I purchased a 1992 Fiat Uno Fire 2-door w/hatchback in 2007. I change the oil a few times a year. I've had the engine block cleaned twice thus far. I think I have an oil leak possibly from a bad head gasket, but when I check the dipstick, it always shows the oil level is at the correct level. Agree/Disagree that the oil leak is from a bad head gasket? Should I pay to have the part replaced, or leave it as is do to the age of the car. I want to keep the car is it gets about 40 miles per gallon. Appreciate your feedback.
