    I have seen it mentioned that high oil pressure can blow the seals on this turbo.

    I've never had any oiling issues yet.... this may be the first. If this rain will slack off I'm gonna start tearing stuff apart

    Kinda hope it is the turbo, 4 bolts and its out. I've had a few turbos apart and they're pretty simple. I think I would try rebuilding one if that's what the prob is.

    I appreciate it! Not many Mississippi guys on the forum. There's a lot of local guys on torqueaddics but this site is far more informational!

    Good call Gus. It could be the oil drain location causing it. If I were closer Id ride over. Keep us posted and take pics!! I love pics!

    I just let it run for about 10 min and I can't get it to smoke..... what the hell! No oil in the intake piping either. Turbo was pretty clean. Now it has a miss at idle.
