<VV> CAM WEAR

[Ray Rodriguez III]

Makes sense to me too.  Likely once the wear starts the hardening is pretty 
much gone on that lobe... and if conditions ate through the hardened metal I 
can imagine what they will do to the "soft flesh" beneath!

Smitty I agree with you.  I like to over-analyze things and wasn't giving 
any thought to the impression I might leave for newbies searching the 
archives in the future.  Oil being run in a Corvair engine should have ZDDP 
levels over 1000 ppm.  Break in is even more critical and proper additives 
and procedure should always be followed.
