Thanks for the write up.
I very much understand how a PCV system works as I possess a vocational degree in internal combustion engine technology and retired from Cummins Engine Co.
What I want is a Unicorn, a PCV that has very little flow (leakage) at idle, they all flow at idle manifold vacuum.
What started this was a high idle condition due to to much PCV flow at idle, like almost 200 rpm. Now I have that down to near 100 rpm which for the most part dropped my idle speed down to a more manageable level.
The PCV is still not right, that's the price we pay for a big cam.
