We tore it apart, inspected the block and heads for any damaged parts or cracks, then hot tanked everything.
The cylinders were bore and honed to the proper finish, another hot tank, then a coat of paint. Meanwhile we work the cylinder heads, grind valves, cut seats, resurface, clean and assemble.
Short block rebuild in progress. No pics of the bore and hone, but you can see the nice finish on the block and the pistons have a good fit. Engine rebuild kit with new pistons, rings, full gaskets, bearings, thrust washers, oil pump and timing kit.
Time to add those oil injector tubes with perfect alignment and crank clearance. They’re a pain in the ass!
