my wifes 00 malibu suppose to have 2 oil leaks on the main seals. but the funny thing is it has never used any oil. could this leak been sealed by the oil buildup? or just a place trying to get some more money? I am going to prob use auto rx in the car and take care of this possible leak. safe than sorry right? It just seems wierd that theres a leak on the motor but never used any oil.
