Oil galley ports, and bypass filter

[Shamp]

I plan to install an Amsoil bypass filter. The generic place to install them is off the filter housing. I would like to install it so it gets its supply from the main oil galley/rifle. I just think it would look better and more profetional that way. I don't think it would cause any kind of oil flow/pressure problems anymore than if it were at the filter houseing. Here is a flow diagram and I would like to know if anyone knows of a problem or can see a problem that I cant see. Also I will be putting a real oil pressure gauge in the galley also. I know some of the large cummins use "S. T. O. R. M" straight thread o ring metric fittings and was wondering what type thread the ports are in the galley.

If I were going to use the main oil rifle to extract oil I'd want to minimize the amount I take out there. And since I'm paranoid, I'd take it from the end of the line, not the beginning.

The threads on the oil ports along the rifle are M10x1 straight thread. They use socket head screws with o-rings. You'll want a fitting with an o-ring on it - anything else leaks (I know by experience).

The factory oil pressure switch, which is mounted near the main rifle, is M14x1. 5.

I am taking my oil pressure feed from the main galley above the ECM with a M10x1 fitting.

Both the main galley and filter head are after the pressure regulator, but when you take oil from the filter head you are not effecting the flow where it's used.

I am not sure 1 GPM is enough to harm anything, but Cummins put the ports on the filter head for a reason...

i agree with ah64id

If the BY-PASS is from Amsoil, the restrictor is in the return side of the mount. This restriction only allows about 6 quarts of oil per five minutes at 40 PSI to flow thru the BY-PASS element.

Correct me if i am wrong, but as I understand hydraulics which is what the oil circuit is. A pump creates flow. Restriction to flow is what creates pressure. The bypass filter housing will lessen the overall system restriction however insignificant it may or may not be. So if the bypass supply is at the filter head or at the galley it will affect oil pressure exactly the same. If i understand correctly, and I mean if, oil will reach all components in the engine because that would be path of least resistance and all components will then become pressurized at the same moment. Or mostly the same moment.

It is the amsoil filter head with the restrictor inside. Thank you amsoilman, how much it flowed was a question I had but forgot i had it. Less than a quart a minute is not much to worry about.

When I installed my FS2500 (I know its different) but I remember the instructions specifically said to NOT TAP a main oil galley use the port on top of the OEM filter housing. I believe it was something to do with where the FS got its oil to be filtered, not so much as if it would take oil out of the loop. I will see if I can find the instructions for the install.

I take it your using the old style oil press. gauge just a single line to the gauge? so really your not taking any oil out of the system its just filling the tube and the gauge is registering the pressure ?

I think the port on the filter head is primarily for being easy to connect to for troubleshooting. As the galley ports would be quite difficult to get to say in a boat, or excavator. Haveing multiple ports in the main oil rifle would seem to me like they want you to, or expect you to connect there.

Maybe they said not to tap into main oil rifle is because in the kit they provide a pipe fitting and not the proper fitting for the oil rifle?

 

[BIGNASTY]

It could be any of many reasons but I think it was because of where it got it's oil to filter. I have talked to those folks at filtration solutions when I reordered some filters. They asked what I thought of the system, I like it it's built like a tank have friends that have them on class 8 trucks and run oil for extended periods of time. But it would be of interest to me to find out also why? I was thinking is the oil coming OUT of that OEM port filtered or not? If it is indeed filtered it would be filtered as a higher Micron rating that the FS filters, so if that thinking is correct my Donaldson ELF filter filters the oil and then the FS would filter it to a finer degree and returned to the motor via a oil return line that I have on my Rocker cover above #6 I thank you for letting me run off on this I kind of want to know, The reason for the KIND OF want to know is that I have ran oil samples on every oil change on the truck with the exception of the first. I drove it off the lott and took it home and put the FS on, The oil samples have ALL BEEN EXELENT suggest changing filters and continue running the oil, I DONT I CHANGE MY OIL and get the missed dirt OUT OF MY MOTOR Its my call and with a 130K on the truck it has NEVER HAD ANY KIND OF HIC-UP AT ALL WITH THE MOTOR.

I would say that the port's in the main galley are there for the various ECM's and applications requirements for oil psi senders.

I take it your using the old style oil press. gauge just a single line to the gauge? so really your not taking any oil out of the system its just filling the tube and the gauge is registering the pressure ?

I am using an electric gauge, but same theory. No oil leaves the system, just goes to a pressure transducer.

Here''s my setup I came from the top of my oil filter plug

 

[amsoilman]

This is how I have mine setup... ... The filter is on the passenger side behind the bumper. It is mounted on a bracket that is located on the body mount. The inner fender well has been removed for clarity.

 

[mfurrh55]

I made my own bracket to attach the filter bracket to, seems it out of the way and works fine,Monte
