As a V8 enthusiast I've been acutely aware of complaints regarding tappet noise and low oil pressure in those engines. Although I never worked on a 356 motor, over the course of compiling data for the site's online
Service Index, I was surprised to find similar complaints for this straigth eight engine.
WRT to this regulator valve, the bulletins only reference a problem of sticking, with redesigned assemblies developed for 18th/19th and 20th/21st Series.

Does anyone know why the Tappet Oil Regulator was discontinued in the 1948-1954 engines?
The answer can be found in the
1946-1950 Service Manual, under "Section V - Engine" (specifically, pg. 35). Basically, the valves were eliminated from this engine in favor of some new oil passages, effective with the 22nd Series Custom 8. However, I don't recall any bulletin recommending a retrofit for earlier Series.
I can't offer any advice on where to locate these parts - not even a complete valve assembly.
Perhaps others can shed some additional light.
