I just bought a 97 dodge avenger for 1000, but it has some problems. When i first turn the car on white smoke starts to come out from little to alot. then when im driving around the city it smokes but not too much, in the highway it doesn't do it at all. What could be the problem? also, the seller, told me that i had to add oil like every 3 weeks. i dont know if there is an oil leak . i dont know whats going on?? is the oil and the whit smoke has to do with something i just find it weird to add new oil every 3 weeks. what could be wrong with my car?? also how much do you think all the repair is going to cost me...
Oh, i have a friend at my school that's taking Auto Tech3 and he said he thinks that it could be the head gasket .. oil going to the combustion chamber and producing the white smoke. he knows alot about cars, should i trust him and let him try to fix it? please give me an answer thanks.

White smoke 99% of the times means coolant or water in the combustion chamber.
The majority of time it's a bad head gasket, so your friend is most likely correct.
Get a compression test done on the engine to verify. A compression test will determine if the head gasket is bad, and also let you know which cylinder(s) has the bad head gasket is bad.
If you can get your friend to throw in the labor for free (which is the most expensive part of a head gasket replacement). The head gasket set should around $150.00.

White smoke usually indicates that coolant is getting into the combustion chamber. This could be because of a bad head gasket, or it could be more serious, such as a warped or cracked head. I suspect that the reason the seller told you to add oil every 3 weeks is that the oil is getting contaminated with coolant, and the car is probably burning oil as well. If I had to guess, I would say the engine was probably seriously overheated in the past, resulting in a warped head and cracked rings. Look for a used engine with a warranty at a wrecking yard , it will be much cheaper than trying to repair the one you have.

Rover cars were notorious for belching out white smoke. It usually only happens in the winter or when you get a cold day.The exhaust system takes quite a long time to heat up and burn off the moisture inside it.My current car which is an mgzr 160 has the same problem.It does not leak water or burn oil but it does love producing white smoke.MOT emission test was ok so there are no faults in that department..What you should do is take your car for a good long drive up the motorway as fast as you can get away with for 20 miles then come back again and see if the bugger is still puffing out white smoke.

If it's only white smoke then you'd get away with a head gasket, worth a go.. if there's no blue smoke you might be ok
I'm guessing there is cause it's using oil.
That would mean a rebuild, can be done on the cheap, or just try driving it and see how long you can get. It might go on a year like this, try changing the oil and put in some thin oil if the smoke gets too bad (ot maybe thicker oil?? I never tried this!)

Your friend is right in that the problem is oil getting into the combustion chamber. This could be because you need a new head gasket or possible a ring and valve job.

White smoke is usually an indication of a head gasket leaking coolant. It's possible to also leak oil. Please check the oil and see if it is "milky" or looks like cappuccino. Ether way, you are doing some major work.

White smoke>>>Oil burning (ussually a leaking gasket)
Black smoke>>> Fuel burn not correctly adjusted
White smoke in Rome>>> New pope is elected!!
Not difficult to change and easy to get parts. Good luck.

Large amounts of white smoke is usually anti-freeze burning from a blown head gasket.
A little is usually steam from exhaust condensation
Blue smoke is oil--- bad rings or valves.
Black is fuel system problems.

If your car is burning oil that much then pull out the spark plugs and see which cylinder is affected. You've nailed it when you see one that's oil covered or oil sooty. If you are burning coolant then you would be low on antifreeze and perhaps have an overheating condition

oil is leaking into the cylinder and burning with the fuel and air causing the white smoke
