So this is how I'm going to do my PCV/Valve cover breather set up.
Yes, I know the PCV is already a check valve, but once it sees more than 5 psi, air starts seeping past. This is bad!!!
So I searched forever, and decided the best way is like this. (This is assuming you have an emissions/PCV deleted manifold like me)
Out of boost: PCV -> Check Valve -> Intake Manifold
In boost: VC Breather -> Pre-Turbo intake
Tools you will need:
Check Valve (McMaster-Carr part ##7775k53)
3/8 X 3/8 Barb X MIP fittings for check valve (Home depot)
11/36 Drill bit
1/8" NPT to 3/8" hose fitting (Pep Boys, etc)
1/8" NPT Tap (NAPA)
Check Valve:
Tap & 1/8" X 3/8" fitting:
First, I decided I wanted my fitting right on the side of the intake manifold, near the brake booster line. This is for ease of access, and I thought it was a good spot. (Marked by black sharpie dot)
Drill your hole with the 11/36" bit, and then tap it with the 1/8" NPT tap:
And then finally, you just screw your fitting in:
