Okay, look again at the Bentley manual drawing. It shows the oil moving
along the outside of the plugged filter, then pushing open the
spring-loaded relief valve at the bolt, pushing it toward the engine
block, and thus getting around the plugged filter. The valve is moved
off it's seat from oil pressure that is pushing from outside the
paper filter element.
I'm saying the Bentley drawing shows exactly how the overflow valve works.
