As an aside, I had a timing belt fail and crash the valves without the belt
breaking.  I had a late '80s Nissan 200SX and the front camshaft seal was
slowly weeping oil, soaking the belt. It eventually softened the rubber so
that as I accelerated up the Bay Bridge late on a Sunday night, the camshaft
drive wheel spun the teeth off the belt. Getting towed back to Baltimore at
midnight on a Sunday night is no fun.
