Hi

The method my professional mechanic friend uses to isolate the location of knocks is to use a metal rod, one end against the oil pan, the other to his ear. With the engine idling, he moves to each bearing location, listening for sharper knocks, notes any differences. It usually works quite well.

Although he hasn't had to diagnose any flatheads lately, it also works on their lifters. Even overhead valve-train knocks are easier to isolate this way.

Hope this helps.
