What is a potential consequence of an overheated engine continuing to operate?

An overheated engine continuing to operate can lead to excessive ring wear. The engine's operating conditions become less than ideal when temperatures rise beyond normal levels, resulting in increased friction and stress on engine components. The piston rings, which create a seal between the piston and cylinder walls, can suffer from excessive heat. This heat can lead to distortion or wearing of the rings, impacting their ability to perform properly.

In this scenario, worn rings can cause a host of issues like reduced compression, increased oil consumption, and even engine damage. While other options may seem appealing, they do not reflect the reality of what happens to engine components under excessive heat, making excessive ring wear the logical consequence of an overheated engine operating continuously.
