Well, a few days ago I noticed smoke when I was following my van. Yep, it has a blue to it. I only noticed it during take-off from a stop. I checked the plugs and there was only oil on 3. Valves? The real question, do I replace all valves, springs, and retainers or just cylinder 3? I won't be able to do the work over here so I'm going to have to take it somewhere. I'll probably buy all the parts and just pay the labor. Suggestions?
