Not Reall a Problem, more like preventative

Hey guys/gals,

I was just wondering how many 7.3 owners change the oil on the upper side of the engine? The powerstrokehelp guy swears by it, but I wanted to get opinions of more people on whether it's worth it or not. Part of me says 700k+ miles on vehicles he must be doing something right, what say you?

I do it, but its hard to get all the oil out. I did this last night during an oil change but idk if I recomnend it. When the injectors fire it spits out the oil used from each injecton into the head, so after draining the oil I cranked it and ran it for a split second, did this a few times and got more oil drain out of the pan

You do realize it's part of the same oil system as the whole truck right? The LPOP feeds the HPOP reservoir, then once the injectors use it, it goes back to the oil pan.
The PSH guy is also a on most things, like this.

Yes, but when you drain your oil, the oil in the hpop and heads still sits there not draining

[jesilvas]

Yea, but a qt, if that. 1/15qts is not a lot at all. Yes, you can do it, but very far from necessary.
If the motor sat a long time, definitely will help in cranking it back up.

agreed, i quit doing that a while ago cuz it took too much time, i leak enough oil im constantly doing an oil change anyway lol

I have talked to many International mechanics and none of them have ever done it to any t444e.

Once you change your oil take it for a 20 min ride. Check the oil then take the Allen out of the hpop stick the dip stick in the hole and see if the hpop oil is the same color as the oil pan oil. It should be if all your pumps working 100% if it's not then change the hpop oil. And you have bigger issues if the oil isn't the same color.

It takes the oil from the hpop a while to drain back into the pan but it's sapose to

I could be wrong but I don't THINK its supposed to drain back into the pan. This would lead to long cranks while the LPOP fills the reservoir back up

It dosent drain into the pan once the engine is shut off. It stays in the res. the oil that is in the res gets picked up and goes through the injectors then once passed through the injectors it's sappose to go back into the pan some how. I don't know the exact way

I think he means it ultimately returns to the pan eventually
