I was told by my friend who has a power stroke that it's unburnt fuel. Since they run off of fuel pressure.
If it is turbo diesel, then the turbo is blowen
How to make the timing Mark
in a diesel engine, no power and blowing white smoke, indicates a bad turbo on the engine
is this a diesel truck?does this engine have a turbo?if it is a diesel with a turbo,it will blow white smoke when cold till it warms upif it continues to blow smoke check your air filterother reason if it continues to blow smoke is the turbo is about to crater get it checkedalso check engine oil for coolant lossif coolant is leaking into cylanders,this will cause white smoke
It wont stop starting, it will pump oil out of the turbo and discharge blue smoke.
The black smoke is caused by too much diesel fuel being supplied to the engine when you first open the throttle. Quite often this happens when the fuel injectors are worn and /or the turbo is not coming up to speed quick enough.
loss of power after,or with black smoke , indicates the turbo has quit.
black smoke in a diesel can be caused by a couple of things:- dirty injectors, - a bad fuel pump - a bad turbo - incorrect fuel pump timing - or incorrect settings in computer - heavy acceleration from low RPM ADD A PROGRAMMER, mine has a sct x3 tuner, black smoke pores into the road when i roll unto it.
this will happen on all diesel engines (if its going to make reasonable power) its basically soot/carbon from the exhaust and unburnt diesel. on some high power turbo diesel cars there is proper plumes of black smoke. you only need be worried if there is blue smoke while on boost as this means the turbo is shot. but black = good
Black smoke can be caused when there is an improper air to fuel ratio . This can be anything from a plugged air cleaner,injector,turbo....
it can be unburned fuel damaged turbo charger etc. light amount of smoke can be normal large amounts = problem.
have a mechanic check your turbo.most will tell u that a turbo blows black smoke but can aslso blow white smoke when turbo is malfunctioning
