Oil filtration
« on: March 29, 2022, 02:52:21 AM »
Folks- I thought I'd post a picture of a combination of what Butch recommended, as well as my adaptation.  I've used a toilet paper filter in my paint booth for years.  Works great.  No "fuzz" through the lines.

These toilet paper filters have been used for years on oiling systems.  Got this one, a "Frantz", new in the box.  As you'll notice, it's plumbed up quite nicely.  And, Butch recommended I feed lubrication to the second pump cam on this twin.  That jobs' now done.

For what ever reason the image will not download here.
Those very old fashioned toilet paper filters were used briefly on trucks here in Australia back in the 1970's but they soon lost favour against buying proper filters due to the life shortening effects they had on the truck engines because quite simply they do not filter fine enough to remove the nasties from the oil, only bulky stuff.

Cobbadog- I can assure you, that through both my personal experience in paint spraying, as well the (admittedly advertised) testimonies written on the Frantz website, the toilet paper filter is superior to ANY other attempt I've tried. 

When spraying high-gloss black paint on a vehicle, even the most minute particle can be seen.  The smallest fiber will show up, as it's got the surface tension to break the continuum of the paint film.  At no time have any of the fibers of the toilet paper roll found their way onto any paint I've sprayed.  Nor have other foreign objects found their way into my paint.  Thus, I must find that "bulky stuff" and fine stuff IS successfully filtered through toilet paper.

Likewise, please bear in mind that once a standard oil filter "clogs" and the spring-check valve is opened due to excessive pressure to the oil filter, ALL oil goes into the by-pass circuit, and up into your engine.  Unfiltered oil.  This Frantz filter uses no bypass valve.  All oil that enters its system is filtered. 

Obviously, any filtering that does occur with the Frantz filter is done so through the paper element chosen by the end user. Thus, IF one were to use a poor choice, or a mis-fitting paper element, the filtering characteristics would be inferior to a superior choice. 

In general, the Frantz concept is used in concert with a primary oil filter.  BUT, one CAN use an adapter to cause the Frantz filter to be used as a primary filter element. 

One more point:  ANY filtering of oil in a Listeroid engine is superior to NO filtering of oil in a Listeroid engine.

This is awesome, I think I'm going to do the same thing on my twin.

Have you had any trouble finding rolls that fit? I was doing some reading online and it looks like the rolls today often are not the same size as when these filters were originally made.

The kit comes with paperwork that recommends certain inner roll sizes, and maximum diameter.

Cool, has anyone tried using a standard 10" water filter hosing and those paper/cloth filters for oil? I've seen people use them in diy bio-diesel setups to filter the wvo, even when it is being heated.

Gday powdermonkey,
I have no doubt it is adequate for spray painting but in that situation I will still use my water filters and my head mask designed for that use.
As for filtering oil in engines again I agree that any kind of filtration is far better than none. One of the reasons they stopped using this type here in Oz is that it was not adequate enough to filter all the baddies out of the engine oil in the trucks and at the cost of a rebuild they soon got a bad reputation as not filtering enough. Then as you mentioned there is no provision for a bypass for when the toilet roll is clogged up and in turn starves the engine for oil which is not good.
At the end of the day if I wanted to filter the engine oil on any of my engines I would fit a proper cartridge filter which oddly engine is what I did to my CD8hp which was a nice little set up off some VW model car unknown model. I am not being critical of your choice as to what to use on your engines just pointing out the risks

Here is a picture of his installation.  The oil line to the #2 side pump cam is a modification I do on all twins and he added the filter in line.

Neat looking system. Is the blue knob an adjuster for flow?
I was going to fit a 1/8" line up to the rockers on my CD but have not bothered to do it as yet.

The blue knob is simply for tightening the ring clamp around the filter body.

Hi Folks-

16hp twin is up and running.  The oil by-pass and toilet paper oil filter appear to be doing the job.  No leaks whatsoever.  I retorqued the head after a 20-minute run time.  I'll check the oil quality on the next run.

Well done. Can you post a video or some pics at least please? Always like hearing that another engine has been saved.
