<VV> Theoretical recommendations.

[Charles Fregeau]

Yep, it was an early 62 (bought on Dec 17, 1961 and the 67,370th produced at
Willow Run for the 1962 model year.)  

 

So one of my theoretical changes is to swap out the original engine for a
later one or just replace the valves with better (stellite faced ones)?
With a later engine, say a 64, I also get the lighter fan and at some point
I get an alternator instead of a generator, too.

 

The mechanic we had apparently did not know of the stellite facing on the
later valves.  He blamed the need for valve grinding on the lack of airflow
around cylinder #1 causing the valve to burn.

Charles,

Because they were leaking and needed to be ground?

 

Well the real reason was because some of the early Corvairs used inferior
valves. Chev made many changes during the early years to correct various
problems. Bad valves were one, and a poor design that didn't allow the
valves to rotate in use was another. The first problem was corrected by
using stellite faced valves. Your car apparently was before that change.
Valves were later rotated by the four-bead design.
