The most likely scenario is the first one, that the oil burning
is what caused the problem with the valves.  In either case, you need
to take a look at the piston rings, so I'd set aside some weekend
time for hauling the heads off.  Why didn't he replace the valves on
the rebuild?  That's a heck of a shortcut...valves aren't that expensive
(that is, when you only have to replace them ONCE).

Cheers.

All,

Thanks for the help,  During the rebuild the valves were ground but not 
replaced.  According to the rebuilder he says these valves or others
like 
them in hondas have an issue where they may chip and then break a
portion 
off completely.  I did not see any evidence of interference.  Oddly
though 
the valves had a lot of buildup (carbon i think) on them but the piston
was 
only slightly discolored.  Other pistons had slight  carbon buildup on
the 
pistons but none on the valves.  The rebuilder did not offer to rebuild.
I 
have had work done by him in the past and have not had issues so I am on
my 
own on this one.  Should I pull the piston for the bad cylinder and
check 
for broken rings?  I guess what I am asking is did the oil burning cause
the 
valve problem or did the valve problem cause the oil burning?

Again, thanks for the help,

Coy
