[QUOTE="passenger0_0, post: 23791, member: 208"] Can't say there's anything wrong with using Specialloids or Omega for that matter as long as they are either new or really good condition and been crack tested. I certainly would not go for ceramic coating as this reduces heat flow through the piston crown and raises temperatures in the chamber to potentially above critical levels. I found this out in a racing Triumph triple engine many years ago where the spark plug overheated and so much molten piston aluminium blew out the inlet trumpet that all slides jammed open. My recomendation would be to repair the damage, even fit a replacement Specialloid or Omega piston but restore the liner to head seal. By the way - have you checked that spark plug depth I mentioned earlier? Cheers David [/QUOTE]
