When they built Jeepsters, plastic was the next big thing. Unfortunately, it was also the new thing and plastic in automobiles and its interaction with automotive fluids was not thoroughly understood. We found plastic in various odd locations in this Jeep that had failed spectacularly, but a plastic-covered aluminum timing gear was a first for us. It was missing plastic and aluminum in two spots, and we are amazed that the engine still ran and the chain didn’t skip teeth.
