HPOP leak

STLstroker · #1 (**permalink**) 03-05-2007, 10:29 AM

i have a 99 f-350 7.3with 133000 on it. i have started a small leak that comes from the top of the motor and through the valley drain hole. it only seems to be coming from the front of the engine and i dont think the turbo pedestal is leaking. Everyone is talking about the oil quick disconnect o-rings. Does anyone have any pictures? Also i have cleaned off the engine valley and can only find oil under the the fuil filter housing or from a possible sensor on the driver side of the HPOP. the sensor is about half way down the fuel filter housing. Any thoughts? How hard is it to change the orings? i miight change those just to see if this is the problem.

Can the hpop be removed to examined or do you have to install while still assembled ont he engine?

there is a 18mm plug on back of hpop , there is a o-ring there also that can leak along with the line fittings

i also forgot to mention i found a broken ring or c clamp of some kind in the valley. it had a rubber coating on it but was broken in half. could this have something to do with it? When i rubbed my hand on the back underneath the hpop is when i felt alor of oil. is that plug in this area?
