Valve covers are components that enclose the upper part of the cylinder head, protecting the valve train mechanism and retaining oil within the lubrication system. The cover shields camshafts, valves, and springs from contaminants, while also, together with its gasket, maintaining the cylinder head's seal. In many modern engines, the valve cover integrates additional components, such as the PCV valve (oil separator) of the crankcase ventilation system. A properly functioning valve cover directly impacts engine sealing and the correct operation of the ventilation system.

A damaged valve cover exhibits characteristic symptoms: oil leaks from under the cover, oiling of spark plugs and covers, increased oil consumption, and in the case of an integrated PCV valve, also uneven engine operation, whistling of intake air, or problems with crankcase pressure. Cracks in the material, warping of the surface, or a damaged PCV membrane are reasons why a faulty cover should be replaced with a new one.

In this collection, you will find valve covers – made of plastic and aluminum, in versions with integrated PCV valves and gaskets – suitable for popular makes and models of passenger cars and light commercial vehicles. We offer replacements from trusted manufacturers, which, in terms of workmanship quality, sealing, and durability, correspond to factory-fitted parts. In our store, you can also complete other cylinder head and lubrication system components that work with the cover, such as the valve cover gasket, spark plug well gaskets, mounting bolts, and ventilation system components.

Each valve cover must be matched to a specific car model and engine version – before purchasing, it is worth verifying the part number to select the correct replacement. When replacing the cover, it is advisable to also replace the valve cover gasket and spark plug well gaskets. We offer valve covers at competitive prices, with fast delivery.
