boost leak in valve seal?

[5150]

so i was doing a boost leak test the other day and everything was good except i noticed thers was air coming out the oil cap and led me find out that inside my valve cover was being presuized, so does this mean i got a leak in my valve seal?

Have you checked your PCV valve? Plug off the manifold port on the other end of the PCV hose and do the test again.

Could be your valve seals...to answer your question, if those are the valves your talking about.
