[QUOTE="Bluthndr, post: 102263, member: 2182"] Just my 2 cents I would check it out with an IDS. I have one that started rough and smoked white - now that you mention it i think it was usually the first 2 of 3 times started in the morning. Maybe part of engine management strategy? All looked good (data/pids), but power balance showed one drop out most of the time first few minutes of run time. Relative compression test on IDS showed one cyl 12% down and teardown revealed intake valve impressions on the 4 rear holes, #5-8. Cause of miss/white smoke (for this one) = low compression from a cyl #5 intake valve leaking. Visually the head looks perfect, but solvent leaks out when poured down intake port. Glad we found it before the valve came loose and wrecked pistons or the block completely. Just wish I knew why there was valve to piston contact in the first place. If the IDS hadn't caught it would have certainly gone down the road a while longer. Something to think about Just my 2 cents. By the way. Love your truck Eric. [/QUOTE]
