leaking tranny fluid and oil

[rmb1393]

I have a leak around my rear main seal that runs down the back of my oil pan but its mostly wet and not dripping but its still bothering me. I know the rear main is prone to leaking but im not that sure because the valley of my engine looks pretty darn dirty. Anything I can do to diagnose where its coming from without pulling the motor?

As far as the tranny fluid it is leaking at the front of my transfer case. Same thing its not dripping yet but the fact that its pooling a little is aggravating me. Any help to either issue would be greatly appreciated! Thank you!

The rear main is NOT prone to leaking.
Pulling a motor to diagnose a leak? No sir. There is a thread in the 7.3 tech section about common leaks. You need to clean it all up really good and then see where the leak starts. It o rings somewhere. Either on the high pressure oil lines from the high pressure oil pump to the heads, the 'non serviceable' plug on the back of the HPOP. Or plugs in the high pressure oil rails. Or o rings on the turbo pedestal.

So clean up the valley with degrease or brake cleaner then run it and check again? Thank you for the quick response!

Basically. I wouldn't pressure wash it but soak it in simple green or some solution after getting it wet, then wash it off best you can then see where it's coming from.

Should I wrap wires and relays?

Nah, but I'd let it dry out really good first. I parked mine on a good incline so everything would wash out the weep hole at the back of the valley. Keep the air box dry of course.
I let the engine cool as to not chance a cracked block. I mean ambient temp cool. Then washed it, just not spraying on electrical components very hard. Then let if fully dry.

Thank you! Looking in there now their is a lot of dried up oil around the pedestal and one pf the pedestal mounting bolts seems to be missing.....
