2002 - 2006 Toyota Rav-4 valve Cover Fits: Toyota Rav4(2.4 LTR) Years: 2002 • 2003 • 2004 • 2005 • 2006The valve cover is a aluminum cover that is found on very top of the engine. The valve cover is attached to the engine by a gasket made of rubber or cork. The valve cover and gasket seal the top of the engine and prevent oil leaks. These covers are removable so the mechanic can access the valves for adjustment. Because of the high temperature of the engine, it is common for the valve cover gasket to get brittle and break. If the gasket is worn out, it will leak engine oil and the top of the engine will be covered in oil. Since the engine is losing oil, running the car for too long without an inspection and repair can cause engine damage.Get this valve cover for the lowest price on the market, enjoy our FREE SHIPPING and receive it at your doorstep as soon as tomorrow.
