Chev 216 info
 

I spotted this in a Chev manual and I learnt a new Chev idiosyncrasy

Valve covers....???
 

Bonjour Mike....

....would you have a nice picture of the valve cover on the original 216..... from that book of yours????

I have these engines yet to be identified that maybe 216 or bigger..... the valve covers are mounted by 2 central studs/nuts combination ...
BUT.. they have these tiny slits about 1/8 of an inch high by 1 inch wide...and about four of them. Some kind of opening that probably replaces the breather caps of later Chev 6...... It does not seem to be a good way to protect the innards of an engine but in 1940 ???

Eventually I will get down to scrapping the cooked grease deposit and find serial numbers and casting numbers for David H.

Your help is appreciated.

valve covers
 

Most of the civilian 216's had the valve covers with the little slits. So did the early 235's. I'd never seen a 216 without the slits until I got a military one.

Valve covers...
 

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....
