Last week on a Tuesday I drove from Portland to Hood river to help in the dismantling of the OX-5 engine. I met Bill at the museum and the two of walked out to H-1. When we entered the hanger the engine was on the engine stand and the hanger felt like a refrigerator. Bill is an expert in aviation engines and my experience lies in antique car engines so i followed his lead. The first step was to remove the rocker arm assembly. That was interesting in that they were connected by a water jacket pipe. One valve was actuated by a pulling push rod while the other valve was opened by a pushing rod.
Next the intake manifold and exhaust manifolds were removed. Our objective was to check the cylinders for wear.
Finally the number one cylinder was removed and Bill used a device to check the trueness off the cylinder and the amount of wear it had. The cylinders looked good.

Next up was to remove the oil pan and oil pump to check the rod and main bearings for wear.
