What causes the engine to smoke? |
[Edit] |
Answer
What is the temp gauge reading? Does it overheat? Sweet smelling smoke out of the exhaust pipe is actually steam from water leaking into the cylinders and boiling off. You most likely have a blown head gasket. This is even more likely if the car has severely overheated due to a recent cooling system failure, i.e. broken water hose, bad water pump, hole in the radiator or heater core, etc. Also check for water in the oil, which shows up as a thick yellow goo (the technical term) on the dipstick or oil cap. A mechanic can perform a leakdown test to determine if there is a leak. From the symptoms you described, this one seems like a no-brainer. You should have the head gasket replaced IMMEDIATELY. A broken head gasket can cause more problems. Water leaking into the cylinders can break starters and flywheels. Water in the oil can degrade the oil's lubrication properties to the point the motor can seize. Once the head gasket is replaced, check for any other cooling system problems that cause overheating or you may blow the new gasket.
It could also be worn piston rings if the motor has high mileage
Answer
I don't know about a " No Brainer", There are a variety of possibilities. Is the smoke coming out the tailpipe?, is it coming off the engine itself, coming from the engine compartment? Clearly, more information is needed to answer this question.
Answer
Could be oil leaking out onto the manifold. Look for oil leaking out of the engine. You may need to replace the gasket under the cylinder cover (takes about 15 mins).
Additionally, smoke from the tailpipe will be of 3 distinct colors. White smoke is a coolant leak, blue smoke is from oil burning, and black smoke is an overly rich fuel mixture.
