Trying To Prime The Engine After Install?

Hey guys,

Trying to my truck going again and I'm a bit rusty on what is and isnt normal with the truck behavior.

I had the engine out of my F250 for a basic reseal and a few quick repairs before I begin using the truck on a daily basis again.

I just got the engine back and did not prime it beyond filling up the HPOP reservoir. I know it takes a while to get going but at this point I'm beginning to have doubts.

When the engine is turning over, I'm not seeing any pressure build on my factory oil pressure gauge. Also, with key on my oil temp light is on.

The fuel bowl is full and I can hear the pump priming.

The truck started up fine before the motor was pulled so i'm trying to verify my work before I suspect any components failed.

Im also without any scan tool at this time which is hilarious because its all in my F350, in Arizona.

Thanks in advance for the help.

Get a booster charger on it. Disconnect the 42 pin connector, crank it over in 30 second intervals, cooling the starter between tries....do that maybe 4-5 times, connect the 42 and crank some more. There is a fuse for the PCM, but I don't recall the number.

May I ask the benefit of disconnecting the 42 pin?

It keeps the injectors from firing without oil being present.

You could fill the oil rails by hand, top off the HPOP, check fuel bowl to ensure it is filling, check IPR for damage, etc...

I topped off the HPOP and turned it over a few times. The level was going down. I tried it a few more times before deciding to put a charger on the truck for the night.

Its pouring rain here so I gave up for the night.

If the HPOP reservour drained down, should I be worried its a LPOP issue? Im still hoping im dealing with a lot of air but this is the first time I've had this much of an issue.

Well, I left the batteries on a charger Friday afternoon and gave it a try on Saturday morning.

Filled up the HPOP reservoir one more time and got a bit of smoke out the exhaust.

Got all excited and gave it another turn.

Started and shut off immediately.

Heard a leak. Oil under the truck.

Blew the line right out of the HPOP.


So Monday we shop for anyone who will take my HPOP as a core with blown out threads.

A lil FlexSeal will fix that right up

If you don't wanna go that route I'd think a Heli-Coil or similar repair would be effective.

I have heard that they do heli-coil them but how do you keep metal chips from getting into the HPOP during the process? I never did a heli-coil job.

Packing grease around the tap will help capture the metal chips, but can't guarantee it will capture 100%.

Use a scrap of paper or bit of rag to seal the bore of the HPOP below the threads then use grease on the tap to capture the chips while threading it. Do it in small steps, turn the tap a quarter turn then back it a bit before turning it another quarter or so, cut a thread or two, back out tap and clean, grease tap and repeat. Use plenty of grease to fill the tap each time. When through extract the paper or rag and look for bits that may have got by you. Some Helicoils have a drive bar that breaks off when it is fully installed, if that is what you have be sure to plug the bore once more with paper or a rag scrap to catch the piece if it comes off the installation tool. If the coil requires you to drill out the original hole before threading use the same procedure to seal the bore and fill the flutes of the drill bit with grease, drill a little at a time. It's not rocket science just take your time, patience and a six pack will work every time.

What you described above is exactly what I was thinking, but didn't have enough time at the moment to go into that level of detail. Thanks for closing the gaps I left wide open!!

When I met Lewis50 in person, I found out he has a lot of relevant experience in this area.

Great advice for future readers and Quick444 alike.

Thank you for the advice on repairing the threads.

I got in touch with CNC Fab, from whom I bought a new pump last year for my F350 rebuild.

They said my HPOP with blown threads would be no problem as they sleeve them to prevent future issues.

Under that logic and the fact that my truck is going on 18 neglected years of life, I figured she deserved a treat.

I'm hoping to get her back into daily duty again. I got start paying up for all the years I let her sit on the side of the road.
