2002 cavalier burning oil fast and smoking.Smoke is gray colored.The car is not overheating.There are no bubbles on inside of oil cap.Car smokes more when it's warm.Burning about 2 quarts of oil within 20 to 30 minutes of driving.No leaks on the ground no major visible signs of leaking from top or bottom of motor.

we can not see smoke, (actual location) and matters huge
a tech sees 2 things, (tail pipe end)

1. steam
2. or smoke
3. normal steam,

smoke takes long time to dissipate and smells like burning oil. and is.
steam dissipates fast, and smells sweet just like antifreeze smells and IS.
ask someone, that has a nose,
for sure a shop.

is this your first car or first time driven in winter. is it winter in you country? IDK?
so if cold in the morning, is your neighbors car smoking?
yes, bingo normal. (this is normal steam part of combustion)

cracked head or head gasket

Yes this is correct, you can get important information from the colour of smoke from the exhaust:

Blue/Gray Smoke: Blue/gray exhaust smoke is an indication of oil burning in the combustion chamber. These are possible symptoms and causes:
Valve Seals: Leaking valve seals will cause blue/gray smoke at startup because oil leaks past the seals into the cylinder after the engine shuts down.
Valve Guides: Excessive clearance between the valve stem and the valve guide allows oil to leak past the gap into the cylinder.
Piston Rings: Worn or damaged piston rings will cause blow-by resulting in blue/gray smoke.
Worn Cylinder Walls: Worn cylinder walls cause blow-by resulting in blue/gray smoke.
PCV System: A stuck closed PCV valve will cause excessive crankcase pressure resulting in blue/gray smoke.
Black Smoke: Black exhaust smoke is an indication of a rich fuel condition. These are possible causes:
Fuel Injectors: A leaking or dripping fuel injector will cause a rich fuel condition.
Fuel Pressure Regulator: A stuck closed fuel pressure regulator will cause a rich fuel condition.
Fuel Return: A restricted fuel return line will cause a rich fuel condition.
White/Gray Smoke: White exhaust smoke is an indication that coolant is burning in the combustion chamber. These are possible causes:
Cylinder Head: A crack in the cylinder head (around the coolant jacket) will cause coolant to enter the combustion chamber.
Engine Block: A crack in the deck of an engine block near the coolant jacket will cause coolant to enter the combustion chamber.
Head Gasket: A damaged or blown head gasket will cause coolant to enter the combustion chamber resulting in white/gray smoke coming from the tailpipe.

Hi..That is a lot of oil you are losing, The engine is definitely toast.

Is it worth fixing? Depends on how much this car means to you, Mileage of vehicle, and just how much money you want to throw into a 20 year old car..The engine will need to be completely overhauled or change out with a used engine probably close to 800- $1000 either way..Probably have a lot more into this than you can live with I'm guessing
Is it worth fixing?

Your issue could be a few things. Simplest first would be the PVC valve. Other issue would be valve seals, valve guides or piton rings. The blue smoke is from your vehicle burning oil

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_677dced97ad9bddf

no year, ?

try a new spark plug e and then if wires to spark plug , replace that too. and cap and rotor if it has that....?????



then when spark is good, check compression with any $20 gauge.

no year, i give up.

1976 accord? surely ive no clue.



smoke has 3 colors, (my rules not ASE)

1 black fuel (flooding etc) can seem gray but is black .

2: white and lingers., oil burning , bad. news.

3: white and fades fast, is STEAM, like moms tea pot, look next time..

smell white smoke, smells sweet, its toxic antifreeze.

smells like oil dripped on an hot exhaust? that is the smell of oil burning



smoke where, under front of car, or at the end of the tail pipe. ?????????????



how you like my smoke rules, even mom can figure it out.

I'm sorry to say your engine may be cooked.
Since you are adding both oil and coolant, and the color of the smoke is gray or white, you have the signs of the engine burning coolant.
The common cause is a leaking head gasket.

Hello white smoke is usually engine antifreeze,Blue smoke oil burning,Black smoke car running to rich on gas,gas is not burning properly.

Exhaust smoke is not a good thing, it can slowly destroy the catalytic converter. The color of the smoke is important to know, gray smoke is usually oil burning and white smoke is coolant.

Smoke usually there's a problem.... Bluish gray smoke means you're burning oil (could be a number of things like piston rings, valve seals)... White smoke means could mean you're burning transmission fluid, or there's a crack in the gasket or engine block.... Black smoke could mean you need your air filter changed, bad fuel injectors, bad distributor cap, ignition coil... I would guess it's probably black smoke coming out of your exhaust from the sounds of your symptoms...
