Nice Vice
When i have taken all 4 pistons out they are all the same so dont think its dont to fuelling and is more down to the plug tip coming of and hitting the piston . Just my thoughts .
I'd bore it to out new pistons and rods and put it al back in if it was me or the 2.0 JDM block you have been offered is the cheapest option and would support the current level of the car .
