04 6.0 hpop question

[CYates73]

Ok so my brother in law has an 04 6.0 and he has 117k miles, he's heard that the hpop goes out between 120k-130k, like clock work, any ideas?? He is worried about it and I'm not sure what to tell him

I wouldn't say clockwork. My truck is an '05 and the HPOP went out at 98,000.

Seen them go a lot sooner and seen them make it 200k.

If he wants to see if its starting to go tell him to air test high pressure oil system. close off ipr valve and remove oil filter and listen for gurgling in oil filter housing if there is even a little bit the hpop is bad! it should be silent!

juger can you expand on that process

Make a test harness with a new IPR pigtail. Disconnect original harness from IPR valve and plug in new harness. Remove ICP sensor from passenger side valve cover and remove oil filter. Not sure which one is ground, but ground one side of harness and apply 12v to the other which will close IPR. Apply minimum of 100 psi air into ICP port and listen for air coming from filter housing.

Thanks for the info I will pass it on to him

Lol what he said !!!!! Nice it's on off / duty cycled solenoid so it doesn't matter how you hook it batt just don't leave it hooked up longer than min at a time!

[Steve6L]

So there should be 0 air coming through? I don't get how this tests your hpop seems as if it only tests the solenoid? What do you guys use to fit an air hose to the valve cover?

If I understand this correctly (Dale can correct me), you're not testing the solenoid. You're using battery power the IPR to hold hold it closed. You have to put an air fitting in the location where the ICP sensor goes and attach the air hose to that. The pigtail is merely to power to the IPR closed. When done troubleshooting, you put the ICP back where it goes and you put the original harness back on the IPR.

Is that correct Dale or dhanna6powerstroke??
