flathead oil filter

[mrtexas]

Is this worthwhile to add to a 41 engine? Not full flow? How is it plumbed, from where to where?

Takes pressure from the same place as all filters right beside the oilpressure sender.
Return is done with a banjo fitting and a hollow bolt early kits had return plumbed into the front by the distributor later up by the fuelpump stand.
A return into the oilpan is prefered if you have an inlet for it.

If I had an engine that didn't have a filter, I would put that on in a heartbeat. I have long held that the bypass filter systems originally supplied with these cars are probably the best way to go, superior to a full flow system. A bypass system does filter all of the oil in the engine, it just takes a little longer. Because of the way they work, these systems can filter out smaller particles than a full flow system does. Given the meticulous maintenance most of our vehicles receive, more contaminants are removed from the oil during the working cycle. The fact that it may take several minutes for all of the oil in the engine to pass through the filter, rather than a few seconds that it takes with a full flow system pales in comparison to the better filtration taking place. Sure, a full flow system is probably better for daily drivers that are neglected and driven under all kinds of adverse conditions, by people who are not concerned with maintenance, but for the vast majority of our cars that are pampered by their owners, a bypass system is probably a better choice.

I return my oil bypass filter to the top of the timing cover. Drilled and tapped 1/8th inch pipe thread just below gasket surface of the timing cover. Returned oil quiets timing gear.

There are those that extoll the virtue of the a modified engine with the full flow system however I strongly suppo0rt the original system. It was engineered for the flathead engine and works.

Guess I'm lucky. My '47 with original 59AB engine now has 35,000 miles on its rebuild, never had an oil filter system, still puts out good oil pressure and doesn't burn oil. I do change the 10w-30 oil each 1,000 miles and it drains-out relatively clean. I modified the air filter to use a K&N paper-type filter, add MMO to my gas, and idle the engine as little as possible. I'll stay with this game.

I won't disagree that the by pass oil filter works, I read somewhere that all the oil goes through the filter every 20 minutes or 20 miles. I forget which. My concern is the type of filter used? is it an oil filter or a roll of toilet paper as some have used. Also, the size of thee restrictior hole. I agree with the fact that some people hake good care of their cars and engines, but some don't. I've taken apart dozens of these filters and found most to be clogged/

[flatheadmurre]

Flatheads used normal style filters from start.
The toiletroll filters was the Frantz filters if i remember right.

Later in life, my old man was a rep for a number of odd-ball companies, among them Franz. The gave him a sample and he had me install it on his '55 Olds. They supplied a sticker that was like the door jam oil change stickers they had in those days, only it was made of blotter paper. You were supposed to touch the end of your dipstick to it every 200 miles for the first thousand miles. Some of the oil would be absorbed into the sticker. The change in the amount of dirt in the oil was amazing; the last "spot" was almost perfectly clean. When it comes down to it, the combination of a full flow filter and a bypass system is the best deal. That's what's used on big rigs that log over a million miles.

"Ol' Ron" - How many of those clogged filters came out of "hobbyist" cars? I'll bet not many. I would guess that most of them came from engines or vehicles that had reached the end of their useful lives, with the attendant neglect and wear. Every time I change a filter on one of my cars, I look it over carefully and feel like I'm putting a ten dollar bill in the garbage.

This should give an idea where the return line goes into one of the timing cover bolts. ( from the instructions)

I have two flathead vehicles, an 8BA and a 59AB, both of which I have overhauled. I change the oil every year or every thousand miles if it comes first. I have removed the original filters from both engines. The oil is fairly clean when I drain it. I always felt the bi-pass filters were not that effective. Any comments? Thanks!

The bypass filter works great, I just don't like the look on a modified engine.

Sounds like we both get good results without filters. What's important is that all of us care for our dream cars and help them live a little longer.

So mount a beehive on the firewall.

The beehive is cool, but I prefer the 95% setup with the filter mounted out of sight.

What has been not mentioned here is the micron size of the filter element.

What is the micron. size of a by pass filter ?

I doubt it is anywhere near a full flow filter.

It is certainly better than no filter..

But to say it is better than a full flow is a fanciful dream.

[Frank Miller]

bypass can have a finer element because the engine is not dependent on that oil. It's like a separate system for filtration. That is why some prefer bypass filters. As some of you saw form my oil reports running a bypass did fairly well. Ron said something about the filters being plugged, which would not cause oil starvation in a bypass system.

Care to elaborate? Inquiring minds want to know.

I have a full flow filter set up that returns the oil back into the side of the oil pan after it goes through a screw on filter ((common type Hastings LF115) which is located on the frame rail behind the drivers side running board. Works great, and I purchase the filters six at a time on line.
It about "you", if you don't keep an eye on the oil and change it when it needs changing it doesn't matter what kind of system you have. The cost of an oil change is cheap insurance Seeing, and smelling clean oil on the dip stick is a good thing.

Perhaps a better visualization of the "micron" filtration capabilities of both type filters.
