Help me identify this oil leak!

Alright i have clarified that this is not leaking from the back of the valve covers downward. My oil level has been depleting a small amount recently and i believe it is from the back of my oil pan gasket. A trans leak from this area doesn't seam too likely. The picture was taken less than 24 hours since i decreased and rinsed the oil pan area. Could some one please help me confirm that my oil pan gasket is the leak shown. Thanks guys!

If you notice a leak coming out of the hole between your rear housing and transmission on the bottom, it might be a rear main seal. Since you said your oil level is going down, I would look real close at the hole to see if it is dripping out of there. Otherwise, it would be the pan gasket. I cannot remember if the rear of the pan gasket is part of the rear main seal too, maybe someone else would know.

the oil is below that pan gasket.... so i doubt it is coming from there. rear main seal is more likley.

make a trip to the local Vautozone and get some oil dye and a black light.... that will show the leak.... tho ya need to change your oil soon afterwards.

I would more and likely say rear main seal leak as well.

Alright guys, Is it worth getting the manual for the 4.7 to do the rear main seal? Could some one please tell me a little more about what doing the real main seal will involve and the best way to go about doing it? The oil leak seams to be pretty concentrated from the 2 holes in the rear housing so by the sounds of it its the main seal. From my understanding i will have to drop the transmission to complete this act, Could some one please explain the best way to complete this repair. from my research i need a special dealership seal puller tool as well as a special dealer ship tool to set the new seal.




pulled the inspection cover and i could see a drop of oil coming off where the crank connects to the flywheel so it MUST be the rear main seal.

THANKS

good luck....

if anything, your pulling the trans, oil pan and flywheel..... worst case, pull motor and put on engine stand....

depends on how the seal goes in....

i have a leak close to that area as well, but mine looks diff being a 5spd. i was also thinking the rear main, but i'm not losing enough oil to worry about right now. it's a very slow leak, but enough to make everything wet under there. i never show low on the dip stick level.
