I then did a web search and learned that a valve from a s10 2.2 liter flowed significantly less at idle. So I installed an ACDelco 19313315. The idle dropped significantly and I think I'm going to stick with this PCV for my larger canned engines.
Thoughts???
Thanks!!


You might as well bite the bullet and call M.E. Wagner and buy one of their adjustable valves. None of the junk you buy today is worth bothering with.


Yep. Worth every penny.
