Hello Gentlemen, hoping someone can shed some light on this? I have a 1988 28' Wellcraft Coastal w/ twin 260HP Mercruiser 5.7L carbuerated inboards. I performed a complete tuneup/oil-change last week. After changing plugs, coils, distributor cap/rotor and ingnition module in both engines, I warmed them up before oil change. After the oil change, my starboard engine "smoked" excessively for 15 minutes??? I did spray-paint the motors as well. Ever since, it has done the same thing..."burning-smell" type of white smoke until it is warmed up...then none at all? I checked the oil level 15 times...it is fine...no water in oil...all cylinders firing...but have not checked the compression yet. Engine acheives full RPM's and except for this smoking problem at startup...runs great? Could it be a stuck valve?...worn rings? Both engines have 850 hours on them.<br /><br />Thanks for your help!<br /><br />Bob
