Anatomy of a Frantz toilet paper bypass oil filter

[Gary - K7GLD]

Gary,



Does the kit from wefilterit come with everything less the return swivel?



IE all the correct treaded fittings and plumbing pieces?



Thanks

YUP!

If there is enough interest then I will go through the formal TDR process.

I have been out of the loop. There are a lot of pages to re- read... A couple of quick questions though... and I would go in on the group purchase:



1)... Is this a whole kit without needing outside parts?



2)... It does fit 3G truck?



3)... What about the effect on factory warranty by installation of this kit. I am NOT my own warranty station. I have only 12K on the truck and do not want to jeopardize my coverage. Granted, I am convinced it does the engine good, but regardless of the benefits will a dealer welch on coverage in the event of an internal part malfunction?



EDIT:

4)... what was the approx cost back in a day.



(sorry... i only use my office computer and have not had the time to go back thorugh the many pages, but hopfully these Q's will benefit all who are interested. )

I'm sure that Gary will chime in there as well but from what I have learned so far.



1. Yes complete kit except the swivel attachement needed to return the filtered oil through the cap, and a new oil filler cap if you don't want to use your factory one.



2. I looked at my 3rd gen truck and it has the plug to remove just like the pics of the previous trucks.



3. I too am not my own warranty station with only 6k on my truck. I don't think this would void the warranty but who knows what the dealer might do. If I had a major issue seems I could pull the filter off in less than 30 minutes (ie just replug hole and put on original oil filler cap and you are stock. I have NO bombs on my truck but this seems to be a good idea. My oil is always black, I don't care if I just changed it.



4. I think they paid $110 plust $10 shipping. Sent an e-mail to the filter company to inquire what the price would be on a group purchase now. They asked me how many people so I don' t know yet.



Again, if about 5 people chime in and they are priced ok, I'll start the formal process before doing anything... ...

I'm in if it'll fit a 3rd gen... doesn't matter the brand as long as it does it's job.



How much do filters cost BTW?? I know the Franz uses TP... what about the others??

[steved]

One question I had is that I'm reading the Frantz needs to be changed every 2500 miles... this might be a problem because I travel crosscountry... wouldn't want to be stopping halfway to change the filter out... how do you know when the filter needs changed??? Or is this the recommended mileage? What does it hurt (if anything) if the filter gets plugged?



I was also reading about the spinner II, that's too much BS to deal with... and looked at the cartridge style filters like the Amsoil... $230 for the kit and $45 for the filters that don't seem to do the job the Frantz does... the idea of a cartridge is appealing since you simply unscrew one and screw another on...



What other options are there?? I looked at a Gulf Coast filter on eBay (similar to a Frantz)... then the motor guards...



Any word about a group buy??



steved

 

[DaveK98]

As I see it if the Frantz was to get "plugged" it would be no big deal as where you tap in to get the oil line is currently plugged.



I like that fact that the "filters" are less than a buck ie tp. If you are the kind of person that doesn't change their own oil then this is probably not the setup for you.



Right now I've got one other person intersested besides me on a Frantz. Looks like the cost will be in the $165 range or so but this would lnclude the amsoil swivel. Or you could just buy it from wefilterit.com on your own and use the tdr name and only pay about 10-20$ bucks more than a group buy. You could also buy it on e-bay for around $100 but you are getting the old design, and may need to buy fittings and the amsoil swivel or equivliant... .

 

[steved]

I'm pricing components right now... I think the $165 range is about right... here is what I was thinking:



Check Valve (upstream... to hold residual backpressure and prevent low pressure at idle) - $15

Baldwin BT8509-MPG Filter (6 micron absolute hydraulic filter) - $50

Filter head (Fleetguard) - guessing around $30

Hose and misc fittings - around $75



Total of $170 more or less. The Balwin is a spin on hydraulic filter that is basically a cross referenced Fleetguard HF6607 (look familiar? It's a FASS filter!)



So if the group buy doesn't come through... probably buy my own stuff and build it. Some of it I already have... the filters and the checkvalve. I would also probably install this similar to the FASS, only on the passenger side of the truck. That way I could tell when the oil filter was plugging off... it wouldn't get warm and there would be reduced/no flow at the oil filler cap.



So if the group buy doesn't happen, I'm not going to be that sad...



