Burning oil...

[GToddyT5]

My car is burning oil through the exhaust, but not much. What are normally the main causes? Is there really any way to tell without getting into the motor? Car has about 82000 mi on it.

There could be a few causes I know of:

1. PCV valve sticking - cheapest possibility. $3.00 to replace.
2. Bad piston rings - have a compression check done.
3. Valvetrain - valve seals, guides, etc - rebuild heads.

Off the top of my head, those are the main causes I can think of.

I agree with what Jay said. Those are the main causes. What kind of motor oil are you using anyway ?

I was going to suggest high mileage, but Mobil 1 is some pretty good stuff.
