I have a nasty oil leak and I have no idea where its coming from. I was letting the gf drive the car for a while. When I get the car to do some work on it there is oil every where. My y-pipe is nasty and it has ran all the way back to my cat. I can't see where its coming from. Are there any common places oil leaks come from??? I just need some feed back. Thanks in advance.

 

Most common place is the oil pressure sensor. It's right next to the oil filter and if it leaks it usually coats the bottom of your car with oil.

 

thanks, how do I fix that???

 

Look at where it's coming from before you change the pressure sender.
