whats up yall?im about to replace tranny in my garage.so im going to be doing some other maintenace while its out.there is an oil leak coming from the rear drivers side corner of the intake manifold.i cant really tell where its coming from because its so darn tight up there,but it runs down the side of the block right next to the rear corner of the head.i know theres an oil sensor up there,but my mirror seemed to show it being dry.is there anything else i should check.is there anything in that area that could be leaking?thanks in advance.

Oil pressure sensor is most likely, if not that then maybe where the PCV hose connects to the back of the valve cover (pre-01), or valve cover gasket. Really unlikely would be back of valley cover gasket.

could be the oil sender leaking, possibly the valley cover gasket..maybe a valve cover gasket..prolly have a better chance of takin a peek in the area after you get the trans out.

thanks alot for the responses.my assumptions were confirmed.there is not alot of stuff in the rear drivers side corner to be leaking oil.so i basically have 4 places tha could possibly leak.
1.oil sender(most likely)
2.pvc connection
3. valve cover gasket
4.valley pan gasket(unlikey)

is there anything else in that upper rear corner to check?(im not gona be able to fix it till i get tranny out)

Top drivers side part of the rear main seal.

I would change that seal anyway since the tranny is going to be out...its cheap and its crazy fast and easy to change, like 10 minutes.
