Anatomy of a Frantz toilet paper bypass oil filter

[Coalsmoke]

Here's an interesting thought, I wonder at what point a roll will be too dense such that it will overly / unnecessarily impede flow. It might filter a little bit better, but if its significantly reduces the flow then maybe it wouldn't be to the advantage of the overall bypass filtering efficiency.

I use the most dense rolls I have yet to find - the ones sold by Frantz - and reliable flow is NO issue. And of course, the whole POINT of proper bypass filtration IS low flow, to allow best entrapment of contaminants in the lube...

 

[Coalsmoke]

Of course low flow when speaking relative to full flow, but there has to be a point where too low of flow is a detractor. No flow would be an excellent filter, but it won't see a high enough % of the total system volume to be effective. Just a hypothetical thought. I wonder if Frantz or Amsoil has done testing to this regard?

About the only way to excessively restrict flow thru the bypass, is to provide too small a mechanical orifice to the element - the common size for that restriction runs from 1/16-1/8 inch.

Okay, I changed my tp roll last night a couple hundred miles early and used one of the frantz rolls. I did not do the shop towel trick because I went to test fit the frantz roll and noticed how perfect it fit in the cannister (tight). Here is something I did notice though. After firing up the truck I noticed how much longer it took to get flow to my valve cover return. Also with the scotts 1000 it would almost burp with air until the flow came out steady, it did not do this with the frantz roll. Not so scientific or anything but it looks like the frantz does impede flow with its denser roll which should result in cleaner oil. I would like to have an earlier motor and see the results but its hard to see anything since the oil is black all the time.

It was also nice to just grab the roll and not have to guess how many wraps to unwind. Even though the price is much higher than the scotts I think I will stick with the frantz rolls from now on. I have enough for the next two years or so.

Thanks for taking the time to post that MX.

Installed my Frantz tonight

I would like to thank Gary and all the members who have contributed to this thread, I have read it begin to end. I purchased 2 complete units for my truck from Debra at we filter it. She we very helpful, even threw in 2 packages of tp filter, extra gaskets, and marine upgrade for no charge. I did not realize the kits came with teh Amsoil swivel fitting, I ordered these seperate, so now I have 2 extra.

The install on my 05 was very simple, I made a braket out of 3/16 aluminum and ground it to fit and capture the 2 bolts on the exhaust manifold shield. I then bought a Stant fill cap and drilled the hole for the swivel fitting. I also used rubber washers on the mounting bracket to help with any vibration. All in all I like it! I will see how the oil looks after a couple thousand miles. The oil already has almost 2000 on it now, so it is really black. Here are a couple pics for you 3rd gen owners. Thought I should contribute to this thread, to help other out as it did me. I will get the other unit on the 12V later this week and post some pics.

Thanks

Nice install, I like the custom bracket. I mounted mine over by the battery. I made a custom bracket that attaches to the battery hold down bolt. One thing you might want to watch for a while is how hot that filter gets being that close to the exhaust manifold. You don't want to cook your oil. Other than that, good job.

I doing the same thing with the GCF... buying their elements, its easier.

I just pulled off my old style Frantz setup yesterday.
I had a few issues that I wanted to FIX before I put it back on, and I didn't feel like messing with them on the truck.

First thing, the swivel adapter I got from Amsoil started leaking, and pretty bad the last trip or two out.
Turns out that oring in the swivel was not happy. The odd part here, it was gauling the brass on the outside of the oring where it rubbed when it swiveled. Maybe it got something in there that acted as an abrasive?

Second, and I know this has been covered, but the TP never really sealed to the tube very well. I always seemed to be in a rush when I changed it, so I never got around to fixing this issue.

What is the best route for sealing the inner TP to the tube? Orings, other fittings, etc???

And are there any other swivel fittings for the oil cap?

If you go back to the beginning posts in this thread, you'll see the neoprene O-rings I use for sealing mine...



And you are the first I've seen with swivel-fitting issues - maybe you just got a defective one?

Yeah, I knew you used those o-rings to seal yours. Which will most likely be how I end up sealing mine.

I was just curious if there were any other methods that seemed to be working well?



No idea on the swivel. I haven't heard any other complaints on it. Maybe I just got a bad one to start with. Can't really tell if that is the case now.



I notice you don't have a swivel on your first post pictures. That work ok for you?

No, the original return setup was awkward, and tended to leak - the Amsoil swivel has been faultless.

My swivel fitting also leaks a little, or should I say sweats oil. All I do is wipe it down once or week and that has been the extent of it.

 

[steved]

Mine started leaking about 3 weeks after I installed it. I replaced the oring, and within 300 miles it was leaking like a sieve. I ended up replacing the oring (which had hardened) yet again, and it has been fine since. It does not weep, seep, or otherwise drip.



I have not had it apart to see if it has any signs of wear or galling...

That was all mine would do for quite a while. But then it really started leaking recently.



My o-ring was pretty hard. And you could see the wear on the o-ring itself from the gauling of the metal.

I will try and get a picture of it today.



Maybe I had to much slack in the line up to the fitting, and it was constantly moving.

And this constant movement was enough that over the years it wore into the metal?

 

[Froadin]

Ok, here is a quick picture I took of the gauling on mine.

 

[steved]

Have you seen if it will seal with a new oring? (I missed if you already posted this).



That shouldn't affect the sealing of the oring... but it s probably from the hose vibrating... does the hose "hang" on the fitting?

 

[Froadin]

I haven't done a new o-ring yet.
I just ordered a new one.
I will put a new o-ring in this one and keep it as a backup.

That groove goes all the way around the inside.

And yes, the hose was hanging on it. I didn't think it was too bad, but I think between that, and the extra movement, it wore the groove in it.
