Just noticed a fair size pool of oil where my cars sits in the garage. Was hoping it was from my gfs Explorer from when she had it parked in their over the week but to no avail. <p>From what i can see, which isnt much, it is leaking on the passenger side of the engine. It is all over my cv boot, wheel well, rim and all over the frame. It looks like it is coming from behind the timing cover somewhere. I am guessing it is some sort of seal???
