Oil Leak under the turbo on top of the valley baffle
I have a 1994 Ford F-350 Turbo Diesel 7.3L crew. I overheated the truck and now a oil leak splattered on the firewall. I looked at the source when engine was running and found oil seeping up out of a down warn directed pipe that enter to top of valley baffle under/behind turbo.
My question is what is this problem and how can i repair it ?

Ok ive experienced this same problem, my dad has the same year truck as u.first year powerstroke, you have to remove the turbo, there will be one bolt in the turbo stand, u will need a 10mm universal joint for a 1/4 inch drive ratchet, to remove it, but under the turbo stang there will be 2 O rings, replace those and u will be set to go.

Most oil leaks on this engine occur in the valley of the engine at the back of the oil pump. If you look directly down into the center of the engine infront of the turbo you will see the back of the pump and the potential leaks at the plugs on the pump and the output lines to the heads.
How many miles on the truck? Replace the air filter.Check all aftercooler lines for air leaks.Check your turbo to be sure the seal is not leaking causing the engine to **** oil thru the turbo. You may need to clean the fuel system.Add 32 oz of Power Service 911 to your fuel. If none of this helps and you have a high mileage truck it may be time to replace the injectors
Oil cooler on the 7.3 turbo-diesel 1994 is located on the left side of the engine block just under exchaust manafold , on the rear end of cooler you have a oil filter . This is steel tube with many small tubes inside for engine coolant. I just replace on my truck.
The fuel pump is located under the turbo on that truck. It is most likley washing sediment/old fluids out of the vally of toyr engine. It is also driven by a push rod that ths cam drives, so the lower pump o-ring may be leaking too. You can change the fuel pump without pulling the turbo. Good Luck
MY 2001 7.3 was leaking the same way. The dealer said the o'rings under the pedestal were leaking. I had the dealer replace the o'rings. By the time I got home, it was leaking again. Called the service department and told the manager,and they put on a new pedestal and o'rings. They only charged me half price for the pedestal and no labor. That did stop the leaks.
The HPOP (high pressure oil pump) is right under the filter housing. There are 2 lines that distribute the oil to the cylinder heads. The o-rings on those fittings go out. Kit is available from Ford or International. You will need a special wrench to get to the fittings though.
