    oil leaking :( from where?

    I cant get my car on jacks tonight, but i looked under my car and i have a slow drip coming from around the oil pan. As i cant get under it tonight, im not sure if its not the oil pan. If its not, where could it drip to make its way onto the oil pan?

    Just about everywhere unfortunately. Trace the drip up the oil pan to it's place of origin. If it's on the sides, valve cover gaskets may have taken a crap, if it's in the rear, it could be a rear main, front could be camshaft seals which would be a real problem because oil can and will deteriorate the timing belt.

    well i just had my rear main replaced not even 6 months ago, so hopefully thats not it.
    I think its on the backside of the oil, toward the rear of the car, or on the sides... i will go see what i can in the dark.

    Edit:
    Alright so Its on the back side of the oil pan. The back oil pan bolts are wet with oil, and so are the bolts that are on the steel metal bracket that connect the frames. (the bracket right under the steering stuff).

    If the valve covers are where i think, above the spark plugs, then thats dry.

    The simplest answer is the oil drain plug crush washer. When this leaks the oil tends to smear and spread toward the back as the air pressure forces it backward when the car moves at speed.

    After that the options get more complex. This stuff happens though, so when you have enough light and can safely have a very close look, see what you can find.

    i dont have a washer on my oil bolt, but the bolt is tight, and not over tightened. I think it is a leak somewhere else.

    I looked at what i can find, and thats all the information i have.

    The previous poster that mentioned the oil drain plug possibly being a source of an oil leak was right on the money.

    I change my own oil on my 05 wrx. I have had to add about a 1/2 to a full quart of oil every 2 weeks or so. I thought I was using oil since I drive my car kinda hard. ( it is fun to drive ya know ).

    I have a nice wet spot on my garage floor......oil mixed with a/c water condensation. I originally thought this was all water, until I felt how oily it was.

    Then I got underneath the car and saw the problem right away. My drain plug had a small drip. The leak was probably greater when the oil pressure was high while driving.

    I recall having a crush washer on my drain plug. So I got my rachet set out, my 17mm socket and a pipe I use for extra torque leverage......sure enough, the drain plug needed more torquing down on the plug bolt. I'm going to check periodically and see if that solved my leak problem.

    If you dont have a crush washer, maybe you should consider adding one to your drain bolt. That might just solve your problem, or at least eliminate that from the list.

    Be careful, I have seen many, many stripped oil pans...the torque spec is only like 30 ft lbs...
