Oil leak? :(

I think my car is leaking oil.  This is my third car and I've never had this problem with the other cars I had.  Can anyone tell me what I should do?  Loccating it?  I'll probably get it fixed at a shop.  How much U think it will cost?

if you're engine bay is clean it should be easy, just find the spot that has a bunch of black gunk on it, and trace it back to the source

if its not a bad leak than you could prob. put the engien leak stop stuff in with the oil.

How do u know its leaking oil?  Do u visibly see oil? If so where?

your filter, or plug could be loose, or one time i (but i dont think it was) was accused of driving over the curb leaving my driveway and smashing the filter on my moms van its was loosing all the oil in like 2 days

talkin 'bout leaking oil, the bolt on the valve cover of my car is leaking oil, between the 1st 2 cylinders and the last 2 cylindrs, i have no idea wha's the torque to put on these guys, anybody have an idea? 'cause i tightened one of my car before not knowing the torque to put it it, the bolt broke... and so i got rid of that car...
