Having problems with your 2003 Chevrolet Cavalier ?
I have a 2003 Chevy Cavalier with almost 90,000 miles on it just recently I have noticed it is burning a lot of oil, however I have not noticed any oil leaking no residue on the ground or no smoke. I have been pretty good about have the oil changed on a regular basis. Why would I be burning oil - in the last month in a half it has required four quarts of oil .
Have you checked the pcv valve ( positive crankcase ventilation ). plugged pvc symtoms-- can contribute to sludging of engine. it will build up pressure in crankcase if plugged. the pressure can blow out seals, it can also force oil past oil rings and burn oil up in engine. shake pcv valve, if it rattles its ok. if all else fails check oil pan gasket and filter also. ive seen holes in oil filters or they are loose. and upon driving, pressure is put on oil and it blows out.
Four quarts in a month is a lot of oil! You would notice if it was burning it or leaking externally. Possibly the oil is transfering into the transmission. Check the trans oil level, if you have a dipstick to do so, if not have you noticed the trans shifting different or possibly running hot. If the trans is filling up at this rate it will start running out on the ground soon.
