Black Smoke


This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for :

Faulty injectors (injectors need attention at about 100.000 to 120 000 miles)
Faulty injector pump
Dirty air cleaner
Turbocharger or intercooler faulty
Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)


White Smoke

Normally means that the fuel injected into the cylinder is not burning correctly. The smoke will burn your eyes.

Engine/pump timing out
Fuel starvation to the pump causing the pumps timing not to operate correctly
Low engine compression
Water/petrol in the fuel


Blue Smoke

The engine is burning engine oil

Worn cylinders or piston rings
Faulty valves or valve stem seals
Engine over full with engine oil
Faulty injector pump/lift pump allowing engine oil to be mixed with the diesel

wot the quickets way to repair the white smoke, its not to bad mainly when you start the engine and sat still?

Also possibly an injector fault, a burnt top hat or heat shield can screw up an injector.

I agree with trucky, white smog is vapourised not burned fuel, it'd fail an emissions test from the next street.

k cheers, can it cause any more damage to the car or not?
