I even found bits of destroyed journal material in the oil filter fitting valve – see the triangular bit on the right of the valve opening.
I pulled two frost plugs and found very little in the way of corrosion crud. I’ll let the block dry out completely and then use high air pressure to blow out any rust residue.
The bare block and the starting point of the rebuild 🙂
Using the ridge reamer I removed all the ridge material from each cylinder leaving a smooth surface for my hone.
With the ridge cleaned up I checked the top and bottom wear. Each cylinder showed less that .0005 – that being the max acceptable.
Next: honing the block.
