Okay, so i have a 97 powerstroke with an oil leak in the valley, I have already had the turbo off, gutted the ebp valve and sealed it, new o-rings in the pedistal on the top and the bottom and i still have an oil leak in the valley, to me it doesnt look like it is coming from the HPOP. How much oil would leak if the fuel pump o-ring is bad? There is no pressureized oil going to the fuel pump is there? It just looks to me like that is where it is leaking, but I dont know how much one would leak there. And no, there is no fuel in the oil there ether, the fuel pump is working well and not leaking fuel.

thanks for the response.

 

Usually oil will leak from a plug in the back section of the hpop. The oring goes bad. You can use a mirror to check the plug for leak while engine is running. Theres also a fitting under the pump youd have to take pump off to repair.
