Engine Valve Cover (Rocker arm covers, valve cover,engine valve cover kit,cylinder cover)

What They Do
The valve cover, as you might expect, covers your valves. The intake and exhaust valves that allow air into and exhaust out of the engine cylinders, along with the various timing parts that move them need to stay lubricated to function properly. The valve cover does the important job of keeping the oil contained, and keeping dirt and debris out of the oil.?

How do I Know if Valve Cover Needs to be Replaced?
If the valve cover on your car or truck is cracked or warped, you¡¯ll want to replace it as soon as possible. Your valvetrain can be damaged by inadequate lubrication and by exposure to dirt and debris.?
