- Engine Protection Where It Counts — The head cover shields valve train components from debris, moisture, and contamination — critical on saws and generators operating in dusty or wet jobsite environments.

The head cover sits on top of the engine cylinder head and encloses the valve train, including the rocker arms, valves, and related components. It forms a sealed barrier that keeps oil contained within the top end of the engine while preventing outside contaminants from entering. A cracked, warped, or missing head cover can lead to oil leaks, accelerated valve wear, and engine damage — making timely replacement essential for maintaining engine health and preventing costly secondary failures.
