First thing that came to mind is was it an OEM oil cooler/kit? Thinking of all the problems others have had with Dorman. I guess pulling IPR to look for signs of green gasket material might answer that question.
Not sure on the Oil cooler, the invoice has no part numbers, only reads "6.0 oil cooler kit- updated (includes updated stainless screen)" sale price was $455.47 plus tax before labor if that gives any indication.
I just got home from work and intend to hit this hard tomorrow. I've read about doing the air test, is it something worth trying if I have limited diesel experience? I'm afraid if I take it to a tech. They will insist on diagnosing from the beginning and in turn charging me a lot of money. I hope this isn't a sign of things to come with my new to me 6.0, I knew maintenance would be my biggest concern that's why I paid a higher price for what appeared to be a well maintained truck.
I would pull the ipr. Screen is most likely pushed in. Even if it isn't, take the screen off of the end, push the brass plunger under the screen with a 1/4" screwdriver and flush with brake clean and then compressed air. Reinstall and try it. Screens are available separately. I have had ipr trouble on both of my 6.0s. Only 1 time out of 4 was the screen pushed in and broke.
If I pull the IPR do I need to drain oil first so it doesn't spill everywhere? Or, is it high enough to where its above any standing oil? Another thing I've noticed, with my truck being on an incline, is my coolant almost seems to be pressurized even though its cold. The coolant reseviour is way above the cold mark, again this in on an incline at this point.
If your on an incline, nose down, you will appear to have to much coolant. Flat surface is when you want to check all your fluids. You won't make much of mess at all if you pull the ipr without draining any oil.
I figured nose down would be high coolant level, by incline I meant nose up. I am going to push onto road this weekend to get new readings, thanks for taking time to reply, I really appreciate it.
No worry about much oil coming out if you remove the IPR.
Also even if you do take it to someone I would still do all the
diagnostics I could to make sure that who ever I take it to
is not giving me a line of BS thinking that they have a new cash cow. Seems to happen all too ofter
with new owners. We don't want this to happen to anyone.
Almost like a truth test. If you have an idea and they come
back and say it needs a engine you know to walk out and go
somewhere else for any service.

EDIT : I just looked to see where you are. How much of a rush are you in? I
an in Spanaway but won't be able to get loose till later next week. Also do you have a compressor?

I appreciate it, I'm going to work on it this weekend. I have a compressor and a fair selection of tools, if I come into serious problems I might be sending you a message. Spanaway is a couple hours away from here I believe.
Pulled fuel filter at top to inspect and decided to change for good measure, went down to parts store and when I came back the bowl was empty even though I had set the lid back in place ( not tight though) is this normal? Or is a possible symptom of my problem?
Watching as we are having similar problems with matching numbers. New/Rebuilt IPR is suspect but partner wants new HPOP. His money but I think rebuilt IPR is problem. We cannot get it to close and the old IPR would not close either.
BigGreenEx,
If could be normal drain back into the tank.
Air in the housing could allow the fuel to drain
if it had a temp change or an air leak.
I don't think I would worry about it.
One thing you can do is turn on the key and fill
the housing without a filter in it. Then use the
wire over by the A/C box to crank the starter
and see if you get any bubbles. This is how you do
a bubble test.
This is the wire I am talking about. Just tap it onto the + post
of the battery and the starter will crank over.
Mtnsammy,
As already said. Did you have an oil cooler done?
One could be just bad practices and lack of proper
cleaning of the system during the changeout or two
it could be a Dorman Green gasket that is falling apart
and plugging the screen on the IPR of even blowing
the screen into the IPR and hanging things open.
I have ordered an IPR socket and electronic control for pressure testing HPO system and IPR, it should be here Wednesday. I already have the truck pulled apart, so it should go quick once its here.
One question I had was about the green Dorman gaskets, if they are a known problem, has the company done anything to remedy it? And if so, when did that change take place?
Someone said that they did but I don't have a clue
how many hoops they had to jump through.
You could make a new thread asking about Dorman Green
Oil Cooler Gaskets. Then maybe someone that has had to
deal with that mess can tell you the details.

You can search some of the threads about Dorman oil coolers and see that Dorman was replacing the gaskets with a new style and compensating companies for the failures. I don't know what the process is that you have to go through but it was occurring.
Removed the intake, degas bottle, FICM, and brackets. Disconnected the wiring to the last three injectors and removed the last valve cover bolt. I have pretty good access to the IPR at this point, watched a video on YouTube about half way through so I didn't mess up the FICM connections, wish I would have watched it at the beginning, it would have cut it down to a 30 minute job.
