In the latest units, the ball bearing is sealed and should not be able to spill its guts into the engine. Apparently there's no way to tell when the bearing is ready to go.

This happened to a friend on a 617, but the valve was not damaged. The finger operating the valve is softer metal so it bent. No head removal. He replaced the finger, reapaired the vac. pump and was back in business.
