Ron brings up a question I have always wondered about--the block cam bearing 
area (no real bearings of course, just the block itself where it supports the 
cam.  Outside of checking tolerances when an engine is apart I have never had 
to reject a crankcase because of wear at the cam bearing area.  I have always 
changed oil regularily and all of my engines have high mileage with good oil 
pressure.

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)?
