What does white smoke mean in an engine?
Thick white smoke, on the other hand, can indicate a problem. In particular, it could mean that your engine is burning coolant, which could mean a problem with a head gasket or a cracked engine block. These are big repairs, but it’s important to address needed repairs sooner rather than later.
Why do I have blue smoke coming out of my engine?
Look for broken or disconnected hoses and remove and check the PCV valve. Shake it back and forth to make sure it rattles lets you know it is working. Due to poor maintenance sludge can build up inside the engine’s cylinder head not allowing the lubricating oil of the valve train to drain successfully back into the crankcase (oil pan).
Why does my car have smoke coming from the exhaust?
If you’re driving a diesel vehicle, it’s possible that you have a faulty glow plug. All of these are issues that are best fixed quickly. If you don’t fix the issue it can become a compounding problem. A car burning oil risks fouling its spark plugs, overheating its catalytic converter, or even blowing its motor.
How does an engine get rid of smoke?
Engines are designs with a crankcase ventilation system of some kind to allow internal crankcase pressures to dissipate. This system can be built into the valve cover using an internal baffle system or the job can be done by the PCV valve (positive crank ventilation) and a breather.

What causes black smoke coming from diesel engine?
Sometimes if you’re carrying a heavy load with a diesel truck you’ll see a small puff of black smoke, but even that should be minimal in modern well-cared-for engines.

Why do I have gray smoke coming from my transmission?
Truly gray smoke is most frequently caused by burning transmission fluid. Checking your transmission fluid is easy, and by evaluating the fluid on the dipstick you can learn a lot.
Why is there smoke coming out of the exhaust after an oil change?
This can occur if coolant is leaking into the head. It could also be as simple as water entering the exhaust or carburetor after the engine was pressure-washed. On the other hand, if the smoke is a bluish white, oil could be bypassing the rings on the piston or valve seals and being burnt in the combustion chamber.
What’s the white smoke coming out of the tailpipe?
Under normal conditions, you probably won’t see the exhaust coming out of your tailpipe. As mentioned in the introduction, you might occasionally see a light white color, which is just water vapor. It’s important to understand that this is very different from the thick white smoke that brought you to us.
How can I tell if water is in my motor oil?
Bubbles on the stick, a brownish residue just above the oil level, or milky-brown oil with a thick consistency are all indications of water in the oil. Check for white, sweet smelling smoke coming from the tailpipe. This is an indication of coolant in the oil being burned off. Turn the engine off and let the vehicle sit for a few hours.

Why do I have white smoke coming out of my head gasket?
It doesn’t take much, but if tis white smoke has beenn going on for months without coolant loss, I suspect youare right it isn’t the head gasket. In that case it must be either water in the gas tank or some kind of air/fuel mixture problem. But water in the gas tank usually causes all sorts of performance problems, so that’s unlikely.
