Took car to dyno and noticed that under higher boost levels like 16lbs that the cap is leaking. Catch can was empty WHAT COULD THIS BE A SIGN OF? Did'nt notice anything around any of the heads and car is running great. Thanks for any input. Car made 77x rwhp at 16.4lbs going to stop there until I figure out the cap problem.

cap could be defective?
could be getting some excess crank case pressure, pushing liquids, gaskets are holding but the cap isnt
first thing i would do is get a new cap.
how bad is the leak?

maybe your overflow tube is stopped up

Mighty Mouse I checked my overflow can and tube. Maybe I'll just try a new cap and see what that does.If it ends up being to much crank pressure what are some good suggestions to relieve some pressure. Thanks Smokinhawk I would say the leak is a little to much to take to the track and be on the safe side at high boost. I ran it last week on 7lbs and went 6.56 @ 106xx with only a 1.54 60ft. theres alot left. Thanks for the input
