[alfa] Rebuilt Alfetta Engine Officially Broken In

["Korolyshyn, Dan Mr. DAC DPW ENGR RESOURCE MGMT BR" <Dan.Korolyshyn@xxxxxxxxxxxxxxxxxxxx>]

IMHO, it is not just the bearings and rings that need a slow 
break-in period, for engines other than engines built strictly
for racing, but also the valves and guides, cams, chains and 
gears, oil pumps and water pumps, etc. that need a period for
mating and sliding parts to wear in slowly rather than roughly
in order to have a finer grained mating/wearing surface for longer
life expectancy.  I would suggest following Alfa's recommendations 
which are found in the owner's manuals.  Alfa also says to vary the
engine speed during break in which is very important.

I've seen a spun bearing on a newly rebuilt Alfa motor that was revved
too high too soon.

I always use the methods Glynn told me to use, which might be more
conservative than what Biba said.  But it's always worked fine for me..
