Oil leak

I have looked through almost every thread i could about oil leaks and haven't come up with anything. The oil is coming out of the inspection plate on the tranny and a weep hole above the starter. The valley is dry. This isn't a bad leak at all a few drips overnight, it really isn't a big deal, but driving me crazy. My question is: is it possible that the oil galley plug is leaking even though it doesn't feel oily? Or is it possible that the fuel line going into the back of the head is leaking and looks like oil? Any other ideas?

Re: Oil leak

Sounds like,(if im understanding right) that your rear main oil seal is leaking.

Re: Oil leak

Well it could either be the rear main seal, or possibly one of those big plugs in the oil rail in the head. Those are the only two i can think of that would give oil in the area described w/o oil in the valley.

Re: Oil leak

I am almost positive that it is not the rear main seal. The majority of the oil looks like it comes down through a hole along side of the starter where it can go right into the inspection cover. The back of the motor is dry when i take the inspection cover off. So that leads me to believe that it is coming from up top somewhere, but i wanted to know if the oil galley plug were leaking would you be able to feel oil around it?

Re: Oil leak

Make sure you check valve cover bolts the rear passenger side closest to the fire wall can be a bugger to get snugged down. Also check the rear passenger large plug in the HP oil rail facing the firewall. I bet it's the later as they are common leakers...so fire up the truck take a flashlight crawl under there with it running and have a look for the weep.

If it's leaking you will need to replace the O-ring from ford iirc the plug is like 2" in diameter and takes a 3/8' drive extension to get it loose. Might have to pull the down pipe too to give you room...

Re: Oil leak

If it were the oil galley plug wouldn't it feel oily around it? On my dad's truck the one on the back passenger side went bad and it just poured out of it, the o-ring had a chunk missing though. We had that one fixed by a shop and it wasn't that cheap. I am by no means a mechanic or trying to be one, but I am just trying to learn as i go.

It might feel oily but don't forget it's on the vertical plane and if not leaking that much and will only be when the engine is running (start of a larger leak). If you have an aftermarket two piece down pipe on it you can do it yourself with extensions and ratchet, pretty straight forward to do. If you have the stocker DP would be time to change that out as it's a POS pipe anyways..... as suggested fire it up get under there with a bright light to inspect...

Re: Oil leak

I just changed the pedistal this last week to a deleted one. I think that was part of the oil leak i had. Thanks anyway.
