The valve cover is responsible for sealing the internal workings of the engines' top end. Most vehicles require a replacement gasket at some point or another and newer models have plastic valve covers that get brittle and crack with age.
Plastic valve covers are known to warp and crack over time. After numerous heat cycles, plastic becomes brittle and more susceptible to failure. If your B46 / B48 engine has higher mileage and you've noticed vacuum leaks, oil leaks, or PCV failure, this replacement from Elring is a great choice to address the issues and keep your engine leak free!
