The shop number is 205. Interestingly, this engine seems to have some problems due to the rebuild process. The engine has almost no perceptible wear. It has an oil contamination problem though. Small scores, and embedded particles in most bushings. As of today, I have all accessories apart. The problem seems to be a large wad of sand or other abrasive that was left in the fuel pump extension. Also. the oil filter motor was never conected to an oil supply, and the manual knob was still lock-wired. In it's short service life, the engine also ate a small piece of metal. Probably a screw. The suction side of the impeller is all banged up. After that, you can follow the progress of the screw through the whole engine by the marks it made. It ended up in no. 8 cylinder, and chipped a couple of edges off the piston before it was finally spit out. I read an article once stating that most aircraft engine failures in military aircraft (WWII era) were caused by foreign materials, mostly rouge, left in the engine during manufacture. Jesse.
