I have had an oil leak for the past few months. I am adding 2-3 quarts every 3-4 days!! thank God for that yellow oil light!! also, it's smoking pretty bad too, which leads me to believe that the oil is leaking onto the exhaust or something else hot and burning off. A friend said it sounds like I have bad cam seals. The smoke is coming from the accessory side of the motor. Luckilly, I have been keeping an eye on it. What should I do?
