What is  the experience of other VVers with crankcase wear at the cam bearing 
 
area?  With age and high mileage when can one expect to have an out  of 
tolerance crankcase (or half)?




Bob,
I've built at least 100 Corvair engines in the last 30+ years and as memory  
serves me, in all of those engines I've only had to reject one block for cam  
bearing wear.  And that was an engine from a dune buggy that had eaten a  lot 
of sand.  I think the cam bearing areas wear so well is because the cam  is 
being pushed from two sides only and equally which reduces the pressure on  the 
cam bearing areas and the cam gets a good deal of oil pumped into that  area.  
IMHO
