Well i had thought that my PCV sucking up oil was the problem but now it appears its not. My new 383 is still smoking when you let off the gas and when you get on it. (Let my buddy drive it and followed him to see) Soooo frustrating. Guess its back to the shop that built it and see if they can tell me whats causing it. Such a downer when you spend $5000 to have a Brand new motor built and it smokes. Been a rough year.
