Internally or Externally Balanced Engine?

Exterior Balanced Damper

Exterior Balanced Damper - Noticeable Weight Added

How do you know if your engine is internally or externally balanced? Externally balanced engines have a noticeable weight on both the damper (also called a harmonic balancer) and the flywheel/flexplate. Internally balanced engines do not rely on any counterweight on the damper (harmonic balancer) or flywheel/flexplate.
