Remote bypass oil filtration

[jick.cejoco]

there have been a misleading terminology or confusion over this thread. the bypass component is inside the cartridge spin on type oil filter. the bypass allows dirty oil to lubricate the engine once the filter element gets fully clogged up or if the engine demand for the oil is more than the filter could allow. since the 1950's, the lubrication system evolved from the drip type to splash type to the forced type with "catch-as-can type" filtration to the forced full flow filtration. all the oil going into the oil galleries must flow from the pump to the full flow filter save the ones coming out of the bypass. the system that have been mentioned over and over throughout this thread is not bypass type or system but a remotely mounted oil filter mounting or location for ease of service.

It has been discussed already that Remote Bypass Filtration is a different thing from bypass-valve.
Bypass valve in some cases are built-in the vehicle's spin-on adapter, but most are integrated in the oil filter.

My system for my vehicle is a bypass set up, I have a restrictor in the threaded nipple that reduces flow to the second filter so it does not recieve full flow just like the amsoil set up.

I basically copied the system from a guy who posted how to do a budget set up, Not paying 300USD for a amsoil kit.

Basic set up
Dual filter remote oil filter kit
Modified filter nipple (3/4-16 1-1/4" long with 1/16" orifice)
So I have one full flow and one partial flow filter. My partial flow is the Fleetguard Stratapore media the best filtration you can get period and a high efficiency synthetic media filter.

The nipple modification consists of:
- tapping the ID of one of the supplied nipples with a 1/2-20
- take a 1/2-20 steel bolt and thread ~1/2" of it into the nipple
- saw off the part of the bolt sticking out of the nipple
- cut a groove across the face of the bolt sticking out of the nipple
- drill a 1/16" hole through the center of the bolt
- using a blade screwdriver, turn the bolt until it is just below the lip of the nipple
- tig the bolt piece in place (carefully)
- this is the nipple that you will install the by-pass filter onto.

So mine is a true bypass system not just a dual remote filter set up, which by the way works very well if you use the same set up I have even without the bypass mod. And will extend your oil change intervals big time. There is more than just one way to make these set up's You can also do this with a single filter using a oil cooler. Amsoil is way overpriced and you can make your own for far cheaper.






This is the set up I copied to a T, except I used way better filters.


This thread started out as one thing but has spread to basically be a very good discussion on filtration in general. And I think one of the most helpfull threads for routine maintenance for vehicles.

We have covered the parts of a filter in detail including the bypass valve, filter media's, levels of filtration and efficeincy as well ass fuel filtration and even air filters. It's kind of a jack of all trades thread on filtration. And one of the biggies, FAKES and there are plenty in the Philippines.

The thread should be changed to Bypass filters, Oil filters, fuel filters and air filters

Just to add, the setup above is the same with this. Return line going to sump is the same as the intake of the spin-on adapter.



[SIZE=2]And just to add more readings to clarify things (from cummins pdf)[/SIZE]

[SIZE=3]Diesel Engines generally use one of two types of lube filtration systems:[/SIZE]
[SIZE=3]��A Full Flowsystem[/SIZE]

[SIZE=3]��A Bypassor Part Flowsystem[/SIZE]
[SIZE=3]　[/SIZE]

[SIZE=3]��A Full Flow system works the way it sounds. The entire flow of the fluid (oil, fuel, etc.) passes through the filter on its way to the engine[/SIZE]

[SIZE=3]��Full Flow systems are common in lube, fuel, and air systems[/SIZE]
[SIZE=3]　[/SIZE]

[SIZE=3]��In lube systems, the full flow filter is by necessity an open filter[/SIZE]
[SIZE=3]��The full flow filter cannot restrict oil flow[/SIZE]

[SIZE=3]��Used to control larger particles, the full flow filter cleans all of the oil going to the engine[/SIZE]
[SIZE=3]　[/SIZE]

[SIZE=3]��A bypass or part flow system has a different flow path than a full flow[/SIZE]
[SIZE=3]��In a bypass system, a small amount of flow, usually controlled by an orifice, is taken from the main flow stream[/SIZE]

[SIZE=3]��That oil is passed through a filter and then returns to the sump[/SIZE]
[SIZE=3]　[/SIZE]

[SIZE=3]��Due to the lower flow of a bypass system, a bypass filter can remove smaller particles[/SIZE]

[SIZE=3]��Bypass systems are common in cooling systems or in conjunction with a full flow filter in lube systems[/SIZE]

Hi, after reading through this thread, decided to try fleetguard filters. Bought some today at Prudential Intertrade at east service road, bicutan paranaque. An LF3462 for my mazda 323 1.3li and supposedly a LF3403 full flow and LF3523 bypass for the R2 2.2li. diesel engine rocsta jeep.The guy gave me a donaldson P550162, said it was the replacement for the 3403, but the LF3523 bypass they had made me doubt its authenticity, it had only the filter mouth covered with plastic, no "made in u.s.a" mark, and the fleetguard name in red not black, decided not to get it. The LF3462 was P260. and the donaldson P550162 was P225.

With those price, it may indeed be fakes. Dapat at least high 300's or 400's for those sizes eh.

The Donaldson was made in mexico and checking thru their website it was indeed made in mexico, also upon further checking it is identical to the LF3462 in specs and applications which I also got from them. The filters look authentic, their not the expensive microglass type just the cellulose ones and the guy said they were not fast moving stocks so maybe they still have the old prices on their stock inventory.

The Fleetguard filters name can be in red or black, But no country of origin = fake period some are made in other countries like France. Plastic covering only the bottom of the filter = fake only china knockoff's will be like that.
