Ok, so i've been playing around with the new 20B set-up in the FD and was blowing oil out the oil filler neck nipple under boost. I've had problems slinging oil out of it on the track due to hard cornering forces, but not from pressurizing the crankcase. Anyone else have this issue? Second issue is that i plugged the rear facing nipple and loosened the oil cap until i finished building the oil catch can and someone noticed the loose cap and tightened it back up for me. I did a run down the street and it started smoking BADLY. I'm assuming that it's just oil blow-by on the oil control rings and that the residual will burn out of the exhaust after a lil more driving. It seems to have been smoking less now that i've let it run 15-20 minutes. Anyone have any insight or input on this? Is there any possibility of damaging the oil control rings?
