10-DAY OF CHALLENGES EVERY 70-80% CAR OWNER ENCOUNTER EVERYDAY.
DAY 6 : SMOKE FROM YOUR EXHAUST.
Smoke from exhaust can mean a lot of things. There are different types of smoke and each gives sign of a particular problem in your engine.
WHITE SMOKE : If the white smoke is thin it may not be a big deal as it maybe normal condensation build up in the exhaust system and it can quickly stop. But,if it's thick it can't be ignore as it's a bigger problem. CAUSES: blown head gasket,a cracked engine block etc.
BLACK SMOKE: Black smoke shows that your car is burning too much fuel. You won't want to spend extra cash of fuel,so it's not to be ignored. The first things to check are fuel injectors and fuel pressure regulator.
BLUE SMOKE: In this case your car is burning oil which means the valve guide seals or piston rings are worn out. Burning oil can cause rough start as the process can ruin car spark's plugs.
If you’re seeing this kind of smoke, check your oil regularly and watch for consumption issues. While an issue that normally should require immediate attention and expensive repairs, including some internal replacement parts, if your vehicle is old and the leak is minimal, it can be carefully managed by topping up the oil on a regular basis.
GRAY SMOKE: Gray smoke is hard to diagnose directly. Like blue smoke, it can mean that the car is burning oil or suffering from a bad turbocharger. Take the same precautions as with blue smoke, and check for excessive oil consumption.
Gray smoke can also be an issue with your automatic transmission fluid getting burned up in the engine. A faulty transmission vacuum modulator would be the culprit in this situation, leading to transmission fluid getting sucked into the engine and getting burned up.
Furthermore, gray smoke could mean a stuck PCV valve. The PCV system (Positive Crankcase Ventilation) cuts down on harmful emissions by recycling them back into the combustion chamber. However, when the PCV valve gets stuck, pressure can build and lead to oil leaks. Fortunately, PCV valves aren’t expensive, and can be a quick job for a mechanic.
