yeeeeps. pop off that oil cap to see if you have a smoke-stack!

When I took off the oil cap last time while it was running there was a small amount of smoke coming out. So I guess it probably is the rings.

Small amounts are OK. I'm not sure how much vapor can be considered "normal" though.
7M's "puff" a bit and breathe heavy but at idle there shouldn't be positive pressure (you can feel this putting your hand over the fill hole).

I have good comp on a fresh build and had to put bigger PCV hoses on as the ones I used weren't flowing enough on the dyno.
