The chambers edge around the right intake valve has changed a tiny bit, so technically you are correct,

Why did it change??

Chamber edge... this time cylinder 3. On top is the chamber edge before any work, you can see the old gasket, so that edge "sat" in the combustion chamber



Note how significant a flaw the edge of the chamber actually is.... when measured... it is .48mm "tall", and it is .73mm "deep", or sticking into the chamber is a sharp edge. So how significant is it...??? see the little green arrow, that arrow shows where I placed the dental pick....




Edges are NOT GOOD, they promote detonation, and this one stick "in" like a sore thumb


So... that is why the edge of chamber four around the right hand valve now has a bit more room to breath....


More to come......
