Chevy Impala Valve Covers & Parts

Whereas the oil pan covers your Chevy Impala’s engine from underneath, the valve cover provides protection from above. These two components carry out largely the same functions while sealing the lubricated area and preventing contaminants from getting inside the assembly. And while the pan has an oil drain plug, the valve cover provides the filler neck with the cap. Valve covers of most modern engines are made of durable plastic. Not because it’s inexpensive, but because this type of material doesn’t expand when heated as much as metal, and its strength is sufficient for this application.

A valve cover and its gasket are highly vulnerable to overheating. Even an insignificant deviation from normal engine temperature often badly affects these two parts while hardening the seal and deforming the cover. As a result, the engine oil starts to leak which can have serious destructive consequences. Typically, the solution lies in the replacement of the damaged parts, which can be rather pricey if you opt for GM’s original equipment. However, you can save a lot of your time and money by taking advantage of our Chevy Impala valve covers & components.
