Car exhaust smoke
March 31, 2023 Smoke from your car’s exhaust indicates an engine problem.
We sat down with a master mechanic at our Transerv Fitment Centre to see what your exhaust smoke says about your engine health, and what you should do about it.
When You See Black Exhaust Smoke
They reasons for this range from leaking injectors, which introduce too much fuel into your combustion chamber or a problem with the engine management system causing it to supply too much fuel. If you notice your engine isn’t running as smoothly as usual or that you’re burning fuel more quickly, you may have a faulty sensor on your hands.
When You See Blue Exhaust Smoke
If you haven’t seen blue smoke coming from a car, it might sound a little strange. Blue or greyish smoke is a sign that your engine is burning oil.
This is usually due to leaking valve seals, excessive valve stem clearance, or worn piston rings/cylinder walls. Depending on how worn these components are, you may see it coming out your tailpipe.
In addition to reduced fuel economy, acceleration, and rougher idling, burning oil means you’re losing oil, which can cause a whole other list of problems, such as shortened spark life and even a plugged catalytic converter.
When You See White Exhaust Smoke
Don’t confuse white smoke with normal white vapour that dissipates quickly. Under colder conditions, it’s normal to see thicker white vapour come from your exhaust due to condensation produced by the fuel combustion process. However, consistent dense white smoke, though, typically means that coolant is leaking into the combustion chamber. Coolant getting into the combustion chamber is a serious problem that needs to be addressed immediately. If you don’t get this looked at you run the risk of overheating your engine or causing serious damage to other components such as engine bearings.
The important thing to remember is if you see thick white smoke that doesn’t go away, stop driving immediately and call your local Transerv Fitment Center.
