There are all sorts of cam followers out there. OEM were hollow non adjustable types. The Johnson adjustables were aftermarket and some are hollow and some are not. There have been every sort of tappet tried by hot rodders. From the mushroom type to the locked roller types. Most all survived without further oiling but some created a lot of wear to the bores.
