Moderately accelerating in 2nd or 3rd and I can hear air, ssshhhhhh, increasing louder and louder as boost climbs. The sound starts at about 7-8 psi and is preventing me from boosting above 15 psi or so. Checked the entire circuit except right at the turbo outlet, the bov, and the intake manifold. What's the most likely culprit? And are there procedures for testing the bov? Can I charge the manifold with the valves at TDC to hear leaks at the head seal? Have hard IC pipes, and a stock bov and manifold. Thanks.
