Oil Filter Model A on timing cover
 

Hi Specialists
I have a model A Rodster pickup 1929 76A with the Oilfilter on the Timing cover.
Its connected on the plug at the Oilpump Shaft. High pressure side.
The Oil goes thrue the Filter into the timing cover.
Its the Filter with the number A-6705

I have the Question how this system is working?

I suspect the oil goes from the pressure side of the oil pump through
the filter on the steering housing in the engine So that is parallel to
the previous way. I'm afraid that then oil volume is missing in
the Valve Chamber Oil inlet. But It works for years. Get the Oil over the Steering cover also to the Valve Chamber Oil inlet?
Can anyone explain to me?
Kindly regards

Re: Oil Filter Model A on timing cover
 

It is called a by-pass system. Part of the oil goes through the filter and the remainder goes through the original route.
This type of system was used on many makes of cars for many years until they switched over the the full flow system which is much better.

Re: Oil Filter Model A on timing cover
 

It is filtering a portion of oil continuously, it is fed by a side tap, so all the oil is filtered over time. Most of the oil from the pump is going into the valve chamber. It is a proven system so you don't need to worry.

Katy beat me to the draw!

Re: Oil Filter Model A on timing cover
 

Has anyone also checked whether the filter is actually flowed through? (Slicing and dirt inspect after 2000 Miles.)

I doubt the open oil-pressureless system because the backflush valve in the filter cartridge needs about 3 - 3.5 PSI pressure to open the filter inlet!

Re: Oil Filter Model A on timing cover
 

Since the oil is also flowing to the valve area the valve is not needed & could be disabled.

It works fine with the filter valves, I have had one for 27,000 miles.

Good morning,
it is hardly possible to remove the rubber flutter valve. But I have just read that there are filter cartridges without a valve. Care must be taken when shopping.

I think the other filter variant is the better one, in which the pressure oil in the valve chamber line is connected to the filter line. (That's how I did it on my Cit Traction.)


Hi John, did you open the filter and saw the pollution?

Re: Oil Filter Model A on timing cover
 

Some opt for a "remote" oil filter installation that puts the filtered oil into the front of the valve chamber. See post #11 in this old thread: https://www.fordbarn.com/forum/showt...lter&showall=1

Re: Oil Filter Model A on timing cover
 

I just bought this filter but it is not installed yet.

Does anyone have experience with this one?

I have that kit installed on mine for the last 5 years and it works just fine. When I installed it I loosened the return tube to see if there was a restriction due to the filter and there was none. The oil is flowing and normal volume.

Re: Oil Filter Model A on timing cover
 

I used one of those but the copper tube didn't fit like it was supposed to, I fabricated a tube that would fit using the supplied fittings and the filter seems to work fine.

Re: Oil Filter Model A on timing cover
 

I believe that that one ends up mounting teh filter on an angle, and can be messy getting it off and on. An Adapter is available so the filter is not on an angle.

Katy, thanks for helpin' hint! -


I tend now to the valve chamber lid version. I am currently restoring the oil pump. A gear oil pump that turns without play can generate very high pressures. There are also filters with a particularly low backpressure. From a technical point of view, no nominal loss of oil flow is to be expected.

But if I understand correctly, the filter system fits only on the modernized cover plate and not on the 1928 version.

Re: Oil Filter Model A on timing cover
 

That is correct you will need the later style oil return pipe for the modification. the bypass filter is still a good option.

Allgairfan,I do not have the same filter in your link. Post 6

I have this filter which does not take oil at the oil pump.

I do not know about yours.

J. Franklin,

does this only affect the length of the return pipe? Shortening or extending the tube is really no problem.

Re: Oil Filter Model A on timing cover
 

You can modify the tube, the ends are the same and are a soldered connection.

Re: Oil Filter Model A on timing cover
 

Thanks at all for the filter-idea and the many hints! I have chosen now the pressure oil version 'Bratton's oil-filter-kit'.

Re: Oil Filter Model A on timing cover
 

I have 12,000 mile on the kit shown old 31 and works great.After 1000 miles oil is starting to get dark.

Re: Oil Filter Model A on timing cover
 

Here's how the tube on my CCPU was extended, It's kinda neat as one can see the oil flowing.
