The following publication (26 pages) consists of procedure on how to overhauling the Ford 9N Engine Block assembly. The engine shown here has been tanked (dunked in hot tank of cleaner), decked (top milled off to true up surface), and has been line bored. The crankshaft was recently re-ground. The rods were trued by the machine shop and new wrist pin bushings were installed and reamed. The pistons are used but in like new condition and most valve components and rings were replaced. This motor apparently had been recently rebuilt by the original owner who passed away. The previous (to me) owner purchased it and drove it home parking it where it sat many years before I bought it. While I got it to run the compression was poor as was the oil pressure. The compression problem was due to rusted exhaust valves and seats (from setting), and poor oil pressure due to a mismatched oil pump and rod caps. On the plus side the sleeves were like new and needed nothing.
