During some work on my H22, found oil in the tubing from the turbo to the intercooler. (Using a GT30 @ 10 lbs. with occasional jump to 18 lbs.) Enough oil to get a dark line or small accumulation on my finger when swiping the inside of the tube. About 2000 miles since install, car blows smoke @ upper end of rev range, oil not visible @ intake man. side of intercooler. Shop where I bought turbo said some oil blowby is common. Comments?

 

Is the seal on the turbo bad? Do all turbos leak enough oil that you can see it?

 

what feed line are you running?i would look into getting an oil restrictor just tomake sure there isnt too much oil pressure

 

Sounds like too much oil pressure to the turbo. BB turbos need a restrictor.

blown seals in both the turbine (blown smoke) and compressor (visible oil in piping), i recommend a -3 oil send line and -10 oil drain.

 

Thanks for the information.
