Another question for the experts!
I removed the #3 piston in order to examine the possible damage to the piston top where it whatever the foreign body (bodies) has been touching it and found some other somewhat disquieting evidence that all is not right.
If you have a close look at this photo which shows the side of the piston

you will see evidence of it rubbing on the side of the bore. The rubbing is immediately above the conrod.
Well that is what it looked like initially but further examination of the bore itself showed quite a nasty little burr just above the red arrow head here.

The question has to be what has caused this? It has obviously occurred after the block was bored and honed. Is it linked to the problem which has caused me to take the head off or is this just yet another problem which I have to resolve?
A final question, do you all fit new conrod nuts every time you take a conrod apart? I am unlikely to find conrod nuts here in this country and if I have to bring in a set, it is another delay of at least two weeks.
