Turbo internal oil leak
 

I installed my works stage 2 a couple weeks ago and I noticed oil leaking from my down pipe to front pipe connection. There is no oil leaking externally so I don't know where else it could come from. It's not leaking much because I've been checking my oil and haven't noticed the level going down. Just weird I'm getting oil in my exhaust.

Oil in the exhaust pipe indicates blown seals. Exhaust smoking a lot?

Or a blocked/pinched return line.

If you have an improperly sized feed line (many BB turbos require restrictors), or an undersized/blocked drain line, you can get oil blowing out of the seals onto both the intake and exhaust sides.

Either that or the seals are bad on the turbo, which shouldn't be the case if it's new.
