It took a while to figure it out but it looks like the timing gear cover filter is a bypass filter not a full flow.
John, your comment basically confirms this. And I am very familiar with bypass filters on my diesels.
Just pulling the plug out and putting the line for the filter in can have one of three consequences. 1 - it will divert all or most of the oil through the filter and starve the valve cover cavity. 2 - Minimal or no oil will flow through the filter. (oil will flow through path of least resistance...pump outlet in valve cover cavity.) or 3 - Oil will go to both and the world will be a happy place.

I concur that this would not be the recommended way to add a filter. First is it not doing full filtering and second, it can starve the engine of oil.

The valve cover filter would be the way to go since it does not change where the oil is going, it just runs it through the filter as it comes out of the pump. If the filter were to become clogged the pump is capable of producing the pressure to push the bypass open so oil starvation should not be a concern.

Decision made...gotta pull a few pennies together ....

Thanks for all the input.
