Engine/Transmission (1998.5 - 2002) Amsoil By-pass system.

[JohnBoy5]

I am looking at putting the by-pass system on my truck. i have read and see a few youtube videos on the 3rd gen trucks having oil pressure problems with the bypass system installed. do we have that issue on the 2nd gen with a 24 valve? if you have a system on your truck how do you like it?



Also i am going to get my truck in the 500 to 600 hp range is this a good idea to get the by-pass system and extend the changes? will i be able to or will the oil reports come back bad... .



i plan to put twin turbos on. just a little more info for yall.

the amsoil dual filter mount is the one that gave the problem. this was a very bad idea. stay with the lf16035 main filter and use a bypass filter of your choice. i run a fleet of dodges and have bypass filters on all of them. i have five different type mainly because i make them out of scrap parts or from a junk yard. the amsol single i think is a bmk21 and the filter is 110 i run two of them. i run more of the class 8 truck style filters because i have to stock them anyway, (they all come from the factory with them). the filters do not have a bypass built in them like the main filter has to have therefore you can run them until the clog up. this is the point that it filters its very best. at oil drain interval just feel of the filter and if it is still hot it is ok. the big truck filters hold between two and three quarts of oil and i do not like that much used oil left in. so i remove the filter, drain and replace. there is about 1,000,000 or more trucks out there running lf777 fleetguard filters and because of this the filters are very inexpensive. the wix # is 51749 the base is 89750 i think this is car quest # but will cross to others. the orifice is to large on the base for our trucks (the big trucks hold 44 quarts) and you have to make a smaller one. i make mine in the fitting that i screw into the top of the stock filter housing. i plug it up with a soldered in piece of shim stock and drill a 0. 032" hole in it. i return most back through the filler cap. some to the valve cover and a few to a second turbo drain. for you, you will need this port for the second turbo. use hydraulic hose and do not mount any filter on a bracket from the motor. there is a cross brace on the bed on the passenger side that i mount most of mine on. we test the oil on each series truck to set the oil change interval. the 04. 5 up trucks has the lowest mileage drain interval of any previous truck. on these it is a must to run a bypass filter. and for those i recommend a luber finer lfp9750 and a lmb451 base. the high price of the amsoil compared to the lf777 is the reason you will probably go with the lf777. on your truck i think you will find it only extends the drain interval by the % of extra oil the filter takes. i think it will be about 20,000 miles.

 

[JohnBoy5]

are you saying dont run any part of the amsoil filter setup or jsut the dual? i was going to get the dual so when i put the twin turbos on it would be easy to change them... what problem did it give you on your 2nd gen 24 valves?

 

[BillGotthelf]

No he is saying DO NOT USE the dual system. That is the bypass filter and a relocated main filter. You CAN USE the single bypass filter system. The work very well and allow for extended drain intervals. If you send off your oil and have it tested every 15,000 miles or so you might never have to change it.

 

[JohnBoy5]

what system should i use? i want to move the filter from the stock location if they have a system that is safe to use like that... when i have twin turbos on it will be a little less work to get to the filters if they are moved... .

[JohnBoy5]

thats a nice install but it will not work when i install the twin turbos. The supply port that you are getting the oil from supplies the 2nd turbo with its oil, also the filter is still in the factory location. if i am able to somehow remove the filter from the factory location i will not have to take the intake system on the twin turbos apart to just get to the filter.



Just a question does it really matter what side of the truck the dual guard is mounted to? i noticed you made reference to that.

