PCV to Checkvalve I am having blowby issues and I have searched a lot on this forum and people say to put a checkvalve in the pcv system. I understand fully how to install the checkvalve, but nowhere does it mention the checkvalve model or where to get it? Part#? Brand?
Anyone know?
Thanks

I used this one because it's compact and cracks at less than a third the vacuum (2.5"wc vs 8.4"wc), so I know it will evacuate at idle with low vacuum (like with a larger cam):

It's plastic, but then again so is the stock PCV. The only drawback (not for most) is that it's only rated for 15PSI. I, for one, am not going to be eclipsing 15 pounds for quite a while.

OBTW - It's worked perfectly for a whole season, and I've never had any crankcase pressure problems. Not even oil through the breather. That's with 10PSI on the stock engine.
