Why do I get a puff of blue smoke when I start my car?
Typical valve guide leak results in puff of blue smoke upon start up and once it gets worse it will also show up after engine idle at a traffic light as well as start up. How often do you change oil? Your vehcle is too new for a valve guide issue unless you dont change oil properly.
Why do I get white smoke when I start my car?
If under warranty then take to dealer otherwise pull spark plugs and check them to see if burning clean and all look the same. Should be no build up and insulator should be clean. White smoke would be steam which is indicative of a cooling system leak into the cylinder.
What does puff of white smoke on startup mean?
White smoke would be steam which is indicative of a cooling system leak into the cylinder. You may want to check the oil and make sure it is not milky looking. Cooling leak is either cracked head or head gasket. Re: Puff of white smoke on startup? Nope, not blue. Very white. Like a cloud is coming out the back of my Mo.
When does the puff of white smoke go away?
After she drives home (about an hour drive) it will sit for a few hours, and then we go to run errands. On startup, there is a puff of white smoke for no longer than about 3-5 seconds, then it goes away and all is well. It doesn’t do it while driving.
