My motor is smoking!

this is a clasic problem when you do a value job with out replacing the rings on decelation the carb is closed and you get a vacuum in the hole intake system and the oil is pulled past the weak oil ring in the old days this was a very common problem with people that did not want to spend the extra money to do it right and at my shop we would not do just a value on high milige engines but that just my $.002 worth
