My dad has a 03 6.0 showing no oil pressure on dash and the oil filer housing will not fill at all. Im guessing its a lpop problem but could also be hpop leak. What do you guys think?

What do i need to fix?
well first make sure its the problem, so dig into the hpop.... if its indeed gone, replace pump... or if your good at tappng, tap it and put a plug in it... you could also take out the regulator on front cover, 12mm allan... see if its chewed up or maybe a needle bearing....
drain oil first and see if the ball blocks the drain. also check for other metal... if the filter full of shavings? I doubt it though

No metal in filter. How big is the ball in the pump? Does the ball have to be in the pump if I tap it and plug it?
marble sized. technically, yes the ball has to be in the pump for you build oil pressure!!!!! lol
but no it doesnt when you plug it. I dont think new pumps even have it in it anymore.
dont freak if you cant find the ball... Ive only found two. but make sure you look good

Do I need to pull the oil rail out of both heads to pull the pump?

Pull the geroter gears off and see why it isn't low pressure oil. They might be damaged

:whs: You need to find out why you don't have any low pressure oil. If you don't have any lpo then you won't have any high pressure oil. Chances are you just have a bad lpop and hopefully it didn't eat into the front cover. I would also check and see if the lpop pick up screen wasn't plugged.

pull the lpo regulator first.make sure it didnt get stuck.i bet you need a pump like said above.

Pull the regulator first, make sure it isn't hung open and/or that it doesn't have any foreign debri in it. That will take you about 30 seconds to do, no need to drain the engine oil. If you don't find anything suspect then I would pull the hpop. If it was running fine then just died, I seriously doubt you have a low pressure issue. The regulator is stupid easy to remove to verify there is no lpop concern. I have only found one check ball from a hpop and I can't even tell you how many I've replaced for this exact concern.

Usually yes, all the time no. I would rather pull the regulator and verify that there is no low pressure concern then pull the high pressure pump. Even then, I'd rather pull the gerotor on an early 03, I can have the gerotor out in ten minutes as opposed to pulling the pump in 40 minutes thanks to the stupid crossover.

If the oil filter housing would fill with oil then yes. If he isn't getting oil to the oil filter housing then it isn't making it to the hpop. He has a lpop issue. But that's just my WAG

ive had the geroters go out and no meatal in the oil filter ro houding. sometimes they get indintions but no metal comes apart. cant have high pressure oil without low pressure.
