Our race at AMP was cut short due to a sudden loss of oil pressure. We tried to diagnose at the track, but the crack pulley was tight and the oil level was correct so we knew a removal and disassembly was next on the diagnostic list.
Back in the shop, I pulled the engine and dropped the oil pan. Inside, where it should not be, was part of the oil pick up tube. The remainder was still bolted to the block.
