What are Rocker Arms?

Rocker arms are components of an internal combustion engine that transfer the motion of the camshaft to the valves. They are typically made of steel and consist of a lever arm, or rocker, that pivots on a shaft or stud and is connected to the valve stem.

Should Rocker Arms Move Side to Side?

In general, rocker arms should not move side to side. If they do, it could indicate a problem with the engine such as worn bearings or loose mounting bolts. It could also be caused by excessive valve lash, which is when there is too much clearance between the rocker arm and the valve stem.

How to Check for Side-to-Side Movement

To check for side-to-side movement in your rocker arms, you will need to remove the valve cover and inspect each rocker arm individually. Look for any signs of wear or looseness in the mounting bolts. If there is any play in the rocker arm, it should be replaced immediately.

If you find that your rocker arms are moving side to side, it is important to have them inspected by a professional mechanic as soon as possible. This issue can cause serious damage to your engine if left unchecked.
