UPDATE : got home and I tried the clear plastic tube suggestion... What I noticed was rather puzzling....Once I started the car, the clear hose went flat... Looks like the carb vacuum can't suck anything. When I popped the PCV valve off the cover, the little rattle inside the valve was stuck upwards. I guess from the suction. However If I put my finger tip on the PCV valve it quickly sucks my finger. So I know its sucking in the air. I guess the hose is just flimsy....I didn't see any oil going up the hose.

So now i tried the second suggestion of spraying carb spray into the valve cover hole for appx 15 seconds. The idle did not jump up either.

The valve covers do not have baffles. I can see straight down into the head....


All of this was tried under idle. I didn't drive the car around....

There is quite a bit of suction on the valve so having the plastic hose go flat is common. Maybe a stronger re-enforced hose would help, like the stuff that has the nylon webbing in it.

Traditionally, the booster goes on the rear of the carb base plate and the PCV goes on the front and then to the drivers side cover. It's not set in stone but that's how it's usually done.

If you don't have baffles, you need them! At idle, there won't be much, if any, oil getting sprayed into the PCV valve area. But wind it up a little and watch out! LOL Oil is going everywhere and the PCV valve is like a giant vacuum cleaner hose just waiting for anything to come along.

You really don't need to pull the header since you know that the PCV system is the conduit for the oil usage. You need to either add baffles or change to better covers. (can't beat stock!)

The black stuff you are seeing is most likely due to a bad header gasket. I think in an earlier post you said you had a loose header bolt. That will quickly lead to a blown gasket.

Do you still have the original valve covers, if so pop them on and see if the issue goes away. Your issue sure sounds like the PCV is sucking oil due to lack of proper baffles.

At this point checking the plugs isnt going to tell you much, you already know oil is getting into the cylinders so at least some of the plugs will be black.

Just took the valve cover off to make sure there are no baffles. And sure enough, there arent any....

Also pulled the header back to where I could see the other 3 exhaust ports and what i saw was scary....

PICS ARE UPLOADING....

Inside of the valve cover:


The other 3 exhaust ports. They look good and dry. Looks like they're burning right:

Some valves will be open, it just depends on the camshaft position when you turned it off.
