Rods and Pistons

My follower recently complained that I was not doing an adequate job of blogging of late. So, Peter, here's some photos of some really nasty rods and pistons. The engine was seized up and after great quantities of WD-40, I was able to tap the pistons out of the block. Numbers 3 and 4 were particularly stuck and finally came out several days after the others. Nasty. Two of the pistons are of a different manufacturer than the other four and none are original. The standard 8 to 1 compression pistons have a small dome shape in the center of the top and it does not reach the edges. These are apparently a higher compression ratio since the entire dome is spread across the entire top and shows relief areas for the valves.




















It is probably hard to see here, but the number 3 and 4 rods themselves are corroded and pitted. Both pistons and rods will need to be replaced as a set.
