PCV leak

For you heavy thinkers out there -------------------------------------------

What if , i put a pan evac set up on the side i tested , and left the pcv on the other side ? what if i put a pan evac set up on both sides and left the pcv set up too ??


I do the latter. Jenkins covered this in his book. You do NOT run a breather doing this or you defeat the purpose.

At idle you have a normal functioning PCV valve and the pan evacs don’t do too much but they do help. At a cruise you have both the PCV and the pan evacs pulling on the crank case. At WOT the PCV does nothing but the pan evacs are at full pull.

I will data log this when I get my data logger to verify that it’s working as it should.

I called M.E. Wagner and talked to the dad before I bought mine. He was stumped at what I was trying to do, which is pull negative pressure in the crank case as best I can without a vacuum pump. As soon as I get some data on it I’ll send it to him, as he was very concerned his valve wouldn’t do what I want, but it does, and does it very well. I just need the PROOF!
