If you saw where the oil came out then that is the repair needed. It may not leak enough oil to get to the ground. Engine temp will make the oil leak smoke before it ever hits the ground. It may be valve cover gaskets because when they start to leak the oil gets all over the exhaust manifold and the exhaust manifold runs very hot. Rate if this helps

Probably a vavle cover gasket leak, small but enought to produce oil, in or on the surface of the motor doesnt take much to a lil smoke from aa hot engine...it could be collectiing in the canals ontop of the motor where the vlave covers sit on the head? or a head gasket problem....inspect it well after you run the car for a lil while, b4 it starts to smoke

Engine cylinder #2 misfire and smoke coming from rear of motor and will not start.


Well,you may have an oil leak,but #2 missfire may mean a few things.
Pull #2 spark plug and see what's up.

Check for a vacuum leak,also.

Your car shouldn't have just suddenly started burning oil. Its possible it's leaking in the engine compartment and the leak is dripping onto the hot exhaust manifold and the. The smoke is blowing out the back as you drive. I would think it's unlikely that the engine has been damaged since the check-engine light should have come on if the oil level was low enough to cause damage.

If hii find that bluish smoke is coming from the exhaust pipes, then the next thing to check is whether it smokes on acceleration or deceleration. If the latter, it may be just a valve issue. If it smokes a lot on startup, then it may be rings.

Hi Anna
The problem could be your oil pan. I have found that the plug (bolt for oil changes) can become useless when the rubber seal of it becomes brittle. Now if it was the oil that started smoking the smoke you saw would have been blueish grey. Make sure that it wasn't your engine coolant as well which could have very well been overheating in the process.
Have someone check your oil pan for leaks and damages (could be damaged from sharp rocks or hitting obstructions with the underside of the car). Another thing i have had seen is that when an oil change was completed that the mechanic initially loosened the bolts around the oil pan and cought that mistake after the fact yet didn't retighten the bolts. Chances are however you will need to have the underside of the vehicle checked as the damage for that kind of oil release is very likely related to it...

It sounds like you may need valve seals.
The oil sits in the head after the engine is cut off and leaks around the seals into the cylinder.
When you start the engine it burns the oil and sends the smoke out of the tailpipes.
It does not hurt anything much if it is not to bad.

Smoke is coming out from under my hood...checked antifreeze and oil so it fine


white smoke usualy tells about a leakage in the cooling. check that. dont forgett to refill. get it repaired or DIY. attention: could be really hot.

if it smells like fuel, a fuel line is broken. then dont drive any more since it can catch fire.

if the smoke is not white, go to the repair shop instantly.

My truck blows white smoke


Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck
