HPOP LEAKING

[Nate Figueroa]

So I though that Had a Bad lpop back in October after I rebuilt my Powerstroke Which is an 03 6.0. It would start and then stall after running 5-20 minutes. Tested the Lpop with a screwdriver and have good low pressure. Gauge reads good too. Now that its cold up here the truck starts and runs fine when the oil is thick. Once it warms up it stalls an will not restart. There is a small amount of oil dripping down on both sides of the bell housing. Im now certain I have a hpop leak. Now the question is how do I test this. The pump must be good if its running the truck. This has the early oil rails. The braided tubes going into the up pipe into the branch tube. Is it leaking at the injectors? Branch tube? up pipes or the two allen plugs on the rail? Im now certain this is my problem.

I work at a Ford dealer and we see the two allen plugs on the front of the oil rail go bad quite a bit. They will cause a no start when warmed up because the o-rings blow out. The o-rings when cold are hard and seal a little better but once warmed up and the oil thins out, it causes a high pressure oil leak. Easiest was we check is we made an air fitting to screw into the ICP hole. We apply shop air to it and you will hear the leak most of the time without taking the valve covers off, but sometimes you need to. And if it does turn out to be the plug, replace both sides because the other will go out sooner or later. Not sure if thats your problem but just saying we see it a lot.

Hey thanks man, Figure its internal. I'm gonna pressure test it like you said. IPR and ICP are dry. Once I tear it down I'll post my findings.
