Question

Mechanical (solid) valve lifters produce a clatter, or clicking noise, as the valves operate.

A) True
B) False

Answer 1

True. Mechanical valve lifters do produce a clatter or clicking noise as the valves operate. This noise is caused by the contact between the cam lobes on the camshaft and the lifters. When the cam lobes push against the lifters, it creates a mechanical force that causes the lifters to move up and down, which in turn opens and closes the valves.
