Yes, using starter fluid in a diesel engine can indeed cause damage, particularly to engines that have glow plugs or other pre-heating elements. The highly combustible nature of starter fluid increases the risk of pre-ignition or even potentially explosive combustion inside the engine's cylinders, which can lead to piston or rod damage. It's best to consult the engine's manufacturer or a professional before using any starting aids to avoid costly repairs.
