Guys, member CPFF - John Strenkowski - sells mount kits and billet adapter kits for 3rd gen trucks. The adapter that comes with the Amsoil kit is NOT billet, and is prone to leaks etc. Johns kit comes with pictures of every step of the install, and the billet adapter is sweet. I have both the amsoil bmk-15 and john's kit sitting here in front of me. I'm just waiting for the ticker to hit 15k miles before I go synthetic!:D



The mount kit is completely bolt on, no drilling. The bmk plus johns kit came out around $300.



Finally! Good info! Thanks!
 
For the benefit of Joe and others, I will try and clarify the way the AMSOIL by-pass system works.



In the case of the BMK-15 (duel-remote). This mount allows both the “full-Flow” and By-pass elements to be located on the same mount.



All of the oil is circulated at a high flow rate and “Normal” oil pressure through the duel-remote mount, going through the “Full-Flow” filter element and back to the engine. Along the way, some of the oil is circulated through the by-pass element, (10-15 percent of flow) as there is a channel built inside the mount. Now the by-pass element itself has a very restrictive filter media, so by design, it will not flow oil through it very easy. This allows the oil to flow through the by-pass element very slowly, about 6 quarts every five minutes with a 40-psi force pushing it.

Eventually, all the oil will run through the by-pass element, and the oil will stay analytically clean.



Now for the BMK-11. (Single remote) This mount only allows for one filter element, and that of course is the by-pass element. The “Full-Flow” element remains in the stock OEM position. Oil is fed to this mount from any oil pressure source. Typically, on the Dodge this is the 1/8th NPT port on the top of the OEM filter mount. This oil line feed is of high pressure, and is directed to the "inlet" port of the mount.



Oil under pressure is then fed through the same dense restrictive filter media within the by-pass element as is used in the duel-remote unit. As the oil goes through the by-pass element, it will exit through a very restrictive orifice and return back to the engine under very little pressure and flow due to this . 032 orifice. This orifice does two things; it keeps the oil pressure up, as the orifice is on the outlet side of the by-pass filter, and will only allow about 6 quarts of oil every 5 minutes to go through it, with a 40 PSI force pushing it as was mentioned above.



So to address Joes concern about the loss of pressure, There is no loss of oil pressure!



Oil is returned back to the oil pan anywhere one can find a good return, such as the valve cover, oil fill cap, or oil pan. I use the oil “Fill Cap”, by modifying the cap.



The biggest advantage of the duel-remote is the fact that both filter elements are mounted in the same place.

The bottom line is that both systems will filter the oil the same.





Hope this information is helpful.

My Frantz bypass uses a 1/8 restriction orifice - internal filter media is different than the Amsoil - flow probably a bit higher, judging by output stream - NO discernable oil PSI reduction as near as I can tell by the instrument panel guage, I use the same supply line Wayne mentions above, at the top of the stock filter housing - these engines have a VERY high volume oil flow - a reasonable bypass filter will not compromise proper oil flow.
 
Thinking of the auxiliary oil filtering system, wouldn't it be better to have a total secondary filtering system containing it's own pump, independant of the engine and taking from and returning to the sump? Tampering with the original design can, and often cause problems, after all, how Cheap can one get? I never cared for "Slave Systems" even if designed by the original manufacturer, not forgetting, design engineers have a Bean Counter looking over their shoulders. Most products are built down to a price, and not up to an ideal. Scrum Down
 
Joe D, since the Cummins oil pump is capable of flowing 17 gallons per minute I hardly think it's going to miss a piddly 6 gallons per hour being bled off for the bypass filter :p



LOL couldn't resist :)

Thank you Amsoilman. I was just gettin' ready to chime in when I saw you had responded. Your astute prose is always appreciated! I'm looking for a place to install my dual-remote mount. Anybody done this already?

I was just looking where to install mine last night. I think I will mount to the frame on the passenger side (would be right under where the front passengers feet would be located. ) This location would be fairly easy to change filters on and would not need any 45 or 90 degree fittings. The lines supplied with the dual remote will also be long enough. The last Dodge I had one on fit right on the firewall, but it was a gasser. One tip before you install, put both fittings with oil lines on the adapter that goes where your original oil filter was, they are hard to get on once the adapter is in place. I have installed about a dozen of thes systems on Dodge diesels, but this will be the first 3rd gen. Where ever you put it, be sure the filters don't stick down where they could possibly be hit by something. Good luck!!

I notice no drop in pressure on my factory gauge. I also have a low pressure alarm on the pressure side of the bypass restricting orifice so if a hose or fitting ever lets loose I will know it right away. The flow of the bypass is not the issue that concerned me it was the quality of the fittings, hoses, and filter head. I didn't like the old cast filter heads and clamped hoses. The new Amsoil bypass units are much better.



Too bad Joe D. isn't doing the statistical analysis for the marketing people and accountants at DC. We could have a 500,000 mile warranty!
 
Thanks! I have run one of these before on a 2000 Honda Odyssey. Mounting it was a PITA (behind the engine, topside under the windshield bulkhead AAARRRRRRRRRRGH!!! Tight fit on an Odyssey I'll tell ya! Once mounted it worked like a charm though and with the oil analysis I knew there was a problem with the emissions system (turned out to be the PCV valve) before Honda issued the recall! It DOESN'T affect oil pressure and ADDS oil capacity & cooling for anyone who may be concerned. What's nice about the new Amsoil mount is its flexibility-----I'm using the very same mount I took off my wife's Honda with a new oil filter adapter to fit the Cummins. I will check into the billet adapter too.
 
Thanks to all for the good responses. On another discussion forum that I use, there is a way to give votes for good replies and the person that gets the most "stars" every week gets announced on the home page. Don't know if he wins anything though. I think it is a good idea - wish we had one here.
