leaking oil like the exxon valdez!

[mattjones]

hey guys so ive come across a pesky oil leak that was little but is now pretty big. its coming from somewhere on the passenger side towards the rear of the motor. ive replaced the valve cover gasket and checked the dipstick tube to make sure it didnt push out or something. but so much oil is leaking that its burning off my passenger side header where it meets the y pipe. my vacuum lines are capped off but there is a breather on it. what do you guys think? rear main seal? is there an oil cooler line somewhere around there? any help is greatly apreciated

There's 2 sensors on the back of the motor, The cam sensor and the oil pressure sensor. Check both, my Yukon is leaking from the oil pressure sensor where the plug goes.

Pretty common for the oil pressure sending unit to leak. I'd check there first, I've done a few now.
