Question
What would cause engine to inconsistantly have smoke from exhaust on start up and cause excess oil consumption.Does not do it all the time.
Hi Richard...well on start up i would suspect that you have some bad valve seals and oil consumption would suggest bad rings...if not too bad yet. try a bottle of lucas oil treatment...it will slow it down...does engine have a lot of blowby...remove oil cap and run engine put hand over oil spout...do you feel pressure comming out..or see oil smoke.. check for a bad PCV .. if open it could allow engine to suck up oil from the rocker and burn it....hope this helps
