Most common reason for that is worn valve stem seals and or guides or gunk buildup in the cylinder head blocking oil return holes.... Or, broken piston ring or burned piston lands. (use compression test to verify that) Knocking can be from oil detonating in cylinder or bad rod bearing etc.

2005 BMWi uses oil. Smoke comes out of exhaust when car is started and if accelerated. Smoke does not smell like burnt oil - the oil is synthetic. What is the possible cause of this?


its burning oil! could be worn out piston rings/bore or valve stem seals/guides but check the engine breather system is not blocked first

2007 ford 4.0 v6 why are all my spark plugdls on passenger side oil soaked but drivers side is fine doesn't smoke did compression test all good not a blown intake gasket had it checked anyone know?


Hi Josh:
I'd put fresh plugs in it and drive it for a week, then check the plugs.
Sometimes you will get high compression readings that are not valid because the rings are soaked in oil so they think they are sealed when they are not.
With the engine off, you could try removing the oil filler cap when the engine is hot, then restart it. A little vapour is OK, a lot indicates bad valve guides, head gasket,or ring blowby.
Also, try checking inside the exhaust tailpipe. If it is oily sooty it is also an indication of possible ring problems.
Review the maintenance history. How many miles on the engine? Could be the engine is getting tired.

1992 es300 blue smoke from exhaust


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. So best bet is to have a local repair shop inspect for internal oil leakage.

Accleration, exhaust smoke.


Sounds like you have a fuel-to-air ratio problem causing you to exhaust raw fuel from your exhaust pipe. you could have bad fuel injector, fuel pump, or carborator, if you don't have fuel injection system. Running that way for extended times will fill your engine with carbon deposits that will need to be cleaned up. Also could lead to excelerated piston ring wear. Be sure spark plugs are working properly to insure fuel is igniting. Since spark plugs are ignited via the distributor and ignition coil(s), this system should be check if spark plugs are having irregular ignition. Check timing to insure distributor is working properly. If you have changed gas from premium to regular, this could reduce your engine power, assuming that timing was adjusted to the previous gas. Check owner's manual for proper fuel usage.

Running rough and white thick smoke from exhaust


sounds like you are burning coolant. sounds like you have a headgasket issue or cracked block. is your coolant level low?? in the overflow bottle and in the raadiator? something tells me that you will find that coolant is low. you are pulling coolant into the engine and it goes into the cylinder and pass the exhaust to the back of the car. the white smoke is the coolant burning off and thats why the car runs rough, because coolant is not flamable so it doesnt burn. this results in the spark plug not firing right and having rough running condition.

Chevy Prizm or Toyota Corolla 2000 valve cover gasket problem? Right after oil change, engine check light came on & car started smoking & losing oil. I took out all 4 spark plugs: they were in very...


The valve cover gasket isn't hard to change. Oil on the plugs indicates a more serious problem. Smoke from the exhaust would be from rings, rich mixture, worn valve guides. It may be that the engine is overfull (that would show on the stick). Oil loss from a leaking gasket would smoke under the hood and leave oil on the engine and the ground.

350 tbi backfires under acceleration. Smokes. Third spark plug from front of engine on passengers side wet with gas and oil.


Get a compression check of all cylinders. Sounds like an oil control problem (valve guide seals or worn piston rings. A complete tune up might help some and you might try a hotter heat range on the spark plugs.

White smoke coming from exhaust when accelerating


Is the white smoke steam or water? If so it is a blown head-gasket. Fix ASAP or you will ruin the engine. Or is exhaust blueish/gray or gray and smells like gas or oil. If this is the case then it could be a fuel injector, spark-plug (or no spark to plug), valve seals, piston ring/s, or clogged air filter.

Thick blue smoke. no oil leaks new spark plugs and spark plug wires. checked all cylenders cant figure out why its smoking.


Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?
