I'll get a hold of Chris at Mitsubishi to order some new t.b. seals. Mine is a pretty good leak. We used a stethiscope to pin point it but the leak was plenty noticable by ear.... I was at dads shop. They have like a 180psi compressor and i just ran the compressor till it built up to about 35psi. It's a 120-150 gallon tank so it shouldn't have been running out. I held the fill hose on the nipple for 10 seconds and all the air just pissed out of the butterfly valve leak.

As for the turbo, I just called Brian at Precision Turbo this morning. He said yeah, it's under warranty and that they should be able to get it out the door in a decent time. That was my only worry. So i'll remove it tonight and ship it tommorow.

Question: What causes blown turbo oil seals in the first place? This turbo has less than 4000 miles, return line is 10AN braided, feedline 4AN braided, synthetic oil and ALWAYS turbo timed. Was never considered over-boosted either, 23# max. So i have done everything right to my knowledge.

Thank you.
