Default crank case venting problem w/ oiil vapor canister?

Ok

I have a 65 sideoiler, MR heads, solid lifter cam, Iron MR heads that have all been rebuilt (heads have bronze guides etc). I am running the pentroof valve covers (no vents) and I have the oil vapor canister on the firewall with 20w50 Brad Penn oil, and avaid 9qt pan.

Now here is the problem, I think I have too much condensation building up. I also pulled the #1 plug yesterday and had some oil iin the threads which leads me to believe there is too much pressure buildup in the crankcase forcing oil and oil vapors past the rings and valve guides into the combustion chamber. I also get the occasional smoke burn out of the pipes as if il is pooling in the heads.

When using the oil vapor canister system, are you supposed to remove the wire mesh backet/collector in the intake to allow better flow into the oil vapor canister thus relieaving some pressure in the system?

Any thoughts?
