How does a by pass filter work? I guess it filters oil that has by passed the filter but how?
By pass filter?

by pass filtration is a special filter that contains dense media that slowly filters the oil. I will remove more contaminants than what a full flow filter can. A by-pass filter is out of main flow of the oil. Typically about 10% of the oil is channelled over to the by-pass filter. Then the super clean oil is introduced back into the system.
By super cleaning the oil you can reduce wear, remove sludge and varnish, as well as remove water, fuel, and glycol from your engine oil. In a transmission you would be keeping the oil free from particulates, moisture, reducing temperautres.
Becuase the oil is slowly going throught the filter it also acts as a cooler. Heat is the number 1 killer of transmissions and increases the oxidation in the oil.
By using by-pass filtration you can increase service interval of the component, increase service life of the equipment. You can install a by-pass filter on just about any piece of equipment that has a pump to push fluid.

So is it a sandwich type adapter that fits between the oil filter and the filter mount? How would it know if the oil had been by passed? I'm not trying to be silly, but just trying to figure it out.
There are several ways actually, not just the sandwich adapter. Basically, all you need is a source, the filter and a return.
In the sandwich adapter oil is tapped from the adapter, routed to an external bypass filter, and then returned to either the adapter or another location.
On my truck I removed an oil gallery plug that was pressurized. Then, I installed a threaded fitting into that hole and routed a hose to the filter. From the filter I ran the return line to the drain plug. Some run it to the oil fill tube.
There are others, such as the Amsoil variety, that have a dual remote filter capability. You install an adapter where your full flow filter goes. This then routes all oil flow to a dual filter setup...one is full flow and the other is bypass. Nifty setup if you have the room. Both return the oil through the adapter at the regular filter location.
There are still other ways to hook them up but the basics are the same....take a small amount of the total flow (~10%), route it to a high efficiency filter for near sub-micron filtration, and then put the clean oil back in. Simple as that.
Hope that clarified it a bit.

Here is one type. That uses a special mount and adapter that contains both the full flow and by-pass:
Here is a single by-pass system by itself. With this you have either plug on the engine block as noted above or you get a T off the Oil sending unit for the incoming oil(dirty) and use either oil pan or valve cover for the return (clean oil)
These are the Amsoil setups. There are problably 50 or so by-pass filter manufacutes. Some use Toilet paper where the oil flows longway through the TP. Others like the Amsoil work like a normal filter where the oil enters through the outside of the filter element then flows inward to the center of the media then back to the engine. This is know as radial flow and usually has a larger filtering surface area.
Most all filters use a celluse(paper type of media) which aid in removing moisture, glycol and fuel as well as contaminant less than 5 microns.

are site supporting memeber of this forum. The other posted links in now way contribute to this site.
you can feel the filter if it's hot oil is running through it. You can also install an oil pressure guage on the the output line and see if you have pressure. That is how you would know.
I think what he was thinking is that a bypass filter filters oil that bypassed the full flow filter due to the pressure differential. I think.

The oil in a bypass filter bypasses the engine's lubrication system. It goes from the oil pump, through the bypass filter, and back to the oil sump. This works very well to completely clean maybe 5-10% of the oil pump's output and soon cleans the complete oil charge. The remaining 90-95% of the oil pump's output goes through the regular full-flow filter and into the engine to lubricate it.

Just to note that 100% of your oil goes through the Full Flow filter before it engines the critical parts of your engine. Note that most by-pass systems are designed to dump the oil back into the sump/drain pan. Though I know other folks that put the return going to the Valve cover and other places.
The Amsoil dual remote has a valve that directs 100% of the oil from the Full Flow past the by-pass to the engine to recieve maximum lubrication until the oil is sufficiently warm to then divert the oil into the by-pass filter element. Hope this clears it up

I was trying to understand the dynamics of using a sandwich adaptor and using the ports usually used for an oil cooler as the bypass circuit so that it would empty back into the flow going into the engine.
I know the flow is greatly reduced, but would there be enough pressure to get the oil back into the stream after the bypass filter in this type of setup?
The sandwich adaptor seems a reliable way of doing bypass that would tend to minimize lenth of hose to run a bypass as well as keeping me from drilling any holes in oil pan or valve cover.
That was good info earlier, I just dont think I saw this particular question answered.
Thanks.

Mykro,
I think the Frantz adapters that you referred to with the urls only have a single connection, to provide a one way feed from the engine to the bypass filter.
I think Dan's question was whether a standard oil cooler sandwich adapter (one outlet port, one inlet port) can be used efficiently with a remote bypass filter.
His concern (and mine) is whether the bypass filter can work effectively when feeding the filtered oil back to the return port of a two port sandwich adapter instead of draining into a no pressure area in the oil pan or a valve cover. The return port of dual port sandwich adapter will see almost the same pressure as the feed line from the engine.
Only the small pressure differential, typically just a few psi, that exists across the input to output side of the full flow filter will be seen by the bypass filter as it tries to return oil to the engine.

OK.. I understand.. I've got 3 Frantz's on my PSD
The return line was easy.. It went to a non pressure port to the block at the oil pan.. I'm not to familiar with the sandwich adaptors..
Mykro,
On your transmission why did you use an inline adapter for your trans filter? Could you not have used the 1/8"NPT plug in the test port and returned to the pan, using a standard Frantz instead of the Trans. Frantz?
Also are you running a Trans Temp guage? And if so what are your temps pulling a load up a hill? Just curious, as I am about to install a Bypass on my 4R100 using the test port and the pan return with a restricted outlet. I know alot of questions, but curiousity got me.

Dan, I don't know if anyone can answer your question with 100% certainty. I think the only TRUE way to be sure would be to install a flow meter in the return line.
First, measure the flow with the return line hooked up to a non-pressurized area (valve cover, oil pan, etc). Then, measure the flow with the return line hooked to the sandwich adapter.
I'm willing to bet that with the adapter there is flow...probably not as much with the return going to a non-pressurized area though.

Mykro,
Does that trans. adapter that you linked to have a restriction in it to get the flow to the filter or does it have a venturi between the two ports? Looks like a venturi would have to be between the inlet and outlet in that adapter to get the flow in and out of the bypass. Help my confused mind please.
