Tangerine system with crankcase vented back to the intakes on both sides. After running this for a while, I checked in the air cleaners and no oil residue found.

Great system; well engineered and fabricated.

Cool, another tangerine tank ..... does your engine have or use cylinder head vents?

I routed a hose between the 2 head vents. I read about it somewhere here. Don't recall who suggested it.

Interesting, i have read that a few times on here. im thinking i will go that route on the heads and use a pcv for the crank case vent. i might even measure the pressure if any on the cylinder heads. Just to see what is going on in there.

I'm very interested to hear what you find. Empirical facts trump guesswork every time.

Yes, i primarily want to learn more on why some engines nearly fill their valve cover chambers with oil at higher rpm. was it because the crankcase had high pressure or because valve chamber had a huge vent along with high crankcase pressure?

However so far most info i have read about seems to support having lower crankcase pressure. Here is one example:
