Every time i turn the egnition on my car smokes blue smoke once it gets to normal temperature and your turn the car off and you turn it back on it wont do that again.. no idea.. anybody Please..
No gasoline internal combustion engine has yet been invented that would run perfectly at cold start.
Somehow it would have a rich air/fuel mixture while warming up to operating temperature.
And the catalytic converters which should burn off the extra hydrocarbons at cold start has not yet heated up to do its job properly.
Not unless you are losing coolant (which means there is a possible cylinder head gasket leak) or your tailpipe ends are squeaky clean, or your sparkplugs are very clean too and greenish, then you do not have anything to worry about. This is normal.
