Question about 1999 Chevrolet Astro
An oil leak that a mechanic cannot find? Find a new mechanic.
Okay, are you saying this is leaking a quart or more a month? That is a LOT of oil.
Oil does not evaporate. (Okay, yes, oil does evaporate, but so slowly that it is not going to be noticable in a vehicle). That said, the oil is going somewhere.
* Is it leaking on the ground? If so, then the oil will be visible the next day -- somewhere, either on the ground, or on some part of the frame. However, it will be visible.
* Is it a blown headgasket? If so, then the radiator fluid will be oily. Not good.
* Is it leaking into the transmission? Very unlikely, but in some applications is possible (not sure specifically about the 1999 Astro). However, this would be noticable as oil in the transmission.
* Is it blowing past the rings? If so, then the inside of the tailpipe will likely be sooty.
The oil is definitely going somewhere. I'm looking forward to hearing where!
