Well the car was running very well, and no more boost creep with the bigger turbo. So I started turning the boost back up. At 30 psi it was screaming and after a few pulls I noticed that when the engine went back under vaccum it would burn oil and clear out under boost. Since I am running a catch can that vents not to the intake the only thing that would do this is the valve guide seal. If I remember correctly the valve spring does not hold down the valve guide seal like most engines I think I might of lifted a seal under the 30psi of boost. Just starting to tear it apart to verify. |
