Hydro Oil filter housing would be fine -- I am thinking you have no or low oil pressure

not good for the crank bearings for sure

Really -- oil pressure and fuel pressure should be required add-on gauges for these trucks

Think Dash Boss is apple compatible

A gauge on that engine oil pressure is the only way to know if you have it or not -- gauge and hose are cheap for testing, zip tie to the wiper arm
like $20 for the cheap kit -- need an adapter for the engine tho - 11x 1.25 metric
I did check the reservoir and it was empty. I have not filled again and started since I’m not in a hurry to go anywhere until the end of the day and the more times I prime this thing means the more oil I need to drain when I do get it started so I don’t have the CC overfilled.

I’m going to get hands on my neighbors snap-on scanner which shows me the live data. I use to have a Samsung tablet that I had torque pro on but they upgraded to iPads and I haven’t gotten the apple compatible ELM. not to mention the torque pro only works on the android platform.

Should I be checking the oil pressure at the HPOP reservoir or is the oil filter housing just as accurate?

snyda88 I went to fire it up this morning and the even though the reservoir was full it started and then stalled. Primed the reservoir again and goosed the pedal once it started and it ran fine all the way to work, 45 minutes for a 30 mile commute on the highway. Once I got to work I shut it off and then went to try to start it again to check and it started and then stalled again. I’m kind of back to square one here. I think I might be pulling the pan and checking the pickup tube this week because I’m reading other posts where people say that even with a low reservoir it shouldn’t matter so long as I have good EOP while cranking because it will fill up the reservoir while cranking. I have a new IPR but have not installed it because I’m not convinced that’s the issue since the whole HPOP system worked fine before I started this project. Am I flawed in my logic??

Yes. oil that low in the reservoir is the HPOP mounting gasket or shaft seal -- there is a stand pipe in the reservoir that keeps oil from draining back down the low pressure system

could also have a leaking injector -- easy way to test that , is remove the oil hoses and place the ends higher than the reservoir -- then fill the reservoir and check the next day -- if the reservoir is still full("3/4" down) -- then reconnect one hose and re-check, then the other hose
I doubt it’s the injectors leaking because before I took on this project it worked just fine. I did notice that after I mounted the HPOP back to the timing cover there was a lot of in and out play on the HPOP drive gear. Not sure if this is normal but I just checked the level again and it’s been 4 hours since I started the truck so got that going for me...

greenskeeper It can take a while to bleed the air from the HPO when opening things up

snyda88 Well, pulled the HPOP and checked the mating gasket, cleaned it and put it back together. Along with making sure the HPOP reservoir gasket properly seated and primed it and fired it up and let her run for about 20 minutes. Shut it off let it sit for 10 minutes and checked to find the reservoir was still sitting at the same level (3/4” below port). It’s now been over 2 hours since I started the truck and the reservoir is still right where it was after I shut the truck off. Fingers crossed it’s still there in the AM. I did have a long crank the last two times I started it but I attribute that to me pulling the HPOP off along with the oil lines and there being air in the system still.

Done with that, waiting on a buddy to drop off longerm16200 bolts to pull it back on. Going to get things put back together and try to crank it again to see if this is the issue if not then it’s time to drop the pan and inspect the pick up tube flange and gasket. Fingers crossed it’s just the seal around the HMB.

I have not messed with swapping the IPR given that it worked fine previously.

Hell, the whole truck ran fine before I decided to undertake this project....
It's the installation of the LPOP. Don't throw parts at a perfectly running truck. The two variables as to why it's now not starting is the LPOP or the oil pickup tube when you did the pan (which is the least likely of the two). Good luck.
I packed the LPOP with Vaseline this time around and she finally got a prime and came to life. EOP on the mechanical gauge on the filter housing read 9-10psi at that point. I did prime the HPOP reservoir too. Had the scanner on it and I was getting good injector pressure at idle. But my IPR duty cycle was high around 65% and up.

I took it for a road test and it seemed just fine. Came home and parked it in the driveway and went about cleaning things up. When I went to fire it back up after sitting for about 20-30 minutes I went to back up and the oil pressure dropped out and I had to prime the reservoir again. Move it shut it off and then started it again and it fired up again.

Went to start it this morning and the reservoir had drained down overnight. Primed the reservoir again and then started it and runs fine.

So I’m getting oil to the reservoir from the LPOP after I prime the reservoir but I don’t know how the reservoir is draining down over night.

Perhaps the bottom reservoir gasket didn’t seat right when I put the reservoir back on after resealing they timing cover???

I have a hard time believing it’s the low pressure oil system. But who knows.
