Anatomy of a Frantz toilet paper bypass oil filter

[amsoilman]

For those of you looking for a good option to return oil to the engine on the 24V engines, here are some pictures.



I aquire a "fill" cap from Checker Auto (stant makes it) and then modify by simply drilling and installing an Amsoil BP-89 (Swivel) fitting with a 1/4/ to 3/8 Bushing. I used to modify the OEM cap, but found the Stant to be much easier.

Another Picture. This view also shows the 1/4 to 3/8 Bushing used to extend the BP-89 through the cap.

And another picture. This picture shows the 1/4 to 3/8 bushing that will extend the BP-89 through the cap.

The Amsoil swivel, unfortunately, is about 3/8 inch too short for our 2nd generation oil fill caps, which is why it took me a while to finally install mine after modifying it. I didn't want to tear the 2-piece cap apart - the original plain elbow was working perfectly, so no real rush to adapt the Amsoil unit.



BUT, since I had bought it, figured I might as well get it installed. I got a brass fitting outta my parts box that had the same thread as the Amsoil unit, cut the threaded part off one end, and drilled out the inside, leaving me with a threaded sleeve, so it would slip over a 1/4 inch piece of copper tubing about 3 inches long. I next drilled into the Amsoil lower section about 1/4 inch so it too would allow slipping the end of that tube into the relief I had drilled, slipped the tube into it, with the short threaded section I had cut off the fitting earlier, and then soldered the whole shebang together. I now had a single solid unit with threads long enough to reach all the way thru the stock cap, with a couple of inches of tubing extending down into the valve cover area. I prefer to extend the oil return down into the rocker cavity to eliminate oil blow-back that might occur if you try to dump the oil back in directly under the bottom of the oil fill cap.



Works great!

rbattelle,



That filter is the Exact same one I use on my shop air compressor. Bought it with 3 extra tp cart. for like 69. 00



Motor guard brand.

Chipstien, I'll take one (1).

Ralph Woods at: www.bypassfilter.com sells both the Gulf Coast (paper towel) and a TP type called Motor Guard Oil Filter (lower cost than Franz). He has been doing this for over 20 years. I have the Gulfcoast that I have used on two Ford PSD and I am waiting for my HO600 due soon to install it there. Ralph took the Gulfcoast off for me and told me that he had found a better filter for the Gulfcoast than paper towel. He came up with this for his job at work where they needed less than 0. 1 micron. He has a 1-800 number on his WEB. Cozy, The Old Fighter/U-2 pilot...

I used to change TP in dads 50s trucks with Frantz filters. I couldn't agree more - they do a great job! Could hardly see the oil on the dipstick. When I was in Co. , I found a guy in Berthoud with an attic full of the old Frantz TP. About that time, Oilguard had a sale and I got their filter and a 20 yr. supply of elements for <200$. Otherwise, I would have used Frantz. But, I was a little worried about modern TP - being septic safe(breaks down easily) etc. Who saved Frantz from extinction after George Walker died? George gave me a Fort James TP part# that fits the Frantz properly(1. 5" ID) - I think it was 17500. Someone might want to check that out, for a group purchase, also. Doesn't Frantz still make the TP to fit their filter? Craig

I doubt Frantz "makes" the TP for their filter - probably just found a good commercial source they trust - as to who "saved" Frantz after the original developer, I know the "Sky" outfit marketed them back in the 60's, and that name is embossed into the filter canister of mine along with Frantz, as you can see in the photos about the frantz in my "readers rigs" section of this board...

I had to sleeve my 30 year old Motor Guards. They were designed for the old 1 1/2" tp. I am setting the new Motor Guards up to seal inside the new 1 5/8" core tp. I use Scott Kimberly Clark in mine. I only need to unroll 10 rounds of paper. The Scott 1000 sheet is just as good but it must be about 50 rounds too large. I stopped worrying about paper fibers many years ago. The Motor Guard has no screens. They did away with the screen in 1966. If I have someone that is worried about paper fibers I install a secondary cintered bronze filter at the outlet. You are a little over kill on the extras. I cant bad mouth the Frantz oil cleaner. I have one that is over 40 years old and has saved me thousands of dollars. The normal size for the orifice is 1/16", 1/8" is much too large.

