I understand how a pcv system is supposed to work and mine is now working fine. I'll know if my tube clogs up and I can clean it easily. I did that because I could hear it flowing thru the pcv valve at idle. Also having it plumbed directly into the intake affects the jetting and I have to turn the air screw to richen it up.
And finally, I didn't pull the idea out of thin air. My repair manual mentions two different pcv systems that were available on my car (Nova). One went to the intake and the other connected to the air filter and had a sealed oil cap. I imagine if I had the correct pcv valve either would work to release crank case pressure.
