Engine smoking under hood

If the smoke is coming from under your hood , 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. Older engines produce more hot spots, which make the car smoking under hood but not overheating. Worn out piston rings and clogged PCV tube or valve are the culprits that cause this smoking issue.

The most common cause of white smoke from under the hood of a vehicle is an overheated engine. In this case, the driver is actually seeing steam from the radiator instead of smoke. However, if a burning smell accompanies the smoke , there is likely another type of fluid leak.

Leaking oil on the exhaust often does causes smoke to appear as the oil. If your engine puffs out an occasional stream of white smoke , it could be steam coming from your coolant overflow tank. Leaking and burning transmission fluid and power steering fluid will also create a cloud of smoke similar to an engine oil leak , but with a slightly more chemical aroma.

When I drive the car for more than minutes I get white smoke coming from under the hood and a burning smell getting into my air conditioning system. When I open the hood , I see the white smoke coming from the area which I highlighted with red in the first picture. The second picture is a zoom-in of the first one. I started the car and expected the white smoke.

The white smoke and overheating is usually a sign of a blown cylinder head gasket. When the car overheats for an extended period of time or is low on coolant (causing the temperature to rise), the severe heat can cause the cylinder head gasket to become compromised which causes oil to leak into the coolant and water to leak into the engine. If the smoke coming from under the hood of the car smells like asphalt or tar, then it is probably burning oil. If oil is escaping from the system and dripping on to parts of the engine , then it will burn off.

Also, sometimes oil will get into the fuel system or engine and burn from the engine running. This happens when a gasket gets bad. While there are several different causes, such as coolant entering the combustion chamber, a cracked engine block or cylinder hea or a leaking head gasket, if you notice any smells associated with the smoke, such as a sweet smell, the coolant may be the cause of the smoke. Be on the lookout for smoke or fire, two things you should never see under the hood. Occasionally, especially in older vehicles, an engine backfire can actually reverberate through the air intake and blow a hole in your plastic air box.

This is rare, but it’s something to look for if you hear a small explosion under the hood. If the smoke from under the hood has an oily smell, it is likely that the vehicle has an oil leak, according to Joseph Auto Service. I to have been having this problem.

I bought my car from carmax and about a week later after about min driving from my work I notice a burning rubber smell when I get out. I look under hood and I see white smoke coming from underneath the engine. I have no idea what this could be. I replaced my head gasket a couple of weeks ago but the white smoke still comes when I park. DIAGNOSE – BURNING ODOR COMING FROM UNDER THE HOOD SYMPTOM SUMMARY There is a burning odor emanating from under the hood.

The symptom may be more noticeable after the engine is hot or operated for an extended period of time. USUAL CAUSE This symptom can be created by numerous causes. He fixed it and I got it back. Change the oil if its due and keep an eye on the leak for now while checking fluid levels.
