Thankyou Mr. Erikson...

So, swapping one of the breathers for a proper PCV system (whether it is a closed or open system) will make no difference to the crankcase pressure, but putting 2 breathers on each valve cover may give my engine the breathing capacity it needs and therefore lower the pressure?

Is it a common problem for 2 breathers not to be enough (keep in mind that I am not sure if crankcase pressure is the problem and adding 2 more breathers is not something that I am going to do unless I am sure)?

My engine is built from all quality parts and makes 500hp and 500ft/lbs. I do not rev it past 6000rpm. All components are brand new and were assembled with attention to detail. This motor has only done dyno time and about 20 miles.

Thanks again
