Roush Valve Covers
Valve cover works as sealant that keeps oil in the valve train from leaking out the cylinder head. As the oil is pumped up through the pushrods and dispersed underneath the valve cover, the rocker arms are kept lubricated. Holes in different parts of the engine head where the oil circulates are sealed by the valve covers. If there is a failure in the function of the valve cover, the rocker arms would have shortage of lubricant. There are two types of oil spills—a seep and a leak. They differ because a seep is a slow seepage of oil that does not produce a drip; on the other hand, a leak causes a drip of oil when the vehicle is parked. How does oil spills occur? It is the valve cover that creates these leaks and seeps. Valve covers are a common source of engine oils seeps and leaks. Good thing there are replacement covers like Roush valve covers. Corrosions, warping and defects on the valve gasket are some of the things that cause oil spills. These can be prevented if you know the proper preventive measures on the maintenance of your vehicle. Through manual pinching of the valve cover, oil leakage is determined. Another way is to remove the gasket and putting the valve cover back into the cylinder head. When there is contact between the valve cover and the cylinder head, the cover should sit flat. In modern machinery, more sophisticated types of valves are being produced in answer to the growing demand of oil leakage in the upper part of the engine. Some are made from thermoplastic, sprayed with chrome, aluminum or carbon fiber. Chrome valve covers are famous in most street and performance cars of today. Just pick your choice but for sure, when you ask your friend what brand of valve cover he uses, he'd answer a valve cover from Roush.
