i just clocked my turbo the other day to get the turbine house a little more in line. I secured all the bolts and everything is tight, but now i am leaking oil inbetween the center oil housing and the turbine housing. Do i need to replace that seal?

 

which housing. hot cold?

 

its leaking from inbetween the turbine (cold) housing and the center part with the oil in it.

 

You can try clocking it back if you want to see if it goes away. Was this a new turbo? Its pretty common for older turbos to leak from there, this typically means you need a rebuild.

 

Id run it, and when you start seeing a nice accumulation of oil in your charge pipes and TB, call it a day and hit the junkyards.
