New leak?

Well I fixed the fuel leak in the valley, no more leaks there, but now I have noticed a leak from the back of the engine, and the oil (It looks like dirty oil ) is running down between the starter and tranny, it comes from outside of the cover of the torque converter not from inside, at first I thougt was the remaning fuel from the valley, but has passed several weeks and it leaks a few drops in a week (not my daily driver) when sitting and it is darker than the other time. I have checked the vc gaskets and the oil gallery plug in the back of the head, they are ok and the valley remanins like a bone, it seems to come from the rear part of the pan, I dont think it is the rear main seal, : any ideas where thats coming from ?

Look ,(if you can ) at the back of the head where the oil galley plugs are ,,O rings tend to go bad there..

Thanks Rick but as I satated that the vc gaskets and the oil galley plug in the back of the head, they are ok and the valley remanins like a bone. I have read that that TC cover sometimes erosions the pan, Ill check that.

ok, I also reviewed the turbo and no leaks, so pretty sure (if its not the corrosion in the pan) it will be the real main seal, and I think I going to live with that leak until some tranny issue comes on and change it. Thanks again, I m going to wait for another inputs, maybe some others chime in.

Don't want to be a smart azz but are you sure the valley is dry, there a some pretty deep holes in there that can hold a lot of fluid unless you're doing wheelies

Try parking the truck on a steep incline or raise it up as high as you can with a jack and flush out valley with a cleaner or water. IF you find it's a rear main leak there are some additives for the oil that will slow it dowm a bit.

Thanks Jim, I will try that, but Im pretty sure the valley is dry, anyway Ill do it. If I add some additive it hurt any thing else or I also can try it at the same time?. The oil has almost 3000 miles and I was planning to change it in that mileage, so maybe Ill wait till then to add the additive, what do you think?
