Just watched some videos on YouTube from a powerstrokehelp guy, and showed on changing "top end oil". Has anyone seen these or done it? Seems I need to make my own tool to do it, but he said it changes 3 quarts and you had to run it to cycle and shut off, but he never said to change this top end oil after crankcase oil has already been changed, or do change this top end oil before changing the crankcase oil. Any help?He said it's huge on making injectors last...
Changing top end oil??

To the OP,
If you ever want to know anything about the HEUI system on your truck, if you know anybody at a CAT dealer, just ask them, Cat designed it..
As others have already said, the HPO system receives oil from the low pressure lubrication system to the HPOP. At that point, the pressure is stepped up and sent to the injectors. Once it enters the injectors and is used to fire the individual injector, the oil is dumped out of the HPO system via spillports on the injector bodies. It is dumped out ontop of the heads and allowed to return to the engine oil pan, so that it can start the trek again...
Theres alot more going on between the steps above, but thats pretty much the skinny on it.

i have changed the oil from the hpop and noticed your oil from crankcase stays cleaner longer. I think it helps. But every one is different.

You could pull the plug on the back of the heads and drain most of it out. Then run your bats down starting it after an oil change.:doh:

Then drive it on 6 cyl for a hundred miles.
I don't think I could bring myself to go to that extreem. Hell, my lawn mower hasn't had an oil change in 12 yrs. Just add a little once a season. True story.
I'm not convinced that it matters that much. Do you have a blackstone done @ every change also??

What has this site turned into?
Everyone who thinks that changing the HPO is necessary - you need to take a step back and listen to those who have been around this site for alot longer than you. This question has been brought up numerous times over the years, always quoting that Powerstroke douche on Youtube - and every time it gets the same responses.
LISTEN to those who have posted already, by adding comments like this you are further pushing our community backwards with this type of thinking.

Same here only have about 8 years on it but I never change the oil in it. My dad and uncle can't stand it. I just tell them when it craps out, they can have it as an experiment.

That's easy to know.
Stock injectors require 7 gallons of oil to inject 1 gallon of fuel into the engine. So if you are driving 70 MPH and getting 17.5 MPG you are burning 4 gallons of fuel per hour. This means your injectors are using 28 gallons of oil per hour. If the HPOP reservoir held a quart, it holds less than a quart, you would be using it's capacity every 32 seconds.
444-4D Thanks for all that information... I will copy and paste that info into my documents...
But Why is the oil in my crankcase after 2k miles since last oil change... still golden and clear and the oil within my HPOP Very Black and Some what Gritty{feeling the oil between my fingers}... It's seems to me if this oil is cycled through the system that fast... The oil would be the same through out the system...
I guess this is one for the Grey Ghost File.
I know this debate is beyond talking about any longer... But seeing it and feeling it in person...Makes a fella really think something is not working the way it was intended to work...

Changed mine. Took a total of about 20 minutes and a few quarts of oil. It was very thick and looked bad. My question would be why wouldn't you change it? Everyone is talking about mods and other stuff they could put on their truck Why not do this simple thing?

it changes itself as the engine runs... so why bother?
For those wondering about the rate, while I cannot say for sure, I do know that the Cat version of this setup exchanges the oil in the HPOS at a very fast rate....
IF one were so inclined, they could get some dye for engine oil and put it in the HPOS and start the truck....
