Re: oil filter, fuel pump lines, spark plugs, fan belts

The vacuum is used to power the windshield wipers, the Bijur chassis oiler, and the power brake booster. The vacuum source is the intake manifold with the fuel pump booster in series to provide vacuum during hard acceleration.

AutoLite 306 plugs are appropriate for this engine, available at most any decent auto parts outlet. (CORRECTION - 308, not 306)

The oil filter and oil heat exchanger is a unique one-year only arrangement for the 1934 Eight and Super Eight. Its a full-flow system new for 1934; the entire output of the pump goes first thru the filter and heat exchanger before it gets to the engine internals so it's vital to know what steps were taken when the filter was removed to maintain the full flow oil circuit to the main gallery without which you'll trash you engine. The filter is a Purolator L-6 (1 year only) and a repro is available from R&A which uses modern cartridges inside. In addition to the missing filter it would be helpful to what other parts of your system are missing or modified. One problem as the components have aged is the failure of the heat exchanger core, though it's easy to make a shunt to replace it.

As we now have multi-vis oils you can do without the heat exchanger but if the housing is missing and replaced with a cover plate you'll have to alter the baffling inside the water jacket plate or the rear cylinders will starve for coolant. Or replace the water jacket side plate with either an earlier or later style.

You can just continue on without an oil filter and change your oil more frequently, but this requires modifications to maintain the oil flow to the galleries. You say your canister is missing, how has your oil flow been re-routed?

Fan belts are Gates 11A0990; not essential but get a matched set if you can.

I suggest you take time to read thru the 1934 Service Letters which gives a good overview of the new oiling system for the 11th Series. It will be easier to discuss it with you when you have some good understanding of it.
