SHOULD THE COLOUR OF MY EXHAUST SMOKE BE WHITE?
Speaking from a general perspective, a thin white exhaust smoke (similar to water vapor) may be nothing to worry about at all.
Depending on the outside temperature, condensation will develop within your car’s exhaust system and the heat heading through the pipes will develop a steam.
If it happens that your exhaust system is producing a thick, white smoke, it is likely you have a problem.
More often, this thick smoke develops because of a blown head gasket, damaged cylinder, or a cracked engine block, which is causing the coolant to burn.
Thick white exhaust smoke also means there is a leakage of a coolant, which could trigger overheating and put your engine at a serious risk of damage.
If your car is experiencing this, please call your auto repairer for a quick inspection.
EXHAUST SMOKE GRAY?
Just like a white smoke, gray exhaust can sometimes be difficult to diagnose directly.
There are litany of possible reasons your car is sending gray smoke out of the exhaust system.
Some of the possible reasons are:
A. A problem with the automatic transmission fluid.
B. A stuck PCV valve
C. A faulty transmission vacuum modulator
D. Excessive oil consumption
E. Bad Turbocharger
While these issues could be minor and inexpensive to fix, it is relevant to have a professional auto professional inspect this as soon as possible to prevent further damage.
WHAT IS THE MEANING OF BLUE EXHAUST SMOKE?
One reason your car may be producing blue smoke could be that your engine is burning oil.
If the valve guide’s seals or piston rings are worn out, the oil will leak into the combustion chamber which in turn will burn.
When you discover blue smoke coming from the exhaust system, you must check your oil and continue to monitor your car’s oil consumption regularly.
