My name is ***** ***** I will assist you.

Are you leaking in the turbo inlet or exhaust as well? Remove the piping and see what else you have for oil. There is a good chance you have a bad new turbo.

what else should I be checking
Expert:  Jeremy replied 1 year ago.

I would be checking to see if you are getting oil out of the exhaust manifold. To be getting that much oil in that short of time is a huge concern!

That is why I was asking on which side you se oil on the inside of the turbo to get an idea of where the oil could be coming from and spitting out the wastegate. If it is both sides of the turbo, then the turbo rebuild that was done was not good and it is leaking at the internal seal. If on boost side, then the turbo has a blown impeller seal. If on the exhaust side, then it is coming from the engine and you could be having a need for a oil ring on one of the pistons.

Definitely look in those areas to narrow it down. If this didn;t occur until you got the turbo, then the new turbo was put together wrong.

I see you viewed this and this is still showing as a open question due to no positive (3 stars or more) rating.

Did you still need assistance with this?
