Phil;

I totally agree with you about false air, but need to correct you on your statement about the PCV valve...

The PCV valve is ALWAYS open allowing Positive Crankcase Ventilation, hence the name, but its flow is fairly limited so it doesn't add up to much of a "vacuum leak" ...the ONLY time it closes is if there is positive pressure in the intake manifold (backfire)...it would be waaaay bad to allow the flamefront (and much moreso the pressure) into the crankcase.

Cheers
