Won't run
Used forum several times and always found answer to my problem. Ran HPOP low on oil 2 times and had to tow home. Have new O-rings and have non-serviceable plug on order. Will install all when it is delivered. HPOP is full of oil but it will not run right. Died again and had to tow home only 2 blocks this time. A little over quarter tank of fuel. Got started again a little bit ago but wouldn't hardly go over 2200 RPM's. Would get to about 2200 RPM's with a steady foot on throttle and RPM's would drop to about 2000 and recover to 2200. When foot taken off throttle would almost die but then would roughly idle. Can anybody help with suggestions

I agree. On the obs trucks there is a relief valve in the oil pressure housing. Idk if the Superdutys have this or not but in the obs's if it comes out the oil will go straight to the pan. Although I've never heard of it happening without the filter being removed

What you're referring to was an issue with the early OBS trucks where the valve was staked in place. I believe late in the OBS run it switched to a snap ring holding it in place. The super duty uses the snap ring too. I've never heard of one of those falling out, but I still stick my finger in the hole to check every time I change my oil. Old habits I guess.

An HPOP oil an inch down from the top? Normal. As for the truck starting after adding the oil, it's more likely your fuel settled "within reach" of the pickup tube and not being sloshed around. I would urge you to fill up the fuel tank, not the HPOP tank... then let us know what that did for you.
