pcv sucking oil ?

It's not the pump, that's a 2 second deal. At most. What is compression? Doesn't need to be above 140. Cam same, mine 150, and worn out.but all within 10%. Check and read plugs.

If rich jets- have you blown all the soot out the exhaust? I;ve had rich on holleys and eddys. Holley- main primary jet or power valve. .110 in sec vac is no problem. Figure this out first, then read up on Holley cam placement. Doesn't sound like the problem.

Eddy- easier, but you run out of tuning parts before you get it tuned. And those jets, rods, and springs ain't cheap. And still can't tune a mild 440.
