oil canister restrictor fitting
A friend is putting together a 35 flathead v8 and it has a standard canister style oil filter. My 51 8ba has a brass restrictor fitting on the inlet side of the canister, so my question is have they always used this setup and if yes he'll have to add this to his piping. I know from past threads the fitting is 1/8th npt mail to female with a .065 orifice. Thanks for any help.

Re: oil canister restrictor fitting
Oil filters were not introduced by Ford until I believe '36 or possibly even '37. I may be wrong about that and if so, perhaps someone can chime in. Regardless, the oil system of these old Ford engines is the same and as such requires that restrictor.

Re: oil canister restrictor fitting
Sometimes the restriction is in the fitting at the rear of the block and sometimes it is in the fitting on the oil canister inlet.

Re: oil canister restrictor fitting
Forded thought a lot of their bypass filter system. My 40's original owner's manual says to change oil every 2,000 miles without an oil filter, and change every 5,000 miles when equipped with the optional bypass filter.

Re: oil canister restrictor fitting
Ditto what flatjack said. Mine has the restrictor hole in the return tube.

Re: oil canister restrictor fitting
Those first optional bypass filters offered in the mid 30s were not like the later head mounted filters with the removable top. They were in a can form but I think they were a throw away type can. There are some threads on here somewhere that have photos. The earlier engines had even less pressure output than the 8BA types so the restrictor is even more important in them.
PS: I was wrong about it not being disassembleable but the whole cartridge has to be replaced each time. Post #3 in this thread has a diagram. http://www.fordbarn.com/forum/showth...936+oil+filter Last edited by rotorwrench; 02-21-2017 at 09:58 AM. |

Re: oil canister restrictor fitting
You can also convert the bypass canister with a spin on bypass used still on many early forklifts and easily purchased.No mess changing that one at all and readily available as opposed to sometimes hunting down the cartridge for canister.Doesn't require metered .060" orifice in the line.

Re: oil canister restrictor fitting
this one was on the back of the filter housing you see in the photo. the restrictor orfice is on the inside end, outside just looks like a brass fitting for a flared line. a 1/16 drill bit will not go in

Re: oil canister restrictor fitting
This subject comes up often and a search will provide many posts on this subject. My usual reply is that our 46 filter canister has a restrictor hole in the standpipe and also a restrictor hole where the return line attaches to the pan. No one has ever replied to this pan return restrictor??

Re: oil canister restrictor fitting
old ford that is an interesting set up for sure. it made me go look at this motor here. i had thought when i posted the photos above this was a factory installed filter. dark blue 59ab motor from mars, or what ever. the fitting in the pan (the drain lets call it) is not restricted, just a plain brass fitting for 1/4" double flare, like brake line. it is however drilled into the dip stick boss. i have some other oil pans that have they're own boss for the drain, so perhaps this was added on? this is all nit picking, the op needs a restrictor , .065 some where. 1/16" is 0625, the next normal thing is size 51 drill, .067. so, silver solder the end of a brake fitting and drill it, or screw a brass screw into the line and drill it to either the common too big or too small size, i do not think it will matter, or have your local heating and ac place drill it correctly with an orfice drill to .065

Re: oil canister restrictor fitting
If you are looking for a modern brass fitting with a restriction hole in it turbo charger oil fittings are available.
