Engine/Transmission (1998.5 - 2002) White smoke

[BIGDIG]

Ok,so how bad is it when you look in your mirror and see a little puff of white smoke when starting to accelerate from a stop

White smoke usually occurs when there is not enough temperature to burn the fuel. The unburned fuel particles are then exhausted usually by a rich fuel smell.



If the problem persists after the engine is up to operating temperature several other things should be checked. A faulty injector can cause white smoke. Timing is often a factor when white smoke is excessive. Low engine compression can cause the problem and the injection pump can also have problems that result in white smoke. Air in the fuel system can also result in white smoke.

TMTT-I only noticed it once,I'll keep looking and reply on it later. hope its nothing. only 28,000 on it. .

Another thing is how long do you let it idle before taking off? If left too long the combustion cambers cool off drematicly and diesel can begin to wash down cylinder walls and can even collect a tiny amount of unburned fuel in the piston dish and that can cause white smoke too. Alltho in the summer it's not too likely.
