Pop and white smoke from engine

The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air. Leaking coolant is a leading cause for white smoke coming from the engine. The cooling system flows from the radiator to the engine block. Begin by checking coolant levels in the radiator. If the smoke is coming from under your hoo that probably means you ignored white smoke coming out of the tailpipe, and now your engine is overheating.

Or maybe you completely forgot to add coolant at all, and the engine overheated. Not that anyone would ever do that. A popping sound coming from your engine can be bad news. If you suddenly hear a loud pop or bang in the engine area, pull over to the side of the road and check it out.

Be on the lookout for smoke or fire, two things you should never see under the hood. This is usually caused by overheating the engine and usually causes the oil to be saturated with water. This is particularly bad because the oil is not effective at protecting the bearings and can ruin an engine quickly.

In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. Now this isn’t always the case, but after some trouble shooting we’re usually the go-to shop when diesel drivers need refurbishe rebuilt, or new injectors. One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder hea a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine.

And then a very loud pop noise came from my engine and a lot of white smoke poured out of the hood and exhaust, I drove it around today as I was on my way to the auto shop and it seemed fine, no problems then. A thick white smoke that lingers indicates that the vehicle is burning coolant - which in most cases, means that you have one of a blown head gasket , a damaged cylinder hea or a cracked engine block. White smoke from the exhaust on a cold morning start is normal. The white smoke is the result of normal condensation which builds up inside the exhaust system. You may commonly see white smoke coming from the exhaust on cooler days upon starting.

This is likely due to steam created due to the engine burning off the condensation. Consistent smoke coming from the exhaust most likely indicates a deeper internal problem with the engine. A small puff of smoke during quick acceleration is acceptable with older diesel engines due to a lag before the turbocharger’s air flow can match the increased volume of diesel fuel injected into the cylinders.

Newer electronic diesel engines with common rail injectorssimultaneously match the speed of the turbo with the metered flow of diesel fuel into the cylinder. Could just be coincidence. A leaking or blown head gasket can allow coolant to enter the combustion chamber. This in white smoke coming from the tailpipe, usually accompanied by a sweet smell.

Solution: Your engine will need to be partially disassemble have the gasket replace and then be reassembled. Other processes may be necessary if the engine has overheated. It then goes up into the cowl area, gets sucked up and blown into the car through the vents.

If your car has a diesel engine , then the white smoke might be indicating that there is a problem with the fuel pump injection. When the fuel pump injection timing is off, it is difficult to determine the root cause. Smoke from engine or exhaust Inspection Service You can learn a lot about the health and well being of your car from the color of its exhaust. If it’s operating in tip-top shape, tailpipe emissions should be nearly undetectable.

But eventually these things get worse and worse until you have no choice but have to fix it. The black smoke may show there is a return fuel line which is obstructed. Fuel injectors and sensors might also be damaged.

A final problem which can be diagnosed from black smoke is problem with the air filter.
