Gerald, Sorry I didn't get back to you sooner. I injured my back and may need surgery I'm going to have to pass on the Frantz for right now. Thanks for all your hard work putting this together. Jim McCarty
 
Last chance to get in on the GP. Since I am waiting for the mail I can still get anyone who is interested. The deadline for those who would send check by mail is Sunday night the 25th. Paypal orders can be taken later or at least till all the checks have arrived. Just PM me if interested. :cool:
 
Just wondering but...

... I remember reading some years ago about "channeling" within those TP type filters. It's where the oil is constantly being pushed through the TP filtering media, trying to take the path of least resistance but, it forms a channel where the oil is able to pass unfiltered. For that reason I chose to go with the Amsoil dual remote bypass filtration system. Yes, the bypass filters do cost more than TP but, they were expressly designed to filter bypassed engine oil, not, well...



:rolleyes:
 
IF you read back thru the posts in this thread (yeah, I know, it's a chore - but it keeps us from having to repeat ourselves... ), you will see a picture of a typical used filter, and read some references to "channeling"... ;) :p



As I myself pointed out, sure, some user out of ignorance in installation, and/or poor choice of TP *can* experience channeling - but to put it bluntly, ya hafta be pretty determinedly dumb and clumsey to do it... ;)
 
Just installed mine tonight. I mounted it next to my BHAF on the inner fenderfell. I wanted more clearance to get to the normal oil filter.

I have a bit over 1k miles on the current oil change, and it is pretty black already. I will be checking it to see how well it cleans up.

Also, if the oil always stays so clean, what is the reasoning behind changing the full flow oil filter so often? I am not really against the idea, I am rather curious of why.
 
Oh, and after you see how tight the TP is in there, I would be very hard pressed to think there could be much for channeling. About the only way I could see that happening is if there wasn't a proper restriction to limit the flow through the filter.
 
I just saw this one and if it is not too late, I would also like to get in on ths. I used one of these years ago on another car and it worked great!!.



Thanks,

Randy
 
Sorry Gary. I DID read the ENTIRE thread last Friday, noted all the pics etc. and did not notice anything on channeling.



My take on channeling was that it wasn't necessarily a large channel that you might even outwardly see. In fact, it could close back up once flow had subsided through the TP filtering media.

You are correct that in this thread, no direct references to channeling were made, other than that implied by my comment that it IS possible for an inept and careless user to buy the wrong TP, then install it poorly - I would sorta think the pics of the used TP roll, and several references to oil analysis would pretty much determine that,:



1. Channeling is NOT a problem. (sure hasn't been in my case!)



2. IF channeling IS a common event, regardless if it's clearly visible in the discarded roll or not, it sure doesn't seem to adversely affect oil cleanliness or analysis results!



I have nothing at stake here - makes no difference to me who does or does not use or like them - I only made my presentation to better acquaint others as to what they are and how they work, as well as my own long satisfactory results with them - glad to see many here feel the same way I do... :D



But again, as also stated previously - if ya don't like or trust them, AVOID them! ;) :D



Can't get much simpler than that! ;)
 
On a 12V engine where did you guys that have them tap into for the supply line. I am think the 1/8 NPT port right above the oil filter. I am thinking that I can put a oil pressure gauge and the Fratz filter right off of that. Please tell me if I am wrong in my thoughts here.



Thanks,

Thank you for your explanation Gary.



As I'm just under half the century mark (in age), I too remember all the Frantz filtered rigs running around in the '60s and '70s. Everyone I talked to about them seemed to be very much pleased with their results.
 
The plugged port on top of the stock oil filter housing is where most of us tap into the pressure point to supply the bypass filter - no reason a separate oil pressure guage couldn't be installed from that point as well. I used the same point on my '91 as well as the current '02.
 
As a matter of fact, the kit even includes the T for hooking up the pressure gauge inline.

I am still debating the Motor Guard for filtering the auto transmission in my Jeep. I just like that design for having it mounted down near the frame rails.
 
I'd be a bit leery of a filter like these for the automatic transmission UNLESS it was also installed in a bypass mode - even without the restriction, the filter is not (in my opinion) capable of the flow rate the transmission must have...
