Where exactly should I look for my problem? Inside the push rod side cover?

I am not sure what the flow path is supposed to be on this engine so I am not sure which lines to check and what I should expect. I have a larger line, I think it is a return line coming from the block to my external filter mounted on the distributor side of the block. I have a line that I think feeds this filter coming from the top of the filter and connecting to the front of the block, in the bottom corner (Manifold side corner) by the timing cover. This connector has 3 passes. One threads into the block (Male) and then I am left with an L shape with a female connector on either leg of the L. The line connected to the top of the filter goes to one of the taps and the the other tap is connected to a line that goes to the head.

Does any of this help?

Thanks,
Tom
