Valve Cover Gasket

How To Tell It Needs Replacement
Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you may not be aware of. The valve cover is an extremely common place for this to happen. Years of exposure to extreme temperature change degrades the gaskets and causes failure. Replace yours to keep your engine oil in your vehicle. Trouble trying to track down your leak? The easiest way to do so is by cleaning your engine, then examining for leaks.