 

[CUMMINZ]

JB, use the same install location as I did. Use the remote adapter and route the oil lines across the engine to where I mounted the remote twin filter block. That side of the engine is much cooler than the turbo side.

i have not been around twins very much so this may be a dumb question. but the filter you should be using is a lf16035 that has flutes on it. i do not have any 2ond generations in my yard this morning to look but i thought you could change from underneath. if you can not then i would make up a remote filter mount and place it on the driver side. but use a filter base that will use the lf16035. it will not hurt to place a t in the port that feeds the 2ond turbo for the bypass filter and mount it on the passenger side near the cab on the bed brace. i have a spare filter adapter that i got from summit i do not see a number on it but if you can not find it let me know. i may never use this one. if you can not find a base i would make one from a wix 24770 this has four ports on it with a 1"-14 thread. the lf16035 has a 1"-14 thread. the insert unscrews and i think the threads on it is 3/4 -16 i make my own on a lathe in about 5 minutes but a machine shop should not charge very much. you can use the 2ond input port for the bypass filter oil supply

 

[CKelley1]

oops the lf16035 has a 1"16 thread. did not read before sending

i use the filter LF3894. I have not been able to change it from under the truck because of 2 lines that run right under the filter that are only about an inch from it. i think its either A/C lines for trans cooler lines. i dont remember. Also as for the T on the filter port i would rather not. there will be a lot of doe tied up in the twin turbos and they have oil berings in them so a lack of oil pressure could be a very bad thing. i will look in to these filter adapters also. if i can get the amsoil stuff and have it work properly i think thats the way i might go. of not i will look in to just moving it like you are saying and if i still cant come up with somthing i will jsut leave it like it is and take the turbo piping off every time i change the oil..... but thats a last resort because it sounds like a pain to me.....

OK, now I am scarred s^itless... ... . I have been running an AMSOIL Dual by-pass system on my 1999 for over 10 years with no problems (other than the outrageous price for filters. ) I just put the BD twin turbos on. AM I to understand that my second turbo is not getting oil? If so how long do they last because it has been running this way for a month now. When I took the adapter off off it looked like it was open enough to feed both tubes. IF this was a problem wouldn't the manufactures of the twins tell you that a different oil filtration system was needed. Someone enlighten me before i pass out here. This has got me very nervous.

no, no, no, i am sure it is. how do you have the oil lines installed? if you have it installed with a T it might not be getting enough oil pressure. if you install the filter i would think that pressure woudl drop going to the trubo. . but if you installed them how BD says to one line going right to the first turbo then another to the second turbo with out any t fitting i would think you are ok. you can only flow so much oil through a 1/8th port.

 

[Harlacher]

I have it installed the way BD said to instill them one line to each turbo, with one drain line from each turbo.

 

[JohnBoy5]

then you should be ok. the way ckelly1 was saying to install the bypass system would make me a little nervous if it were on my truck. but he might also know something that we dont know. I try and listen to every on here and the pick the best thing for my truck.

 

[Harlacher]

I sent you the pictures by PM if they are not good enough let me know and I will get more. This is absolutely the first time I have heard of any problem with the bypass filtration system. I got mine 10 years ago and just spent $125 on new lines when I put the twins on.

 

[JohnBoy5]

i dont think its a problem with the twins or the bypass system as long as its installed properly. i did see your pictures and looks like you did it the way i would want mine done.

 

[CKelley1]

the T fitting i agree is not as good as the taping of the intake on the remote main filter. but the amsoil and the home made bypass use a 0. 032"orifice to restrict flow. it will not reduce any pressure or volume to the second turbo. the lf16035 is a lot better filter than the one you are using. harlacher do not worry about your set up. the way the amsoil dual filter mount works is the full flow filter is in parallel with the bypass filter, the bypass filter is highly restrictive so to get oil to flow through it they placed a spring valve in the line to the full flow filter. i took one apart and it feels like it restricts about 5 to 7 lbs. i consider this a very pp unexceptable design. the cr engines do not have the reserve capacity oil pumps like the old most likely because the cr needs more oil for the piston cooling scheme and the extra restriction of the dual mount is to much. i took the dual mount and tapped and plugged the spring channel, drilled a hole between the two to turn it from parallel to series and cut new insert's on the lathe for 1-14 thread and now have a very nice looking fuel filter i use 33374 primary and a 33674 secondary

 

[Harlacher]

WOuld I be better off running without it?

 

[JohnBoy5]

you are good with how you have it setup, you have the amsoil filter adapter and the turbos plumed like bd wants. There should be no oil pressure difference they way you have it vs the stock filter.
