I have found that the gasket between the lifter assembly and the cylinder block can shrink, this opens the pressure/supply hole to the drain cavity in the lifter block.

This allows some of the oil intended to go through the lifter bores and lifters to go directly to the drain to the engine sump.

I made new gaskets, this quieted my ’33 engine’s lifters.
