Couple pics of what i got going here, have a hard explaining things on the puter..............maybe some of you have noticed this..........lol

Anyways pcv hose hooked up to the F-pipe behind the center carb, no other place to put it.

These are the cheapy breathers i have...................let me know if i can get better ones.

The rubber plug is the one in the v/c thought that would keep the oil inside the valve covers better, will pull out and see if that makes any difference.

Just thinking out loud here, the last two rebuilds i believe were with the gapless rings, is this my problem or just poor work done by the builder.

Im hoping some motor pops up for sale similar to what i have now, but so far seems all the motors for sale are race type.

Whats really weird about this whole deal, the dipstick is only a little down from full....................i use 6 qts

I want to make sure I understand those rubber plugs. If they are made like a sleeve with a closed bottom, that's a problem. The bottom of the rubber plug/sleeve needs to be completely open to the breather. I have seen some of those with just a razor slit in the bottom. No good. It needs to be completely open to the breather, at least on one side of the engine. As far as how much of a leak is "normal"? Of course dry is best!! But not easy to achieve. To me after taking the car out and ripping it through the gears say 4-5 times and driving it around 20-30 miles. if I park it on a piece of clean cardboard, I would not expect to see more than a quarter size stain on the cardboard. If I had a stain the size of a 1/2 dollar, I would be a little unhappy. Not very scientific, but that's my personal threshold. One of the reasons I bought a smoke machine.

Mike, a few pics of what i have with that rubber plug

quarter size stain on the carboard..............damn i have a dollars worth of those after some high 5 thou runs..............not to mention, days after its still the same.

Really nothing bigger than a half dollar stain wise, but i have quite a few of those.

Are you talking about one drop after a drive..............if so im in big trouble, i get drips 2-3 days after a hard run.

Glad your hanging in there with me on this...............

Pics of the rubber grommet im talking about.

Worse case Sincero.............if i drive the car under 3500 rpm, the leaks are not all that bad..............if over 5000..............they are really bad.

I will buy a smoke machine................would be great if you could give me a # on what model you bought............

Problem with the smoke machine, say its the rear main or oil pan seal.............doesnt really matter if i have too much crankcase pressure does it.

Cut the bottom of those plugs wide open or ditch em for open versions.

PS, prolly a big part of your rear main problem.

If I am seeing the pics correctly, it looks like those are rubber plugs. Even if they have tiny holes in the bottom they can't let that big crankcase breath properly. I would cut the bottom off one of them, clean the engine bottom up and go for a drive. Problem may be solved. The PCV system can't work if outside air can't get into the crankcase and push the lighter crankcase gasses into the PCV hose and valve. Working properly, it's a loop. Outside air through the breather into the crankcase, pushing blowby gasses up into valley cover, through PCV valve, through hose, back to the intake to be burned.
