Supporting Bob's solution, I know of four TR's that had this problem
during the last season -- breakup at about 5000. It is worse on cars
that have the engine mounted very solidly - that is, motor mounts
that have little cushioning. Four bangers have some bad vibes. The
vibrations from Offenhausers used to break the chassis.
