Thanks steelhead2... like I keep saying...any input is welcome.
so the following comes to mind

Can anyone actually explain to me why... if the high pressure oil is leaking...I would not have low pressure oil.
Is it correct that the HPOP is resevoir fed by the low pressure after it goes through the filter?
I should have low pressure if this is the case. I could see the resevoir running empty, the LPOP not keeping up, if there was a big HPOP leak.
The only way I may not make pressure with LPOP is if it was directly ported to the HPOP. My problem remains...no LPOP flow or pressure

Yes npcc partsman, I got the entire front engine cover.

This is an old Ford tech video on oil pressure problems. didn't solve mine but its a good diagnostics video. when it asks... let it run your multi media program

 

upper oil pan to bedplate leak at the pickup port. My daughter could of done better on the finish grind on the mating surface on a bench grinder. Very surprised it lasted 5+ yrs. Parallel thickness differences of .008 didn't let the gasket work. Bed plate straight enough. Had .003 milled off the upper pan...got oil now, just gotta put the rest of it back together

 

That's a helluva find. Thanks for posting back the problem and your solution.

 

before dropping the pan I had better say that we are working on basically the same issue, and in our case we were able to inspect the pick up tube with a borescope and it is in place and intact. we have not found any reason to be experiencing not only no low pressure, but the pump is not even moving any oil at all, this truck came in with no high pressure oil and the low pressure oil was ok, and we found a bad hpop. however, during the course of the repair, we also lost low oil pressure also, and could not find any cause. after repacking the gerotor gears with vasoline,we got the low pressure back, the engine ran, was road tested, returned to the customer, and died going down the road, towed back in with no low pressure again ( at least not on the dash gauge) whic we will of course need to verify. If we solve the issue I will be happy to post it, however the customer is pretty upset, and we may not be the ones to fix the truck, GIVEN THE AMOUNT OF TIME REQUIRED TO REMOVE THE OIL PAN, AND GIVEN THAT IN OUR CASE THE PICK UP TUBE SEEMS TO BE OK, YOU MIGHT TRY TO BORROW A BORE SCOPE, OR GET A
VIDEO INPECTION CAM ( ABOUT A $100 FROM HARBOR FREIGHT) AND TAKE A LOOK.

 

Hey motor junkie....this is old news. A review of the posts will show you that the upper pan was the problem where it mates the bedplate.
Hell, I'm already beyond that and have studded the heads and put in a Bulletproof egr cooler and oil cooler. It's a good thing I love my daughter cause the factory 6.0 is a POS

 

I'm trying to get this video as my truck seem to have a similar problem, but it is not there anymore.

Any help greatly appreciated.

 

speedo9... I copied and pasted the link and went right to it. It is a good video but if you don't have Ford tools, it won't help much.
It'd be better if you had an understanding of the porting of the oil system up from the pan and all the way through.
I could help with that if you tell me what you have done. Once I figured it out, it made much more sense.
Let me know

 

Evidently you need windows media player to view the video.

 

You were right, it works fine and btw, it's a great video. Thanks a lot for the link, it seems very helpful.
As far as the link, I was trying to watch it at work and it seems that my work network prevents me from seeing it. When I got home last night, it opened just fine.

 

If you don't mind my asking, how do you remove the front wear sleeve to slide the inner gerotor gear out? I'd like to replace mine while I have the whole thing torn down.

 

my 2004 f 250 6.0 has a oil pressure problem about 5000 miles ago I replaced the hpop ,IPR,ICP,EBp because i broke it ,egr delete and oil cooler and now i have no oil pressure on the low oil pressure side put a gauge on the oil filter housing holds about 5lbs cranks for ever befor it will start up but after it starts it will idle smooth,pulled gear pump and pulled cover off on marks or scratches to speek of , need help I am stumped

 

If you don't mind me posting here having the same problem
2006 f350 6.0
New lpop egr delete hpop sensor cleaned all other sensors ran ok just nopower replaced lpop it was trashed cover also now no oil pressure at filter will not fill

 

You need to start your own thread so it will get the attention it deserves. That being said having a trashed LPOP gear and cover is bad news as it usually means it ingested a needle bearing from a failed lifter and the short block will need to be removed to replace the damaged cam shaft.
