I dropped into the mechanic today as he has begun the strip down of the engine. At this stage it will need new cam followers as the hardened surface on some are worn, I hope the cam is OK. The water pump is well and truly stuck to the head. I didn't get a chance to measure the bore size to see if it is still 1255cc or 1296cc. I will be back tonight and measure it.
I measured the bore tonight and its standard 1255. It measures 74.30mm.
Bore looks OK but will be honed.
Box of bits.
Cylinder head with the water pump still attached.
