Amsoil Dual Bypass

[PZicha]

I know a few of you are running the BMK11 single bypass systems , have any of you grafted the BMK12 DUAL system to your truck . I just installed one , I know its overkill but what the hell . If you want a better look go to the link below and press (prev or next) #ad

Sweet install! I like the clamps you used. Looks like you got it down on quality work.

I like under the hood of that red Pontiac!! Are those the standard Amsoil mounting hardware that came in the kit?

Would like to know how clean your oil looks after a few thousand miles.



Can you, or would you want to add an oil cooler inline?



Ive been pondering adding a big oil cooler to the system, for towing through the desert.

 

[PZicha]

Thanks for the kind words guys . The Transam is not an amsoil set up (reg filters) If you are refering to the truck those mounts had to be fabricated , Very easy to do 3/16 steel and some paint . Amsoil sends mounts but I couldn't use them . Yes you can definaitly add an oil cooler / thats next on the shopping list . The thing I like the best is the fact that I have almost 16 quarts in the sump now . I had 2000 miles on the oil when I installed the system and the oil was starting to change color (black) after I went on a 200 mile road trip I checked it again , it was hard to see it on the dipstick... I am very happy with the install :-laf :-laf

Yea, that sure is a clean looking install.



If your oil went back to clear, after getting dark w/o the filters, Id say thats better than my frantz toilet paper filters. They only keep the oil looking clean for awhile. By 2000 miles, the oil looks pretty dark. Its better than w/o, but would never make it clear again. Pretty impressive.



Yea, been wanting to add a cooler, just have been pondering the best way to do it. Your setup makes it easy.



We pull through death valley alot, and in summer, its really hard on a motor pulling the grades in 115-120 degree heat. The cooler should help alot.

Nice setup. I am running the BMK12 with the adapter to move the stock filter up onto the Amsoil mount. Is that 2 bypass filters on your Amsoil mount? If so how did you get the the bypass filter on the full flow filter thread? I like the idea if thats what you did and will do it if possible.

Peter,

Perhaps you do have "Overkill", but the install you done was one of the best I have seen! I have done installs myself using the BMK-11 "Single" remote, but I always return the oil to the "Fill" Cap, as it makes a very nice way to get oil samples for oil analysis. You did a great job with the BMK-12 "Dual-Gard" filter kit.

Just to not confuse anyone, the BMK-15 is the "Duel-Remote" for the Dodge/Cummins, and does carry the "full-flow" filter as well as the "By-pass" filter elements. The BMK-11 is a "Single-Universal" mount (only mounts the "By-pass" elements), and leaves the "Full-flow" filter in the stock location similar to the BMK-12 you used.

first of all. . that is a sweet setup. Good Job!!!



Second... if you don't mind me asking, has that setup affected your oil pressure at all?



I have the BMK-15 installed on my truck and I am very seriously contimplating removing it. I feel personally that my oil pressure is to low.



I NEVER see about 40 and if I am at a stop light idling for a short while, I see about 25-30. Personally, I am afraid of damaging my engine with my pressure being this low. What do you guys think?

To clear up things the BMK12 ONLY uses 2 bypass filters (my setup)... ... the BMK15 uses one bypass and one full flow - Deezul 1 that would be your setup. The BMK12 is mainly used on semi's thats why the one I did is considered overkill , as far as oil pressure the difference is almost non existant it is ever so slightly lower, but this may vary from motor to motor or maybe setup , I just know on mine I am hard pressed to tell the difference either way... oh before I forget the oil is amsoils 15/40 diesel marine

 

[Ted Constantine]

Peter I think you have won the cleanest oil on the board award or at least the most filters. What is you schedule for filter changes, sampling, etc?



Ted



Very clean install

 

[PZicha]

Full flow every 5000 miles / bypass every 25000 miles , I will sample it at 10000 , 15000 , 20000 miles and change the works at 25000 miles or once a year which ever comes first

 

[amsoilman]

K_Arts,

I wouldn't worry about your oil pressure if you have at least 30-40 PSI at operating RPM. Most all of the School Buses we have in our School District run around 25-40 PSI at operatng RPM's. These buses have the 5. 9 CTD in them.



My . 02 cents worth

I also have the BMK-15 dual remote, and I also am considering changing to a single bypass design. I don't believe our oil pressure is really too low, but, I know in the long run I'll be more comfortable if I get it back up to "stock" pressures.

I must say though, I did my first "full flow" filter change today, and the "dual remote" location made it far easier than any previous filter changes.

 

[Don M]

I too had a slightly lower oil pressure than the stock filter set-up when I had the daul remote bypass filter.

Im not gonna say the low oil pressure is a problem, but I thought I might add that our turbos need good oil pressure for the bearings.

Recent failure analysis of many turbos from Holset are showing an oil starvation problem in the bearing area.

Improved oiling is one of the mods that Piers is doing to his turbos to help address this.

I hate the stock full flow changing. Big pain in the rear and I do it about every 2500 miles now. Recently I have talked to a bunch of guys using the single by-pass set-up and they like it.

If I ever de-tune this hot rod I might try that route.

Oh, I wanted to add that I have the upfitted 24 valve oil pump in my 12 valve engine too.

Are the dual bypass filters in series, or parallel w/ each other?



If they're in series, then they would create less of a pressure drop from the system compared to just a single. This is due to more restriction using 2 compared to 1.



Maybe theyre in parallel, not sure, but that was one of the reasons I ran 2 frantz filters in series, was for less pressure loss & to slow the flow down through them so the pressure doesnt blast out the paper, & possibly catch more of the small particles (wishful thinking).



Seemed to make sense.

 

[amsoilman]

Shortshift,

The Amsoil Duel-remote (BMK-15) by-pass systm is a series/parallel system. The "Full-flow" element is in series with the oiling system of the engine, and the "By-pass" element is in parallel with the "Full-flow" element. This routing of the oil takes place in the mount. The Single By-pass (BMK-11)mount is connected in parallel with the "Full-flow" filter. The double (BMK-12) is a "Dual-Gaurd" mount that has the capability to screw on "two" By-pass elements, and is connected in parallel with the "Full-flow". This last system (BMK-12) is what PZicha has installed on his truck.



Hope this helps.

Wayne,



i don't think that you have answered Shortshift's question. With the BMK-12 are the by-pass filters in series with each other? That is, does a given "unit" of by-passed oil flow through both filters before returning to the system or is some of the oil going through one filter and other oil through the second? Or at least this is the question I hope shortshift was asking.



Thanks

Ted

 

[amsoilman]

Ted,

As I recall when I went through training, the (BMK-12) Dual-Gard By-pass system allows oil to flow though both elements equally before being returned back to the oil sump. It was primarily designed for engines with oil capacities larger than 20 Qts.



Thanks,



Wayne

I thought that by-pass systems were just that. I thought they took a small amount of oil that was by-passed to the element for filtering. Is the BMK-12 a by-pass? What am I missing?

With two large filters that are by-pass type how could you push that oil through there fast enough? Im confused here.
