But since you brought it up, by what mechanism are YOU then suggesting that any crankcase pressure gets up to the valve covers? Are you suggesting that there is only a passage/tube that goes from the crankcase up to the drivers' side head/valve cover to get to the stock PCV valve? If so, what good would such a crossover tube to the passenger side valve cover do then, since in your scenario, there would then be no excess crankcase pressure there to equalize anyway?
Nope ... I did not contradict meself (that would be counter productive to my current record of never being wrong). The PCV valve is there to prevent PCV, which is why many laymen actually mistakenly refer to the little plastic thinggy on your left hand valve cover as the Pressure Control Valve (PCV). The bottom line is that you should NOT have pressure inside of your valve covers - they just can't handle it. Valve covers have a direct line to your oil pan so any pressure is bled off by ... oil leaks - at the valve covers, or the oil pan, I've even seen it shoot out of the dipstick tube.

Where does that pressure come from you ask? Blow by from the valves (probably blow by from the rings too but that's food for a different discussion).

The only way that the right valve cover pressure can be relieved through the PCV is for the vapors to flow through the oil pan & back up the other side to the left valve cover to exit through the PCV. That's just asking for more vapor borne oil to get burned off through the combustion chamber & IIRC, that's what we're trying to avoid.

It sounds like we aren't going to ever reach the point of agreeing to agree so until I try out my cross over idea, lets just agree to disagree. It's gonna be SCHWWEEEETT to prove you wrong though.
