thanks for the advise guys. I'll start with checking compression, if it's ok then I'll go from there. Maybe a puke tank.
The motor by the way is a 455 Olds. I did a recent oil change, 10qt oil pan. The oil was not milky it was pure oil.
Just wandering, I did a compression test about a month ago and my readings on the gauge were 170 average with a low of 168.5 to a high of 171.5. Is that good or bad?
