Well, I bought a smoking 350 off of craigslist, but it was only smoking on one side (oil in tail pipe). last night I pulled the head off of that one side, and 3 of the pistons looked normal, the other looked clean or washed. The head had a lot of carbon build up on that one cylinder. You could still see the hone marks in that one cylinder, and not the others. Does this mean someone has already tried to re-ring this cylinder? Would re-ringing fix the issue? Let me know what you guys think. Thanks, Scoggman Posted using the Full Custom H.A.M.B. App!
