That's usually a sign that the engine is burning oil. Could be worn piston rings, bad gasket(s)... check that there is not too much oil in the engine. Make sure the PCV valve is functioning (if it has one). If it's been happening for a little while you can check your spark plugs for signs of oil (unscrew one and inspect the ignitor).
HI do you now the color of the smoke if engine emits white smoke its not burning the fuel it could be water mixing with fuel = head gasket even tho you dot have water in the oil if engine emits black smoke - that's excessive fuel to air ration check air filter & air inlet to see if clogged if engine emits blue smoke - excessive oil consumption cloud be valve seals
oil leaks could be coming from a few spots ,valve cover gasket ,oil pan gasket and a bad harmonica balancer seal ,and the white smoke coming out your tail pipe is a sign of a blown head gasket ,check your dip stick and if the oil is creamy is your head gasket
blue smoke is usually oil burning- is it light or heavy- if light- change oil and go up one grade- rings are worn- if heavy- time for a rebuild- rings need to be replaced. but for the money on rebuild- could find car newer and lower milage
The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.
Hope this helps and thank you for using FixYa! Have a good one!
when a car is smoking from oil leaks like what your describing its due too several things. commonly is that your head gasket could be torn or just old and is mildly leaking oil into your piston cylinders. The other issue is your piston rings could also be bad and in that case you will have too pull the bottom half of your engine apart too replace the rings. Oh i almost forgot that the valve cover gaskets could also be old and that would cause a leak onto your exhaustmanifold, thous causing it too smoke as well
Does the car emit blue smoke from the exhaust when driving? If so, either the piston rings or valve seals could be bad (expensive repair). The PCV valve could also be bad. The last reason (but no blue smoke) might be a physical oil leak due to a loose oil filter, drain plug, leaking oil pressure sensor, or worn crankshaft seal. Good luck!
So upon startup the car has a little smoking going out the tailpipe? Then it goes away after the car warms up a little? You probably have stuck piston rings and are burning oil at first until the car warms up and the rings seal better. What kind of oil are you using? What weight is it? I don't know what is in the car, but if it is conventional oil at 10w-30, try changing it to synthetic and using 5w-30. I don't know what that car comes with from factory or calls for, but in my experience I've stopped oil burning in a piston engine with thinner, synthetic oil. This helps to unstick the rings allowing them to seal better AND the thinner oil doesn't collect on the rings so much, keeping it from burning or going out the tailpipe. Also, synthetic doesn't burn and carbonize like convention oil (dinosaur juice) does.
I really hope I understood your problem and helped you with it. If not, please clarify. Good luck!
The best test is a compression test.
Blue smoke means it's burning oil, due to worn out piston rings.
White smoke means it's mixing antifreeze and oil due to a bad head gasket or cracked head or block.
