I'm having a serious cloud of white smoke out of the pipes when I start in the morning. It seems like this should be the valves going bad. I want to know how much would a good complete valve job be? What are some things I ask the machine shop? What should I look for on the bill? Do I need to replace the valves and springs, or just the seats? If I do, should I buy the parts, and have them install them, or just let them do all of the work? I think I have comp cams parts, but I have never taken off the valve covers. TIA graemlins/beers.gif
