I have a 1999 Cavalier and my oil smells like there is gasoline in it. Anyone know what the possible causes of this could be and if so, how expensive of a fix it might be?

First since your car is a 1999 it is fuel injected-no carburator. Second it is normal for some gas to get in the oil. When the engine is cold some gas and combustion will get past the rings until they warm up. If the oil level isnt over full then dont worry about it. But if the level is over the full mark and getting fuller or discolored, like chocolate milk, then their could be a few different possibilities and you should take it to a professional.

The procedure of changing the oil isn't any different. You didn't say what type of engine it is or what it is in (car, tractor) but make sure you have a big bucket or pan, diesels usually hold a lot of oil. Oil is rated for different engines; oils for gasoline engines will have a rating starting with an S like SF or SL. Diesels need an oil with a C rating like CG or CH-4. Some oils are rated for both but you need to make sure you get one with the C. No way to tell what weight of oil to use without knowing what kind of engine. If you don't have some kind of owner's manual, you might try to get the brand and number off the oil filter that is already on there, say something like "NAPA 1243" and go to your local parts store. They should be able to match the number even if they're not the same brand, and they might be able to recommend a weight of oil too.

Gasoline in the engine oil is most of the time caused by a blown head gasket. Check your oil dipstick and make sure there isnt any brown particles on it. If there is this means water is mixing with your oil too. There are many other possible reasons for this. The price to fix it really differs from what is wrong with your vehicle.

Well lets start here.. Your 99 Cavalier does not have a carburetor. It's fuel injected.. Nice to see that skipper was paying attention to the question.. A cause of this is bad oil ring on the piston. A piston has two rings on it mostly. Sometimes three but that has to do with high performance.. Or your valve guides are going bad. What i have mainly seen is the bad oil ring/combustion ring on the piston... Its lets the combustion gases past and into the oil.. Check for compression loss and have a cylinder leakdown test performed.

Does the car run OK and is your gas mileage acceptable?? I've seen this problem, as well as pumping fuel out the tailpipe. if the fuel pressure regulator is malfunctioning. You should have your car properly tuned-up as well, since it is older. Also, look at the back of oil filler cap to see if there is a lot of cruddy. Whatever you see there is an indicator of the condition of the entire engine crankcase, and it may do you some good to have the engine professionally de-sludged to get your piston rings to seal properly again. Don't use cheap oil, it only causes problems later..

carberator is leaking through your intake manifold when engine is off because your float levels wrong or your jets are loose, or you have a carberator vent hose tied into your valve covers or manifold that is allowing the overflow of the carb to flow through it . basically your carb needs a good looking after for correct vent connections and float settings the gasoline is passing through the motor to your oilpan there is no other way for it to get there......skipper
