I just bought this truck from Texas. 1995 f250 7.3 4x4 extended cab long box. It has a fuel leak in to the valley on the top of the motor. I took all the covers off and v pipe for the turbo to try and see if I could find anywhere it's coming from but no luck. Any ideas? And on another note it seems like one injector is out or maybe a bad o ring? On drivers side valve cover there us a breather tube going into the intake by the turbo. There us alot of oil or possibly diesel going through that into turbo. Now it could be oil or diesel or mix. I have bad allergies right now and can't smell it but it's black like oil and runny like diesel? Any ideas about any of this would be awesome!

 

Fuel leak could be from a fracture in the fuel bowl or one of the back lines leaking.
Try cleaning it all up and shake some baby powder from the rear of the bowl back to the turbo pedastal. It should leave a tell tale sign easy enough if your have someone at the pedal. that lower tube rising up to the turbo intake is the Doghouse or CCV CrankcaseVentalation. Its common to draw up some oil in the vapors whatnot and get into the turbo. It WILL eat up the flex hose connecting directly to the turbo and it generally fails along the clamp lines. Riff Raff diesel sells a nice replacement. With it off you;ll probably see a small stream/collection of oil just at the base of the wheel and while you're there, inspect the wheel for sideplay (should not) and condition of fins. Dusty fins and your intake it leaking ( look for the 6637 mod, napa filter), dings and dents. Comgrats on the new beast.

 

i would say from the fuel bowl, is your fuel bowl tight? and theres also a fuel line that runs up behind the motor on the OBS fords, id clean it up nice and run it and see if you can watch where its coming from.. is it a fast leak or slow?

 

I do have it all power washed of. I still can't determine it. I am gonna check that line behind the motor today. And also it is a fast leak. As the truck is on its pumping a good sized puddle just after a few seconds of running. Its coming down over the bell housing of the tranny and leaking from there. Thanks a lot guys!

 

does it run fine? i wonder if its a return line because if it was a feed line leaking it would have low fel pressure, and also sucking in air causing it to start hard and run hard or not run at all.. im not a prof. mechanic but i know how to work on my truck haha im just putting in my two cents!

 

It actually does run rough when idling but when you put your foot in it it seems to clear up a bit. And it does also start pretty hard. And thanks a lot!

 

Fuel pump can leak out from its back side inddicating its on its way out or just maybe the fuel intakes at the heads in the rear..got me scratching that you can't see it. BTW, leaking down over the bell housing bit; the valley has a rear weep hole that will take the fluids down that way instead of just sitting there and its helped out by the engine being slightly tilted back anyway.
