Oil Bypass filter installation

[Rodd]

Nice job and pics. The one thing i would change beside location is the hoses. I think I would go for braided stainless and use reusable ends. 2 year life on the rubber seems marginal. I'm not thrilled about hose clamps on 60psi lines. I like overkill. Are both filters the same or is it staged [coarse then fine]?

If you look at one of my previous posts, I said that that is what I was going to do next.

Just to clarify unless im missing something on this- It is a remote full flow filter system and not a bypass filter setup, maybe edit the title.

A bypass filter system like used on many heavy duty diesels will tap off the engine oil galley and run a hose to a filter mount that has an orifice of about 1/16 in which flows maybe 1 quart per minute through an extemely fine filter rated at a couple microns to catch all the crap that the regular filters let through with their 20 to 40 micron ratings. After going through the filter the oil is returned to drain back to the engine to a fitting on the oil pan, valve cover or oil cap.

I see your point. That is what the guy called it. It is also what Amsoil calls theirs. I like the idea of having a regular filter in front then a smaller micron filter after. When it is time to replace that is what I'll do.

Nice install!

Thanks!

Thats what I was thinking to.

Still a nice install and will make changing filters next time alot cleaner job. I have a 4x4 and can't stand the mess it makes.

Opps. I didn't see the hose upgrade. I think about a remote filter every time i change oil.With a better filter set-up it should also extend your oil change intervals.

I note that a lot of people mention 'the mess' that changing filters makes. I own 2 4x4s, and I don't get it.

When I loosen the filter, it drains dirty oil down, sometimes hitting the U-joint directly underneath the filter before it goes into the pan I have underneath it. I find that if you rotate the U-Joint by hand, you can often get it to miss that, too. After a couple of minutes, I unscrew the now-drained filter, and wipe off the U-joint with a couple of paper towels. I don't quite understand the big mess? What is so messy about that? It doesn't drizzle down the block, and it doesn't get in my face.

Can someone comment here?

I cannot comment on the unit that Rodd posted, does indeed look like a dual full flow head unit only, however the Amsoil I can. I purchased a used amsoil dual head with bypass and it has no numbers stamped on it but it looks to be the marine BMK18 setup. Now technically it is not a bypass unit there is no separate return direct to the sump however it does take a full flow spin on filter and a bypass spin on filter and effectively allows both filters to filter the oil going to the engine oil gallery so you in effect get both 15-20 and 1-5 micron filtration.
Set up is as follows referring to the attached picture. On the right can be seen the supply and return fittings the top is to the engine oil gallery the bottom is from the engine to the filters, ignore the upper left hand fitting this normally is a plug. The right hand spin on filter port is the larger 1" thread for the bypass element and the left hand is the 3/4" full flow port. The head is drilled length ways from supply and return fittings and is ported equally to both filters there are no restrictions in the mount casting machining itself. You can see that the ports from the supply gallery to the filters is machined equally for both. This means that the bypass filter the first in the line right hand side is able to flow as a full flow filter. Now you no doubt have already spied the spring and plunger in the supply port for the left hand full flow filter element this as far as I can see effectively seals the full flow from the gallery until a specific pressure is reached. They have therefore created a full flow set up on the finer bypass filter as well as the coarser true full flow filter, should the bypass clog then the full flow will carry on with the job.

This is different to how I had imagined they were doing it before actually getting one. I had pictured a head with the true full flow being first in line doing the majority of the filtering and a small drilling (1/16" or so like a regular bypass filter head) from the supply gallery to the bypass spin on filtering a small amount like a regular bypass the only difference being that the return is to the oil gallery rather than the sump. On edit gave this some thought this would not really work though as the somewhat equal pressure on either side of the bypass element would not allow any flow through it and furthermore there is a greater resistance to flow in the bypass element itself. The only effective way to allow a bypass to filter when returning to the oil gallery along with the full flow filter is to allow it to flow like a full flow filter and create a restriction before the true full flow filter to encourage some flow of oil through the Bypass filter element.

Note the above is based on my summations from the actual unit itself and nothing really read from amsoil. They are pretty much non descriptive on how this units actually work.

Now what is also interesting is that their smaller units such as as BMK23 are set up differently with the full flow filter next to the in/out ports and the bypass furthest away and I do not know how those are set up

Anyway this is how the Amsoil unit in my hands appears to work.

Hey Rodd
To establish what exactly your unit either remote dual full flow or full flow and bypass like an amsoil what are the element numbers that is takes?

cheers

Before ordering filter kit, i'd wait for Turbine DOc's filter comparisons between Amsoil and FS-2500 to see if one is clearly superiour. Everyones claims its the best, I want to see Doc's data.

Just because a guy on ebay is selling a regular permacool full flow dual filter unit and putting one full flow and one bypass filter on it doesn't turn it into an amsoil clone. Sorry but the regular dual filter heads have the filters mounted in parallel and the oil will take the path of least resistance which means very little oil will go thru the bypass filter. If you look at an amsoil unit it contains a spring loaded plunger that acts as a restrictor, this creates a pressure delta between the fullflow and the bypass filter, its this increase in pressure that forces a small percentage of the oil to flow thru the bypass filter. If you want a cheap bypass unit for a 6.5, pickup a NAPA 4755 head with a Baldwin B50 filter. Tap into the oil pressure switch for the feed and return into the oil filler cap. Not as good as an amsoil or frantz but it will cost less than 50$. If you want to know everything there is to know about oil and filters spend a few nights on bobistheoilguy.

It is just a dual flow through. Your pic looks exactly like the unit I have however w/ out the spring. Both filters are the same. I will have to check on the p/n's.

I never called it an amsoil clone. If you look at my original post I did it for easy oil changes, cooling, etc. I did look at amsoil however decided not to get it.

Check out the FS2000 videa on how hit is superiour to any others and it will make you a believer. Thats why i've been waiting since july for TD's sample comparisons between Amsoil and FS2000

Duh thanks Dila for the comments on the restriction plunger and spring, I don't know why but this morning I made some schoolboy errors in my thinking this morning. Have edited my post to reflect that

I never said that you called it an amsoil clone. The guy selling them on ebay is calling them a dual bypass filter and they are not, some of his auctions even show an amsoil bypass filter mounted on a full flow head. You did say "remove the stock filter and locate the bypass filters" so I thought that you believed that you had a real full flow/bypass setup. If you have a problem finding the B2-HPG's the Purolator pureone PL30001 is also a very good synthetic media filter and I think is a bargain for $5.

Thanks for the advise. Where are those filters sold?

 

[DILA]

If anyone is looking to add this to their truck, you can save some money by not shopping on ebay.

Permacool 10795 dual filter kit $60
2x Baldwin B2-HPG $20 or 2x PL30001 $10

with tax and shipping should be just under $100.

you can get purolators at any o'reilly autoparts, advance auto parts or pepboys. I even buy them from amazon, they had a rebate a few weeks ago, 2 pack was $9.50 and the rebate was $4.