I would also assume the same would be true with the Frantz... it should show signs of plugging by reduced output at the filler cap correct?? It should plug, and not simply pass dirt?

The 2500 mile bit is probably reasonably accurate in day to day around town and short haul usage - but you can certainly increase that interval on longer open road mileage where steady speeds over longer miles greatly reduce lube contamination.



I find that substantial power mods and short trips will greatly increase engine lube contamination and soot levels - and since moving up here to eastern Oregon, adding lots of engine mods, and FAR shorter driving trips, my oil gets lots dirtier, lots faster than it used to - I'm afraid my days of clear oil on the dipstick at 5000 miles on the oil are long past! :-laf :-laf



That said, all the improved oil cleaning benefits provided by bypass oil filtering ARE still there, just less visually evident - and as said above in another post, if the TP element in the Frantz, or other elements in competing brands get clogged, all that happens is that they no longer are filtering, and regular full flow filtering continues as in a stock engine until the dirty bypass filter is serviced.



For the Frantz in particular, extra element canisters run about $25, and on long RV trips lasting weeks or more, I carry a spare loaded canister that I can change at any time in less than a minute, then clean and refill the used one at my leisure.



No big deal...

 

[steved]

I was more concerned about whether the engine had enough oil pressure to push the TP through the filter if it became plugged... not about stopping the flow of oil.

Not likely - never heard of it happening, or seen the slightest indication of it happening in my own setups over a 50 year period...

Guys, Didn't see enough intrest or $$$ benefit to get a group buy going. I just bought my Frants from the guy selling them on e-gay. $100 plus $10 for shipping.



He has 20+ more just like the one I got. I'm sure I'm going to need some extra parts, I'll keep track and post what I needed for my install on my 3rd gen.



Anyone that installed one of these on a 3rd gen do you know what size the thread is that goes into the fresh oil or intake on the oil filter housing (on the top)?

 

[steved]

Guess I'll either buy an Amsoil Bypass or build my own setup.

The thread size on the top of the filter housing is 1/8 NPT. Just remove the existing plug, and install your fitting.

Did you guys use any tefflon tape or this other "stuff" that was supplied on your threads?



Wayne, does the part you mentioned include the 90degree fitting or do I add that seperate and where can I buy it ie you, website etc!



Thanks again!

Well, all the fittings comes in the Amsoil kit. If you are not using the Amsoil by-pass kit, then you can go to an Auto parts store and get one. Just ask for a 1/8 NPT 90 degree "street elbow". If you use tefflon tape, don't put more than 3-4 wraps on the fittings. Or you could use trhead sealant.

Guys - be VERY careful about the Frantz setups from Ebay - the Frantz is made for many different applications, and some of them do NOT have the supply side restriction orifice supplied or installed, so it's possible to see far greater bypass flow than desired in our Cummins usage - just a heads up...



It's easy enough to fabricate your own restriction orifice - I installed mine in the Frantz now on my truck (it didn't come with one) by soldering a solid plug in the fitting attached down at the oil takeoff point at the stock oil filter housing, then drilling it with a 1/8 bit - some prefer 1/16 - whatever you choose.

 

[DaveK98]

Gary, I had wondered about this. So I SHOULD be using the restriction orifice?



When I get my kit I'll check it out, if I don't have one I'll either make one or buy one from wefilter it I think they were a few bucks.

On another post Srowly contacted fleetguard about bypass systems here is what they told him:



Thank you for contacting Fleetguard.

Steve, Cummins Engine Company neither recommends nor encourages the use of by-pass oil filters on the B engine

because improper use of the by-pass lubrication filter, it MUST meet the following requirements:

A. Oil flow restricted to 1 GPM by using a 2 mm orifice in the by-pass filter supply.

B. A check Valve in the supply line which only allows flow to the by-pass filter supply.



If you use a 1/16 inch restrictor hole this would be . 0625 inches and 2mm is . 078 inches so I think that you would satisfy their part A



Does anyone else have a check valve? What would be the purpose of this? So that junk from the by-pass filter can't drain back down into the block when you turn the engine off??



Still waiting on mine to come in... .

I think they are speaking of a different bypass system... substitute bypass valve for check valve.



As long as you have the restrictor, you should be alright.

Her is a picture of the Amsoil Oriface located in the return side of the mount. This oriface keeps the oil flow at 6 quarts every 5 minutes through the by-pass filter.



The hole is about . 030 in size.
