Hi Matt, I also need to say it's been doing this almost from new in 1977. So, not sure how that figures into the equation. But, valve guide seals might be close. Also, the left side dual exhaust seems to smoke more than the right side. And, if she blows, she blows (hydro-ing)! Guess i'd have to get a new crate engine then.
