i’m rebuilding my 4.7 engine it had a a misfire on cylinder 1 and excessive crankcase pressure so i though it would be a piston ring i took it apart and the piston was missing a really small piece under the oil ring and it scratched the cylinder walls i honed the cylinder walls and cylinder 1 has scoring when i pass my nail on it i can feel it but it won’t get stuck on it i just feel it im wondering if i can run it like that and just throw new rings and new pistons im doing this as a learning experience im not tryna have anything perfect im just tryna drive the truck daily without any misfiring don’t matter if it consumes a small amount of oil
