Heads, pistons, damage?
Got the head off yesterday and there is a small amount of damage to the top of number 3 piston.
There is also a similar matching damage on the cylinder head. All of this seems to be caused by a small alloy washer that somehow got into there.
Meanwhile, there are fewer "clean" threads on number 1 plughole than on all the others which implies to me that there have been fewer actually "biting" - hence the plug being blown out some time ago!
Good job I have a head being reconditioned I think.
I still need tog et the front off the engine to find the missing sprocket bolt and half moon locking tab - hopefully, they are not in the sump.
