477.340 Elring Cylinder Head Cover

The Cylinder Head Cover from Elring (MPN: 477.340) is sourced from Germany and has supplier-listed dimensions of 225 x 380 x 780 mm. It is typically used within the Engine Parts > Heads & Valve Train > Rocker Cover category of automotive replacement parts.

Positioned atop the cylinder head, they enclose the rocker arms, pushrods, and valve springs. Typically constructed from aluminum or plastic, they feature integrated baffles to manage oil return and reduce oil aeration. Gaskets or O-rings provide a static seal between the cover and cylinder head, maintaining compression and preventing contamination. Modern designs often incorporate PCV valve mounting provisions for emissions control and crankcase ventilation.
