Ringo's Rank Cylinders

A couple of hours in the garage last and I could peer into each cylinder. What I saw, while rather unpleasant, was not as bad as it could have been. While there was oil and crispy burnt oil residue in at least four of the cylinders, I didn’t see any scratching on the cylinder walls. This evening’s task is to remove and mark each cylinder jug, measure the bore’s condition in each and determine if replacement is required or if a simple honing of each will get the job done properly.

To get to the point of removing the heads so I could see down in the cylinders, I had to remove the generator, fuel pump, all the sheetmetal, the fan, and the oil cooler before pulling off the valve covers, unbolting the rocker arms, removing and carefully storing the pushrods and rockers in a box with each rod poked through its position in the lid to ensure each went back into its original location. With the rockers off, the studs (which are the lower head nuts) came off followed by upper nuts. I had a couple of studs that wanted to come out with the nuts, but a well-placed vise-grips kept them from turning. By jiggling each head, it eventually slid off over the studs and the associated photos could be taken. Nasty, huh? More photos here.
