Well I measured .. I borrowed the micrometer .. with dimensions of 94.9mm And should one have tollorantie of 2 hundredths I believe ... but there went that far over it as I see it .. at cylinder 7 is the correct one hundredth smaller .. vandaaar perhaps the scratches?
in each case .. I suggest not bounce him honing drilling. I only new piston springs and bearings should be sharpened crankshaft bearings where he touches.
