If you look closely at the picture you can still see the seat behind the valve. The wear pattern looks like it probably started with the seat working loose and wobbling in the hole. Once it came loose<VAR id=yui-ie-cursor></VAR> the seat was probably traveling with the valve, but provided enough seal when it closed for the cylinder to keep working.</SPAN></div>
