Ok, Well, I still haven't nailed down the exact point of oi leakage, however, I have discovered something that is a little more critical...at least I think. I'm hoping that you experts can shed a little more light. I pulled the turbo off the truck and removed the compressor housing and there was quite a bit of oil residue in there. Now my compressor wheel had a little bit of dark oil like residue on the blades and I'm assuming that this is mostly from the Crankcase Ventilation System...cue the expert chime in at this point gents. Continuing on, I removed the compressor wheel and low and behold there is quite a bit of oil residue on the back side of the wheel and the compressor housing. No expert on turbos here, but I would say that the leakage limitation for the compressor shaft is zero. Well, being the inquisitive person I am, I pressurized the oil inlet port/blocked the return with 10 psi and noted leak down through the compressor shaft seal. Continuing with the exam/teardown, I noted about .002" to .003" of shaft play 90 degrees to the shaft within the journal and no play along the length of the shaft (side to side). Once again, not an expert here ...cue the expert chime ins...I'm looking at a much needed rebuild/upgrade? Am I correct on this one guys?
