This afternoon I gave my car the Seafoam treatment and noticed some white smoke coming from around the turbo. I decided to investigate a little more, pulled off the heat shield, and noticed the white smoke coming from the wastegate valve.
Is this a sign that my is turbo is toast?
Is there a way to fix this?
Could this be the reason why I am hitting approx. 1 psi less than target boost?
Relevant info: 2002 WRX, Cobb Stage 2, TurboXS Stealth Back
Any help would be much appreciated.
