Updated oil filter system

[outsider347]

Gents,
With my 59 an apart for rebuild. I'm interested in a better oil filtration system.
Seems to be info out there, but I'd like a bit more specific info prior to drilling my block

Wondering which mod you guys liked?
And where to find specific info

Thanks Gents

For the use most of these vehicles experience these days (operation on paved roads, impeccable maintenance, and low yearly mileage), I prefer the stock bypass filter system with it's ability to remove smaller contaminant particles.

tubman makes a very good point. Unless you're building a race horse engine, OEM oil system is all you need.

[ford38v8]

There is no better system than the one you have, particularly with using detergent oil as available today. The Ford bypass oil filtration system is more efficient than any modern full flow system. “Newer” and “Modern” in this case doesn’t equal “Better”.

Good Call

I agree with the others, a by-pass system will filter out a smaller particulate, and will eventually filter all the oil.

A few years ago someone on the V8 Club forum took the time to measure the flow on a stock bypass system. He said at driving RPM he got about a quart per minute. If that’s true, entire quantity of oil would run thru the filter every five minutes of driving.

[tubman]

I have heard (I think I read it on this forum) that all of the oil passes through the filter in 11 minutes. These numbers are close enough to be believable and show the effectiveness of the stock system.

I think that was “51MERC-CT” . At idle it filtered all the oil in 11 minutes. I like using the stock system .......Mark

I have taken some notes from SAE papers
.001=25.4 microns
particles under 20 microns most harmful to rings and bearings.
Bypass filters typically filter 5 quarts in 10 minutes.
Full flow filter—
40% @10 microns
60%. @20 microns
95%@30 microns
97%@40 microns

Bypass filter—98.7% captured @2 microns

Most full flow filters have a bypass valve inside opening at 7-15 pounds pressure drop through the filter, most likely cold thick oil will open it at startup , then no oil is being filtered

[outsider347]

Most confusing!

4 yrs ago when I purchased my 40, didn't have a stock filter.
I posted a question on this forum asking about it
The replies for the most part " don't bother. They are rated to filter 10% , reality probably only 2%

Not trying to disrespect the the Gents that responded.
but
Does the element in the stock filter to a finer particle than a after market by pass filter?

What is the objection to the external system?

Anyone know where I can read about stock filter performance specs?

Thanks again Gents. We all know that a FH rebuild ain't cheep.
Trying to protect my investment.

If you insist on a filter then the stock bypass works very well for how our cars are used. The bypass filter removes much smaller particles than a typical full flow filter. The other thing that works very well at removing contaminants from the oil is changing the oil. I don't bother with adding filters to engines that don't have them. I do keep the engine in a good temperature range to avoid generating sludge (cold low speed engines like to sludge up). I also change oil when it gets degraded. Remember that oil that is breaking down or fuel contaminated flows very well through a filter.

[Rudolph]

They reckon the bypass system was a sales gimmick, the grit could pass through the bearings 100s of times before it ever made its way to the filter, I run the 95% flow system but change the oil often and only start the engine if I am going to do a couple hours driving

Rudolph, don’t believe everything you “reckon”.

[outsider347]

Ok I get it

Wondering if there are any FH racers out there?
What type of oil filtration system are you using?

Again, not trying to disrespect anyone
Simply looking for info

[Zeke3]

Charlie Schwendler is your neighbor, pay him a visit and pick his brain on the topic. I’m a fan of the bypass system.

[aussie merc]

nothing wrong with the bypass filter they work and are still standard factory equipment on many heavy vehicles so i would stay with stock just fit a quality element to the filter [ask the right questions and the element suppliers will tell you the micron rating of the element]Quality rules not price with filters

[Mart]

The other alternative is no filter at all.

Just saying.

Mart.

In addition to an engine oil filter, while you have the engine apart for a rebuild, you may want to consider a HIDDEN PCV system for you engine. Here is a link to a thread I started sometime ago. "It's a MIRACLE"

During WWII the military required a full flow oil filter, so, Ford came up with the66/95% system we have today. It's a simple system, which gets quie complicated by well meaning people. I used it because I could put the filter under the engine on a bracket behind the steering column . Makes it easy to change.

Its simply a matter of what one prefers to do. A bypass system is Okay. The 95 percent system is better. Those of us who use our Ford flathead powered cars a lot like myself prefer to use the 95 percent conversion the filter I prefer for the conversion is the Ford Motorcraft FL-1A.
Sure its a bit more work converting to this improved system but its not a difficult job for the average individual to do with some care and good mechanical skills.

My experience after driving cross country and back first time 6000 miles the second trip over 7000 miles most at highway speeds there was no internal wear what's so ever. Since I have driven my roadster over 100.000 plus miles so far I'm pleased with the longevity of the internal parts. An additional item that helps greatly as mentioned above is a PCV.

One needs to think about what's taking place in our engine's. While we know the cubic inches of the engine's size that same cubic inches is actually being pumped on the downward stroke into the crankcase. Thus the blowby and crankcase pressures are an area that's greatly improved when a PCV is added into the equation.

Thank You John.
This is what I am looking for

Here is the pcv system I put on my 8ba. I welded bungs on bottom of intake to draw vacuum from both side of intake, used a pcv valve off a 63 comet 260 engine.

You can use both systems— full flow plus a bypass
The Mercedes with a million miles in the ad only has a bypass filter and just a screen for full flow

[5851a]

One of the milk trucks I drove had standard filter on engine and a bypass system installed by a previous owner. Seemed such a waste since the engine was a leaking puking 6V92 Detroit, changed it's own oil every day. That Lubrufiner held about 2 gallons of oil.

Newbe here. 1950 Ford sedan - has a bypass oil filter canister, but not plumbed. Chromed and just sitting there looking all pretty but doing nothing. I'd like to use it but knowing next to nothing about the flathead, I don't know where to run the oil lines. Where can I get that info?

Thanks!

The last pic is your stock PCV system. If you search on google with Ford Barn in the search ( stock filter system On Ford Barn) you’ll get a whole day worth of reading.......Mark

Technical - HELP: oil fumes inside when running Flathead V8 | The H.A.M.B.

[40 Deluxe]

For what it's worth: The "1940 Service Data Handbook" that came with my 1940 sedan says to change the oil every 2,000 miles if not equipped with a filter. If equipped with an oil filter (original bypass type) change the oil "at 5,000 mile intervals. The filter unit should be replaced every 10,000 miles." So Ford must have felt their bypass filter was effective!
I think that a PCV system is a big improvement over the original road draft tube because the car has to be moving (probably 30 MPH or more) to create the draft at the tube outlet that pulls fumes out. When idling or putting around town there is no ventilation occurring and the oil gets contaminated with combustion by-products. A PCV system works well at idle as well as at speed.
