Question engine oil loss

New to Jeeps and new to the forum--have an '88 Wrangler with 258 4.2 6.

Offenhauser intake manifold
tuned header sys
Holly carb

removed 90% of all smog stuff incl cat converter

After changes engine runs very strong and has a lot more top end but having trouble with the oil comming out of the rear elbow fitting (CVC) on the top of the valve cover.

Is there a way to seal off the fitting and not harm the engine?

see this link
One of the first concerns is the health of the
engine. Do we have a tired old engine allowing
the blow-by gases to pressurize the crankcase?
If so, the pressure would force the oil up the
PCV breather hose and contaminate the PCV
breather filter and air filter."

do not block off the crank case vent!
"The danger to America is not Barack Obama but a citizenry capable of entrusting a man like him with the Presidency. It will be far easier to limit and undo the follies of an Obama presidency than to restore the necessary common sense and good judgment to a depraved electorate willing to have such a man for their president."

on the pcv valve toss and oil separator kit on the kit put a small air filter then you will not have oil going all over your engine bay. Problem solved
