hi.

i am the recent new owner of 1996 f250 7.3L
135k miles auto 2wd. florida truck.

i have a small oil leak dripoping from the center of the torque connverter/flywheel cover. im belieleving the leak to be coming from what im guessing is a rear main seal? am i correct in thinking this?

how hard is it to do this? would i unbot the tranny and jack up the tranny to get outa the way or is it more invoilved than that?

this is my first time owning a big diesel. my wife drives a TDI jetta and ive driven E350 and F450 at my previous jobs for long times.

any ideas aprecciated. thanks

It could also be your turbo galley seals leaking. When they leak the oil flows to that area so double check. I'm just having that problem with my truck.

 

I have the same problem: a small oil leak dripoping from the center of the torque connverter/flywheel cover, I had double check and it seems that comes from de rear and right corner of the pan, but I really dont know if the leak is coming from the rear main seal.

any ideas?

 

I had the same leak. It turned out to be the fuel pump going bad in the valley.

 

Dry the valley out with paper towels and a long screwdriver. Start it up and check fuel pump weep hole. Its under pump use small inspection mirror. Also if pump is not leaking check plugs in HP oil rail on ends of heads, also could be o rings on turbo pedistal. Everything seems to run down back of engine and indicate a rear seal which is usually not the problem. Jeep1947

 

The hole in the pump is about 1/16th ", at the bottom on the passenger side. It could also be the hoses, the fuel filter, the vacumn switch, the seals on the lines going to the heads, or the banjo bolts.

 

I had all of the above leaks, did the rear main seal, pedistal O rings, and a few O rings on the head. Stays dry most of the time but when I pull my 5er on a real hard hill it will leak some out on the ground. Its a mistery to me. I'll dry up the valley and then it won't leak. I can't figure it out.

 

Like mentioned above did you check the fuel pump?

make sure its engine oil first. if engine oil it is probably coming from up top and running down.
fuel leaks will wash down the valley pan and pick up dirt and some oil on the way to the bottom.
the main seals are pretty tuff on the engines and do require lots of labor to replace them.
I'd look at the topside first to determine the starting point of the leak. There are crossover lines, turbo pedastal seals to look at first.
