So here is the question everyone my Y block has a minor drip from the rear main so minor I do not care, but there is oil running from the top of the block down from the valley pan back of the block area.  I cannot see where it would be originating from. Any start points to help me locate the leak spots?

Valley pan, valve covers, rear intake flange bolt hole on the heads needs a short bolt - too long and it contacts the pushrod

older distributors that have no O ring ,like others the valley pan is the biggest issue
