlight you can see oil seeping down the backplane behind the turbine while it's spinning. Buyautoparts has no answer for me, other than sending me another replacement or upgrading to a brand new turbo for an additional $450. My customer is ready to have my head so I'd rather not try and shake another $450 out of him unless absolutely necessary. I'm not convinced a brand new unit will solve this problem.
I cant understand how I'm having trouble with 3 turbos. Something else has to be going on here. I'm using 5w-40 synthetic oil, and I checked the oil pressure at the turbocharger itself. I'm getting 45psi at idle on a cold engine. I checked it on another known-good vehicle and it's the same. I don't know what else to check. Has anyone seen something like this happen before? Is this just really ****ty luck?
Thanks.
