As a stated in my earlier posts, I am new to the 7.3 Powerstroke. I have an 02 with an oil leak, and after reading other oil leak posts, it has led me to look on top of the engine at the high pressure oil pump area. After cleaning the valley and taking a short drive, sure enough it is coming from the area arounf the high pressure oil pump area and running down and out of the flywheel cover. I went to the Ford dealer and bought the o-ring seal kit for the high press oil pump and installed the rear plug o-ring, but I can clearly see the 2 injector hose fittings are not leaking. I cleaned it up again and took it for another drive, but it is still leaking. It appears it is coming from underneath the high pressure oil pump. Can anyone tell me what else it may be?

 

Some threads to read up on HPOP leaks.

Good luck

 

hey i just fixed my hpop it was doing the same thing i replaces the whole pump it was leaking from underneith some where like the non-serviceable plug. i had the dealer do it cuz they tampred with it and when i got it back it started leaking. i would say if its not the rear plug or the lines buy a new hpop and install. or try to replace the non-serviceable oring i got instruction on how and part #s someone sent them to me i will let u know

 

How expensive is the hpop, and how difficult is it to replace if it comes to that? Thanks Baker on the offer for the non servicable oring install information. I would like to get that info if you don't mind

 

This is how to repair the "non-serviceable" plug on your HPOP

--------------------------------------------------------------------------------


This is how to repair the plug that is on the bottom of the HPOP (the plug that you have to remove the HPOP to get to). This plug is listed in the service manual as "non-serviceable"/"do not remove".

After tracking down the leak on my HPOP, I found it to be the plug on the bottom that is not serviced in any of the kits that I read about. After hearing the horror stories about people trying to repair this leak only to have the threads strip out or the HPOP not build pressure afterwards, I made a trip to the local International dealer. I was able to speak with a very knowledgable service guy that informed me that there is indeed a service kit for this problem. He stated that the DT466 I-6 engine uses a very similar HPOP and there was actually a recall that addressed this issue. The recall was only for the I-6 though so that is why many people wouldn't know about it. He took me back and showed me how to fix the problem and while I was there I picked up the repair kit that has the instructions,new plug, o-ring, and loctite (the kit contains extra parts that aren't used on the 7.3 HPOP). The part # for this kit is 1842906C92. I would scan the instructions but I do not have a scanner, sorry. The instructions basically state that the plug should be heated before removal whch should reduce the chances of stripping out the threads. Also, before any plug is removed, the HPOP should be positioned straight up and down with the machined face down and the snap ring end up so that the "ferry plug check ball" is not disturbed. I hope this helps alot of people that don't want to/can't pony up the money for a new pump.

 

i havent replaced it my self but its not hard. i dident have time to do it and the dealer worked me a deal on the labor but a new pump like 650 and up
