I did look at it. Thanks for the information! I printed it. Here are some excerpts.

Discription & operation Aw crap! I will return after 9pm To finish! so hold on to your saddle. I shall return!

Um... Back.

Section 1: 7.3l Power Stroke (Second page of the PDF you posted)
Electronic Engine control Subsystems Sample page

Description Of Operation
Starting from the third paragraph third line
"... One feeds leaves the check ball and enters the front cover. from there it enters the high-pressure oil reservoir. the second feed exits the check ball and enters the left bank valve lifter oil gallery". (which sets up the next excerpt. Rustin)

Starting form the fourth paragraph third line.
"... The valve lifter oil gallery supplies pressurized oil to the valve tappets and to the piston cooling jets. oil from the valves tappets is routed upward to the cylinder head valve train through hollow push rods...." This does not help your argument the oil in the valves is not from the HPOS part 23 on components list is what you were referring to. Rustin

Second page
High Pressure Oil System Explanation
first paragraph
"During initial start or Cold Start, the high-pressure oil pump receives unfiltered oil from the left side valve lifter gallery through the anti-drain back check valve." (Makes me want to keep doing my procedure after all. Good grief man. Rustin) (This part might help your argument, just a little. Rustin) Once the engine starts or during warm engine starts, the check ball closes and the high pressure oil pump receives filtered oil from the high-pressure oil reservoir. (This helps your argument just a little but not by much. Rustin)

Second paragraph
The high-pressure oil pump pumps the oil under extremely high pressures (4,115-20577 kPa [600-3000 psi] through the left and right side high-pressure supply hoses to thhigh pressure oil rails (integral to the cylinder heads). Once in the oil rail, oil is fed to the fuel injector bores through oil feed galleries (4) drilled and machined in the cylinder heads. the high pressure oil then actuates the fuel injectors.(in the High pressure oil system components Graphic it shows the oil entering and leaving the injectors. this is after the injection process is done. I did not say it was a closed loop system Read my posts. I said it dead heads. The entire essay did not say it returns from the injector. I still maintain that the oil leaving the High Pressure Oil System does not fully return. reason being the orifice from the injector is to small to let out enough oil for a full return after the injection process (I maintain that it poorly circulates). this is from experience of working on a powerstroke. It is called a design flaw. you know what a design flaw is? Rustin)

CSIPD I am sure your a knowledgeable guy and you know allot through experience. I am sure you would take the shirt off your back to help somebody in the right situation. When I am wrong. I am wrong. this is a case of arguing about apples and oranges. these are our opinions. you know what opinions are? they are every where. I thank you for the PDF. I feel that your argument is solid. However; after reading it. I am really going to continue the extra procedure in my oil change. from what I have read this did not help you to convince me otherwise. thank you for a good debate over a stupid opinion. We agree to disagree. you could have said that you disagree from the start.
Thank you
Your friend

Here is a couple videos (since everything on the internets has to be trues...)



Watch the amount of oil that is coming out that access point in just this short video... That is because as the HPO Res is filled, it overflows and goes back into the pan. Now remember this is at idle and about 25psi oil pressure. Now increase that oil volume by about 2/3's when at WOT... There is some volume there...


Here is a second one to chew on... Watch the amount of oil coming out of the spout... Doesnt seem like a very closed loop system...

Now when you respond, learn to use the quote button above, rather then just reply in my response...

 

A true Closed loop system does receive some oil from some where. have you ever seen a closed loop hydrostatic drive system, any closed loop systems? Have you studied hydraulics? We can start a whole new thread on that argument!

Wow... You truely are that dense... Thats one injector... x8 and thats alot of oil.

Try this... Remove the plug from the top of the HPO Res and crank the truck... Matter of fact, just let her run...

Should pump out about 10-12qts and then the truck will die... BECAUSE YOUVE RUN OUT OF OIL...

 

No doubt do you have to Shout! That's where I pull the old oil from. of course there is pressure there! where does it come from?

LOL! I am dense. your the one keeping the argument alive! LOL I just disagree from my experience. Obviously you disagree from your experience.

 

Your experience is based on what you read on a YouTube post... What you read on a forum...

Mine is based on over a million miles of seat time, over 13 years of wrenching on these trucks, Hundreds of hours of research, and thousands and thousands of dollars spent...


I've been there, done that... You've seen this, read that...

 

I think the oil system moves alot of oil I have my reservoir off right now I'll take some pics ....beautiful paint on the motor wish mine was that clean

 

Thanks.

 

For 26 years that I worked as a mech tech we used delo 400

I put it in a toyota corlloa drove it for 100,000 miles and pulled it down for inspection.

wear was non detectable.

I like it

 

I am not dispelling your character or your knowledge. it was a good debate over an opinion. You have really not read any of my posts. you just took at as an attack. Have a good evening.
