need some advice regarding diagnostics for the pistons and valves. I have 
removed the carbon from the piston and I am wondering if I should replace the piston 
as the piston top surface got slightly scratched. Does this matter at all? 
The scratches are very minor but you can see some shiny Aluminium in the 
scratches. Should I have the pistons inspected or just replace them with new ones or 
don't worry? Or can you sand the piston?  >>


What did you scrape the carbon with?  If they're only minor scratches I'd 
tape up the pistons and have the tops bead blasted.  DO NOT bead the ring 
grooves, it affects ring-seal and not in a good way.
