Default Re: Oil: To filter or not to Filter

Around 1940 I think they were using the filter return that dumped into the fuel pump stand. This caused some issues with increased oil vapor out the breather. Then they switched to a return that connected with a banjo fitting and hollow bolt to the timing cover. Later the return went to the oil pan and then a fitting is the lower edge of the block near the oil pan.

Attached is the diagram for the timing cover fitting. That might be the most correct for a 40, but not positive about that.
