I don't think the filter return does much for the chain directly since filters were an option and not on all engines. I believe the return drops into the lifter valley and while there may be an opening into the chain cavity, if any gets to the chain it is incidental. The chain is oiled by the intermittent squirt from the cam uncovering the hole in the thrust plate every revolution.
