    Crankcase Oil Leak

    I was a bit tired when I got my oil changed, so I may have misheard my mechanic, but supposedly I've got an oil leak coming from my crankcase.

    It doesn't deplete me of oil between changes, because I drive a fairly large amount, and he said it may be a seal that's leaking. How expensive is this to fix, and do I need to fix it right now so long as I keep my oil levels high enough?

    I know I sound like a complete moron, so be easy on me please :P

    If you have an ecotec its more than likely going to be a front engine seal(really easy to do) or a rear engine seal(more difficult, gotta pull of trans.

    Did he give you anymore details or just say "crankcase oil leak" thats a pretty broad statement.

    How low on the stick are you before changes. Most all 4 cylinder engines will burn oil during operation and the oil does break down over time.

    Do you notice oil leaking under your car?

    If you've got at least 4.5->5 quarts just before you get your next oil change I really don't believe its anything to worry about.
    Car sold, and gone away. Just have the 05 cavi now.

    Yeah, I've got an Ecotec.

    I think he said it was the at the front end, so probably a front engine seal then? I know you can't diagnose things over the internet, but from what I'm telling you, it seems like that, right?

    I've still got a decent amount of oil when I go to get it changed, the only reason he noticed I think is because I had some oil somewhere it wasn't supposed to be.

    I figure it's not a big deal, but I hate having things wrong with my car.

    Considering how knowledgeable I am about cars (read: not), I highly doubt I'd do it on my own. Hell, it'd be a stretch for me to change out spark plugs. The only thing I've ever done is my brakes, and an intake. >.>

    I'd love to start doing more things on my own, but I need/want somebody there to help me out so I don't screw something up. But if by some odd chance I end up getting it fixed by somebody I know, or I end up doing it, I'll write it up for here.

    My cavalier had a crank case oil leak whenever I bought it as well.

    I was lazy and bought some stop leak stuff for oil leaks and changed the oil and put the stop leak oil stuff in with the oil and I haven't had a leak since. It's been about a year.

    I forget what exactly I bought but it worked for my leak.

    Just as an FYI acceptable oil consumption is 1 quart in 2000miles for vehicles with less than 36000 miles. So if youre a quart low after 3000 miles, theres technically nothing wrong

    Lets assume there truly is a leak though. the most common places are the front and rear crankshaft seals. the front timing cover seal is also an area that like to leak from time to time. Make sure you get a detailed diagnosis as to what is actually leaking before you authorize any repairs
    I know stuff about ECOTECS
