A guy that I work with just got a 7.3. He was telling me about changing the oil in the HPOP system. According to him when you change the oil, just dropping the plug and filter still leaves about 3 quarts in the HPOP system. He told me that you can pull a plug near the fuel filter housing and use a pump to suck this oil out. He also claims that he had a noticeable power gain after doing this.

I searched the forums but couldn't find anything. Can someone shed some light on this please.

Some change it and a lot more don't change it. In my opinion there is no need to change it due to the fact that it circulates with the oil in the pan and there is no way that you would get 3 quarts out of the HPOP.

The 3 quarts comes from the capacity of the HPOP reservoir and the oil galleries in each head. 3 quarts may be a little high, but close. This oil is not drained during a normal oil change. The idea of sucking it out of the HPOP reservoir has been around and the dude on Powerstrokehelp.com has shown it in his video series.

Yes you can do it, and I have done it. The fallacy of it is you can really only get the oil out of the reservoir. The oil in the heads is pretty much stuck in the engine as it will get pumped back down into the block anyway. So if you drain the reservoir and add fresh oil, you can then crank the engine and run it. The oil in the reservoir will get pumped into the heads and the oil in the heads will get pushed to the pan. You have now reliable way of capturing all the old oil anyway.

If you are concerned with having clean oil, I suggest one of two simple methods. One is change your oil every 3,000 miles religiously. The other is install a by-pass oil filtration system. Either way your oil will be cleaner and you will not have to worry about the un-drained oil causing any issues. I used to change my oil every 3k and my oil always stayed cleaner. I now use by-pass filtration and my oil after 3k is clear with just a hint of color. I can tell the by-pass filter is making a much better difference than changing the HPOP reservoir oil ever did.

The oil in the HPOP is not different from the oil in LPOP, it is the same oil that cycles though the engine. LPOP provides the oil to the HPOP, just how can it be different? I watched that video from Powerstrokehelp.com and am skeptical of the video testimonial evidence that the HPOP oil is so dirty that getting it out will add centain "longevity" to the engine. I am also skeptical that the product recommended for everything from oil treatment to transfer case treatment, "Prolong", is anything but snake oil. That company was recently sued and injoined from making more false claims or comparisons to their compeditors, when you are good you don't have to make claims. Try the tried and true method to add longevity don't let someone in flip flops changing a PSD hub influence you into a largely useless procedure. Probably more chance that you will introduce debris into the HPOP during the procedure than it will help add "longevity". Just change your engine oil on a regular basis, 3000 miles is a little early but what the heck go for it. Get a good air filtration system like an Ford AIS, get a periodic oil analysis and that will be a good indicator of FACTS on how your engine is doing.

I have taken the Powerstrokehelp.com 7.3 Master mechanic course and it is a great course. It pains me that he pushes a snake oil product like Prolong because it calls into question the rest of his instructions which by and large are excellent. If you watch closely, you will see that he tempers the HPOP oil change by saying that he works on a lot of fleet trucks that get poor maintenance and this is where he sees a difference by doing this. If you change your oil on a regular basis, this is something you would probably never "have" to do. And yes, you do leave dirty oil behind and there is no way to get it all out no matter what.

Spend your money on a by pass oil filtration system and it will be money better spent in the long run.

If you do on his site he says to add prolong. I DONT ! Ive been doing this service for a while. While I make no claims. I did notice a difference. Some say it hogwash and some say it works. You'll just have to be the judge for yourself. I use a pump that I have to change the oil for my boat. Tube fits perfect inside the hole.
And to put the oil back in I just use NEW cap I had laying arount from a gear lube bottle. It screws right on the rotella oil 1qt bottle. Works like a charm.

Is this an actual system you installed or an off the shelf bypass type filter? I have been using the International LF9027, am I getting true bypass filtration?

EDIT: I just saw your other reply with a link to your system, very nice. I still wonder however if I am accomplishing the same thing with an off the shelf bypass filter, although I will say they are quite pricey. It that the advantage of your system, more ecomomical?

 

[woodnthings8]

I built mine based off of other systems. The off the shelf systems were too much money! The filter is a small micron filter and that works well as a by-pass filter. Putting everything together was pretty easy and proved out affordable. The hoses cost the most, but I wanted it mounted in a safe location.

That part I understand, but I was asking about an off the shelf bypass filter not an off the shelf system. Just a throw away spin on filter like the LF9027

 

[woodnthings8]

Guess I missed that. Running a filter like that may help. I went the route of a separate filter because the filters are widely available. I also am one that has a hard time believing that one product can effectively do two tasks efficiently, being it is a fleetgaurd product I am sure it is good though.

Thanks for the responses. I've had this truck for over 5 years, and 100,000 miles. I have always changed the oil between 4000 & 5000 miles. I'm not overly concerned about this procedure, I think the important thing is changing the oil regularly.

Just to clarify, the oil that is in the HPOP sytems does circulate with the rest of the oil? The guy that told me about this made it sound like the oil in the HPOP was stuck in there and did not circulate through the entire motor.

3 quarts or less of old oil, being mixed in and circulating with almost 4 gal of new oil, dosen't seem like to big a concern to me.

 

[woodnthings8]

Yes, the oil is circulated through the whole oil system! The injectors use the oil at a ratio of 7:1, 7 parts oil for every part of fuel. So, if you burn 10 gallons of fuel, you would cycle through 70 gallons of oil through the injectors alone!

 

[DirtyWhiteBoy]

Thanks.

I checked the oil in the HPOP after a couple days following an oil change just to see if it remained black & dirty. It looked as clear and clean as the new oil in the pan.
