Turbo turbine seals are not supposed to be designed for 100% oil tight. They are not made of rubber, but turkon.. made for extreme high speeds without galling up.

== Crank case pressure buildup is the number one cause of turbo bleeding oil.

== Second is it not spinning fast enough at idle and getting a vacuum on the intake.

Here is an associated video of why an otherwise healthy turbo, would leak oil...




== Also, if there is any crank case fumes building up inside your engine, this is a VERY bad thing for it. It tends to also starve the top-end of oil, causing the overhead cam(s) to wear out prematurely, etc.
