With 2 breathers and no PVC
Camaro Z28 1984 - trans. man. - Rochester - Camed. My car always had a tendency to give small jerks at low revs.
I changed the pcv twice, it didn't change anything, I plugged the PVC inlet line to the carburetor and I put a free pipe (without PVC) at the outlet of the valve cover.
Since then my engine runs much better and acceleration is better. I thought of putting a second breather (no PVC).
One on the left and one on the right of the engine.
Question: Does it have a risk for my engine?

Re: With 2 breathers and no PVC
there will be greater tendency for oil contamination (moisture,fuel) over time without the PVC- SBCs prior to about 1968 did not have pvc-just had that big oil fill pipe with breather cap at front of intake manifold
