Just did a boost leak test because car has been running sluggish for a while. Noticed that air is coming out of the valve cover breather port that goes to intake. It never use to come out like this, now I hear it hissing out and lose all pressure within 15 seconds. I Ruled out the pvc valve because I use that line feeding the pvc valve for my pressure gauge.
Not burning any oil and all charge pipes are clean. I have very little shaft play.
Any thoughts?

 

Anybody?
