    09 V8 Puff of smoke

    Recently my car has been puffing out smoke intermittently, sometimes at start up and sometimes as i drive a way from idling a few mins, no large plumes, but can be seen from rear view mirror when i drive off or rev. Cannot distinct blue or white, any ideas? Car passed 70k miles (no over heating or odd noises)

    Sounds like something burning in the combustion chamber intermittently, so not a consistent problem normal with a mechanical failure. Get someone to drive it while you watch to get the colour.

    So possibly oil or coolant? Hoping its not a cracked block!

    Or just plain crap dropping into the cylinders, cracked block isn't intermittent, is the car losing oil or water?

    Car is in storage right now as i am out of country, will be back with it next week, ill top off oil and coolant to see if there is any loss, my biggest concern if these random smoke puffs can cause damage?

    Sounds like valve stem seals. Smoke on startup and after idling. If the longer it sits, the bigger the smoke, then likely valve stem seals. Also check for smoke after letting off gas in gear at speed. Does the car burn any oil?
