Cam carriers and cam covers are components related to the camshaft in an internal combustion engine. They play important roles in protecting and housing the camshaft, which is responsible for opening and closing the engine's intake and exhaust valves.

Cam covers, also known as valve covers, seal the camshaft and other components in the valve train to prevent oil leaks and contamination. They typically have gaskets that ensure a tight seal between the cover and the cylinder head.
