Question

Tech A says worn valve lock grooves may cause the valve locks to fly out of place with the engine running, resulting in severe engine damage.

Tech B says worn valve lock grooves may cause a clicking noise with the engine idling

-A
-B
-Both
-Neither

Answer 1

Worn valve lock grooves can cause the valve locks to fly out of place, resulting in severe engine damage. While they may not directly cause a clicking noise, they can impact engine noise.

Step-by-step explanation:

Tech A is correct. Worn valve lock grooves can indeed cause the valve locks to fly out of place while the engine is running, resulting in severe engine damage. This is because the valve locks are responsible for keeping the valves in their proper position, and if the grooves are worn, they may not be able to hold the valve securely in place.

Tech B is incorrect. Worn valve lock grooves do not directly cause a clicking noise with the engine idling. However, worn valve lock grooves may affect the valve operation, and this could potentially lead to clicking noises or other symptoms, depending on the specific cause of the problem.

Therefore, the correct answer is Tech A - Both, as worn valve lock grooves can cause the valve locks to fly out of place and may also have an impact on engine noise.
