Oil filter microns with no bypass adapter

[kimosabi]

I can think of one good reason to run a bypass and that is negligent owners. A good oil filter changed at regular intervals will not clog and if you have a mishap creating small shrapnel non bypass will not circulate particles past the filter.

I have a couple rules knowing I run 10-40 oil, I do not fire the engine up freezing cold below a certain temp. I use a heater fan under the hood for an hour or so first, and I never pump the gas until I have cranked for atleast 5 seconds. Very easy to control when the engine starts because there is no choke and it demands two or three times pumping the gas before firing up cold.

My take is if your engine is producing a lot of metal debris larger than 40-50 microns which is a barely visible particle your problem is bigger than just the micron rating of your oil filter. Your oil filter is supposed to remove those and larger particles and trap them in the filter provided your bypass is not opening or plugged. Its important to know and remember that human red blood cells measure between 5 and 10 microns and are barely visible under a powerful microscope. If you use a filter that may remove particles that small you are going to restrict the flow of the engine oil and you can starve engine components that are in great need of that volume of lubrication. Cut open your removed filters and make sure you don't see a lot of visible metal debris or dirt, if you do see that realize that there may be something wrong in your engine where you should concentrate on finding that problem and FIX it!

Trying to re-refine your oil with an oil filter by trying to get particle filtration down to 5-10 microns is a mistake. If your engine operates in an environment where your oil gets fairly dirty then change your oil and filter more often and thus also make sure your oil system bypasses are not opening and redistributing the contaminated oil back thru the engine. Also realize that dirt can enter the engine easily through the air intake system and it will migrate quickly into the oil and contaminate it.Use good air filters and make sure its not entering from breathers also especially with crankcase vacuum systems.

We run a 6 micron filter.

How do you configure or manage to get the oils you run flowing at enough volume with that small a filter micron rating . I am all ears.

I've seen about a 5-7psi pressure drop through the filter @ well over 10gpm, but who cares?
Micron rating needed, goes hand in hand with the clearances used in the engine.

Warp, what oil and how big is the filter?

Let's say 10w-30ish for the sake of discussion, and an oem type filter size. Not the old standard sbc large size.

Run a full flow filter w/o a bypass then hook a small micron bypass filter like an Amsoil or even the old style Franz filter... Problem solved.

Then you've just increased the the flow restriction AND vehicle weight! Lol

I'd prefer running engine without oil filter than with filter without bypass. It only need a little bit water in coldish oil to clog oil filter totally and burn bearings. Which is more likely to happen, debris or water in oil?

Most engine bearings are made from soft metals, which do absorb unwanted particles in bearing metal. Without something broke in engine bearings usually don't catch anything even when used without filter at all.

Weight yes...but you just tap into an oil gallery and filter just a bit if the oil...no restriction in flow.

Respectfully, you're making this waaaaay harder than it needs to be.

I just purchased a case of Wix 51061. I don't want to think about this anymore.

Pretty simple install actually... you'd just have a partial filter just like millions of class 8 trucks ran for years. The old LuberFiner filters were the standard before full flow filters were common. One pressure line and one return...

I think it's simpler to just run a large capacity single filter.
