Warning to 6.0 PSD Owners with Amsoil System

All this discussion of various routings and with and without valves has been too much for my brain to keep track of...

Think of a two parallel tubes drilled in a flat block of aluminum. The machining inside the circular filter gasket mating surface exposes part of the inlet tube to the outside ring of holes of spin-on filter. The bypass filter is first. The oil travels into the filter cans but outside the filter element. It is pushed into the center of the filter where the hollow spin-on fastener provides a return path to the outlet tube. The spring loaded restrictor valve regulates the pressure in the inlet tube. As it is pushed back and provides the full flow filter a larger supply opening the pressure drops and the spring pushes it back. It reaches some equalibrium position. The hole in the center of the plug will always provide at least 25% flow to the full flow filter. The flow through the by-pass filter is completely dependent on the pressure in the inlet supply.
Maybe that helps?

Greg,

If Jim was the original designer of the adapter, isn't he fairly well qualified to recommend removal of the restrictor?

PLEASE NOTE THAT THE ADAPTOR IS NOT THE FILTER HEAD WHERE THE RESTRICTOR IS.

Agreed, but given that Jim has been an Amsoil rep for years, and has direct access to the senior-most techs at Amsoil, to the best of my knowledge, he's the most qualified person so far to make a recommendation.

Herb

That is your choice. I am at "peace" with leaving it in.

If Jim is still following this I would be curious to know if the anti drain flap is a recent improvement to the filters. Maybe the last 2 years. I know that my original filters used to get really hot.

On the reverse flow situation. I sending my oil sample in to Blackstone tomorrow and will post the results when I get it back. I will be able to compare them to 2 other samples (normal with high silicone) but also with reverse flow. I do not believe this 5000 mile sample got any filtering at all.

Herb

Jim is a fine fellow but he has no more access to the tech department than joe blow off the street. You guys suit yourself on this. All I see is no one getting anything in writing on what to do and when the motor takes a crap because the oil system has been modified who do you think is going to pay for it? Has anyone here talked with SMB or Amsoil to get this in writing and if so why is it not in writing. I can tell you why because if it does get put in writing and something happens they will then be responsible and neither SMB or Amsoil wants that. You guys suit yourself but if it was my motor I know what I would do. By the way Jim has been and Amsoil dealer about long as I have. I won't recommend any kind of a change from design on my own that I can tell you.

At least the people who remove the valve still get oil filtering. If the full flow ever clogs up the bypass will start filtering more. This is still a thousand times better than the low / no flow situation I had with the reverse hookup and the very effective anti drain valves in my last filters. At a minimum with removing the valve you should be getting the equivalent of a stock setup. It seems silly to me to modify a system to make it be less effective than what it was designed to do.

Thanks for the Forum, or I would have never found out about this problem. 07,6.0 diesel, built by SMB West, spring of 07. Jim has been great to help me fix the problem.. Mine was wrong also. Droping ALL the amsoil, and filters.. starting with new everything. Remove the sping behind the white oil filter tonight, and reversing the adapter plate lines.. Jim says, "don't change the lines until you put new filters on". What ever is in the filters would be reversed and would flow though the engine. Reverse the lines on the adapter plate and use 7/8 wrench, with TELFON TAPE. Hope this helps someone else.. Gene

MY WISHLIST

1) I would love something in writing from Sportsmobile West on the restrictor issue.

2) I would love something in writing from Amsoil on the restrictor issue.

3) I would love 1) and 2) to be a joint letter/Technical Service Bulletin.

4) I would settle for 1) and 2) to be in agreement.

5) I would love something in writing from Amsoil on the shift from the EA0-26 filter to the Donaldson P553411. Every Amsoil application guide I see still references the EA0-26 filter.

I completely agree with Herb regarding the wish list. I'm still waiting on some kind of finalized recommendation from SMB and/or AMSOIL before I go through the trouble of making all the changes (I only want to do it once). I actually sent Peter an email regarding the restrictor, but never heard back. I have a feeling that SMB is still trying to figure out their position on this.

Gene - that is completely different than what the instruction from AMSOIL recommend. Here is their instructions:

5. Using two 7?8 wrenches, tighten hose fitting swivel nuts and swivel
nuts on angle fittings (if used) to 525-575 inch pounds or from finger tight,
rotate an additional 60° or 1?6 of a turn. Note: Do not use any form of
thread sealant anywhere on the hose or angle fittings.

I tried attaching the PDF, but it was too large (478kb).

Been pipe fitting and using flare fittings for almost 30 years and have never used a sealer on flare fittings. Once in awhile use anti seize and this is a time it should be used.
