This is a fresh build with under 2k miles on it. No reported knock maybe max was 25psi with Alky. I seem to have intermittent smoke out the catch can for breather. Haven't pulled plugs or anything yet. Car runs like a top. Oil is not milky and haven't lost coolant. It was smoking like this on jack stands. Also the car is not running a pcv if that makes a difference. Seems to be smoking on both valve covers..
