Well mine is one of those in line. My problem is that after a leak down test, I'm getting air past the rings in 3 cylinders. The car runs great. Just when you hit it it's blowing white smoke out the pipes. They think the rings might be stuck on those cylinders. I run pretty light weight
oil/ conventional 10w-30wt as recommended by Roush. We'll see when they get here. They wanted to pull the motor and ship it to Roush, that's when I said wouldn't it be cheaper to get them here? FE bonanza there next week.
