What are some causes of a ticking sound in 1984 corvette engine?

1. Worn hydraulic lifters. Lifters are small cylindrical devices that help to open and close the valves. Over time, the lifters can become worn out and fail to function properly. This can lead to a ticking noise.

2. Loose rocker arms. The rocker arms are responsible for pushing down on the valves. If the rocker arms are loose, they can cause the valves to vibrate, which can result in a ticking noise.

3. Bad camshaft. The camshaft is a rotating wheel with a series of bumps that control the opening and closing of the valves. If the camshaft is worn or damaged, it can cause the valves to open and close at the wrong times, which can lead to a ticking noise.

4. Carbon build-up. Carbon build-up on the valves or piston tops can cause the valves to open and close improperly, which can result in a ticking noise.