As far as warranty the only thing I have is from Cummins, Cat and Detroit. They arent responsible for any thing you put on your engine that isnt theirs. I think the filters are for people that worry more about dirty oil than about warranties. I read one letter from Cummins that said if not following our recommendations causes engine damage the warranty doesnot cover it. That sounds fair to me.

Here is an article I obtained back in 1998 regarding By-Pass oil filters. It was found in a "Fleet Equipment" Magazine.



Title: Don't Bypass Bypass Filters

Author: Gelinas, Tom

Journal: Fleet Equipment Vol: 14 Iss: 7

Date: Jul 1988 pp. 39-41 Abstract:



(QUOTE) According to some estimates, 60% of the potential causes of engine wear and failure can be eliminated by a well-designed and properly applied filtration system. Cummins Engine Co. recommends that both a bypass filter and a full-flow filter be used.

A bypass filter shunts 10% of the total oil pump output through a filter and then back to the sump, bypassing the engine. Because this filter has high-pressure differential and low flow rate, it can filter out fine particles in the 5-micron range. In contrast, a full- flow filter has a low-pressure differential and filters out only large particles in the 40 micron to 60 micron range. However, the full-flow filter is located so that all of the oil must flow through it before reaching the bearings.

The combination of these 2 filter types gives double protection against wear. Studies at the Cummins Technical Center indicate that wear can be reduced up to 91% by using a bypass filter in combination with a full-flow filter! (end QUOTE)



I am my own warranty station, but a By-pass oil system WILL NOT VOID A WARRANTY! Chrysler tried that back in 1983 when Amsoil came out with their By-pass system. Chrysler was "shot down" in court!

John Birdsell (TDR advertiser--GCF of Oklahoma) offered a group rate on the paper towel GULF COAST filter that I have.



Puchase three and get them for $350. They're much bigger and heavier than these TP filters. BUT the TP filters better.



But let's don't muck up this thread. We can start a new one if'n anybody likes the big filter better.

The tradeoff between paper towels and TP was explained to me like this: paper towels don't filter as small as TP, but are able to filter a significantly larger volume of fluid. TP filters smaller particles, but can't handle nearly the volume of paper towels.

GREAT info on bypass filtration, and from a reputable independent source - thanks Wayne.

I was wondering about that. I can't say as to whether or not 1/8 is too large being how restrictive the TP filters are but like Ralph said the Frantz uses a 1/16 " oriface. Gary, are you sure yours is 1/8"... ... . maybe they have changed down through the years.

 

[Gary - K7GLD]

Look at the picture at the beginning of this thread, and make an "educated guess" as the the size of the orifice shown...



The restricted base pictured at the beginning is my old original, bought back in the 60's - and what you see pictured is the standard restriction - but I installed a new base on my '02.



In my case, the base I used was not already restricted - some Frantz filters are used in other applications where a restriction is not used - I made my own, and used a 1/8 inch bit to drill the restriction - judging by the appearance of my oil and analysis to date, it seems to work...

 

[Chipstien]

I will take some pictures of the Frantz filter I just recieved on Friday and post them on this thread. On thing for sure, on the current units the TP fits snug on the core tube so by the time the TP expands I cannot see how it would "bypass" the cartridge. Granted that is with the roll that came with the filter. I will have to measure the core diameter and see if it is 1 1/2 or 1 5/8.

 

[Gary - K7GLD]

Personally, I prefer a more positive seal at the inner core than is available merely by manipulating to post diameter itself - the O-rings I use do that nicely with the current post diameter, and it might be difficult if the post was larger, but the core seal not sufficient.



Realize, I have no proof or way to check what actually is taking place in regards to oil flow (if any) at that point - I merely use the O-rings as a precaution - the good oil analysis results I got were obtained before I even started using the O-rings...
