Chev 216 info

[Bob Carriere]

With a little more experience and having talked to a bunch of CMPers.... it would seem that the early military 216 used the available civy covers with the slits.... as soon as some sort of breather tube/cap was intalled the covers were no longer punched out for the slits. A variety of breather tubes/caps followed .... some original some which were added as extension to facilitate maintenance by non military owners.

Take care and thanks for sharing the info....
