Analysis

The pilots were participating in a grand prix air race. After a normal preflight, they took off & crossed over the arpt for race timing purposes. A climb was begun on course, and a short time later, the engine began loosing power. The aircrew turned back toward the arpt, but the engine began to run rough, then quit. During a forced landing in a muddy field, the nose gear collapsed & the acft stopped abruptly. An exam of the engine revealed that a connecting rod had failed & punctured the crankcase. Bearing damage was evident thru-out the engine reflecting lack of lubrication. Two magneto drive cushions were found blocking the oil sys pick-up tube. These were in addition to the two which were properly installed in the magneto drive sys. An opening between the accessory section & the oil sump would allow the cushions to enter the oil sump.
