What are the reasons for your car blowing white smoke but not overheating?
Here are the 10 most common reasons why your car is blowing white smoke but not overheating:
-
Blown head gasket
A breach in the head gasket is the most predominant reason behind a car blowing white smoke. This component is specifically designed to fail before the engine block does. Symptoms of a blown head gasket include rough idling, pinging sounds, or low coolant levels.
-
Engine oil or coolant contamination
Foam in the engine oil or coolant is suggestive of coolant mixing with your engine oil, which can cause white smoke to come out of your car’s exhaust.
-
Leaking engine coolant
A leaking engine coolant can cause white smoke to come out of your car’s exhaust. This can be caused by a damaged radiator, a cracked engine block, or a damaged head gasket.
-
Burnt oil
Burnt oil can cause white smoke to come out of your car’s exhaust. This can be caused by a damaged piston ring or valve seal.
-
Incorrect or low-octane fuel
Using incorrect or low-octane fuel can cause white smoke to come out of your car’s exhaust.
-
Leaky intake manifold gasket
A leaky intake manifold gasket can cause white smoke to come out of your car’s exhaust.
-
Defective or split EVAP canister
A defective or split EVAP canister can cause white smoke to come out of your car’s exhaust.
-
Faulty fuel injectors and injector pump
Faulty fuel injectors and injector pump can cause white smoke to come out of your car’s exhaust.
-
ECU malfunction
An ECU malfunction can cause white smoke to come out of your car’s exhaust.
-
Condensation
Condensation can cause white smoke to come out of your car’s exhaust, especially in colder climates.
