Little puff of white smoke when starting

Recommended Posts

is it every start up, or  cold only?        typically a  valve  seal  needs  time to  leak down,  so  an immediate restart  should be clean....    But on the other hand,  a hot piston will mask a pissy injector too.

....... pretty hard to race around and  smell that elusive  puff...  Pretty windy around here lately! :)


Should have  a blue haze  if it's  oil,  but  the sun  shining from different angles  can  change  the color big time.  


Lots of  definitive answers in my post!    LOL
