oil bypass system

[tmarti96]

I hope this is the correct forum. I am interested in installing an oil bypass system on my 95 Ram. I have checked out Amsoil and Puradyne systems. Anyone know of any more systems that provide good cleaning of the oil? Looks like a TDR member would come up with a simple, inexpensive method. Any help is appreciated.

I have an Amsoil unit for sale-make offer (I used it for a bit and changed my mind and took it off).

homemade bypass oil system

Go to your local Fleetguard distributor (Cummins dealer) and look up a LF 777 oil filter. Fleetguard offers a filter head for this filter.

Add about 10 feet of 3/8 inch hydraulic hose with push on oil fittings. Manufacture a bracket to mount in your choice of locations. (frame along side the transmission is convenient)



Plumb the inlet side of the filter head from a pressurized oil source (tee in at the oil psi sending unit or use the pipe plug on the OEM filter location). Plumb the outlet of the filter head to a non pressurized oil location. (valve cover, top of the crankcase, oil fill tube). (Note - if using other brand filter / filter heads, make sure that the outlet from the bypass filter has a restriction inline to limit the total flow of oil to about 5% of the total engine oil flow volume so as not to starve the engine bearings of necessary oil flow)



Total cost in parts - $75 plus your time.



The LF 777 is available at most truck stops as it is a filter that is used on class 8 trucks. Cost about $15.



Another bypass filter to consider is Oilguard. www.oilguard.com



Good luck.

What kind of oil life extension can you expect with the by-system, or is just keep the oil cleaner running?

And that fleetguard head has the right restriction size hole, right?

thanks

I am running the amsoil, with Bill Kollmer's battery mount and CPFF's block adapter. I was going to remove it until I put in his adapter( had leaking problems with the POS amsoil adapter). It is an excellent addition. I am going to change the oil at 15,000 on the oil this time. I have read that the amount of contaminants decreases with mileage to a point and I just passed 22k. After this first 15k I will go by the analysis.



hope this helps

Fleetguard says the base for the LF777 has too big a hole for the B5. 9 but I haven't heard of anyone having a ploblem. If it were too big, the oil pressure would show it because the sensor taps in well down the side of the engine. The Lf777 is 5 micron. Craig

I have the Amsoil Dual Bypass with CPFF's billet block adaptor, battery mount and braided stainless lines. Without a doubt, this is the best built, heaviest duty setup you will ever find. The block adaptor is a one piece billet part with a heavy duty brass stem, the Teflon lined braided stainless steel lines are pre sized and assembled to work with the battery mount and block adaptor and are rated at 2,000psi.

And the battery mount is absolutley beautiful, automotive gloss black paint, super heavy duty and mounts around the battery tray, it does not interfere or touch the battery in any way. Amsoil's filter mount is also billet aluminum, black anodised. CPFF is also an Amsoil dealer so you can get everything you need from him, it will take less then an hour to install. Anybody who has seen this setup i am sure will agree. Very resonably priced too.

Goober,



The Oilguard filter is either a 1 or 3 micron rated filter and has the proper restriction in it (I have one on my truck). Being very conservative, using this filter will allow a 25,000 oil drain interval with a high performance oil such as Royal Purple. This drain interval couls be extended well past this if desired but I'm happy being able to run this long. The goal is to get better protection for the engine and to simplify maintenance.



The Fleetguard LF777 head will not affect your oil supply even though Cummins says not to use it in a 5. 9 B series (Craig S. ) (They also used to say that the Cummins Premium Blue 2000 would not work in a B Series engine so take with a grain of salt what the factory says. I've owned a B Series powered vehicle for 11. 5 years now. I've alos put industrial B Series parts on my engines that the factory said would not work - had an 89 without a tach and retrofitted one from an industrial engine off of the timing gear with a right angle drive adapter) It's a filter. How would the filter know what engine it was on? As long as you place a restriction in the outlet to limit flow so that you do not divert an excessive amount of oil flow from the main gun rail (bearing oil supply) you will be fine.



This auxillary filter should allow you to run say 25,000 miles on the LF777. I would recommend that you continue to change the 'full flow' filter at 5K or so.



As far as extending your oil change intervals, that is dependent on which oil you are using, how much fuel, dirt, water, and soot buildup you get into your oil (ie engine operating conditions). In general, the cleaner you keep your oil, the better (longer) you would be able to run any oil safely and the better wear protection you will get for the engine.

Thanks.

There's a plug to the left of the oil line going to the turbo off the head of the stock filter housing.

Is that the plug tha can be used for the supply line?

Yes, that is the port most folks use. I mounted my bypass filter horizontally on the back side of the crossmember under the radiator.

 

[Barry]

Ah so... ... but where do you plug in the return line???

 

[redram]

Return line goes to any unpressurized oil location, ie the valve covers, top of the oil pan, the oil fill tube, etc.



On my system, I removed the 12V one piece decorative plate over the six individual valve covers, replaced the number one valve cover with an industrial version that has an oil fill port (same size as the stock oil fill tube on the timing case) and modified the cap to accept a right angle AN fitting that I attached the return hose to.

Is the turbo return line pressurized???

 

[wakely]

Sorry all - I sold my Amsoil bypass kit.

Thanks to all for your interest.

Amsoil Dual Remote Bypass

I am using the Amsoil Dual Remote Bypass system with the CPFF billet block adapter and a custom designed/fabricated filter adapter (mounted to the frame crossmember). Additionally, I made up a set of Aeroquip Teflon/braided stainless steel supply/return hoses using Aeroquip steel fittings. Custom modified aluminum Earls hose separators add a finishing touch to my system.



Unlike EMDDIESEL's CPFF block adapter retention nut, my older version is made of steel, which was 100% turned/milled and subsequently blued (if memory serves)... at any rate, it is not made of brass. [EMDDIESEL, I assume by "brass stem" you mean the center retention nut however, if you mean the side or bottom hose adapter fittings, they should be made of steel that are plated with a zinc dicromate finish]



I really like my bypass system... maintenance has been greatly simplified (especially with my Air Bulldog induction components in the way of a "normal" filter change.

Hey John,



When you made up your hoses, did you go with -8 or -10 ends and fittings. I'm doing the same thing and am struggling with that decision. My Amsoil Dual Bypass block is tricked out to accept Fleetguard Stratapore filters as the full flow filter, BTW.



Thanks in advance,



Todd

Todd, How did kyou get the filter head to accept the Fleetguard filter? I want to add a dual filter setup tomy 95 Ram 3500 but hate to pay for those expensive amsoil full flow filters. thanks.
