Best Practices

Using high-quality valve cover gaskets will reduce the chance of recurring leaks and additional repairs.

When replacing the valve cover gasket, we recommend having a valve adjustment performed, if applicable. Since the valve cover is removed to adjust the valves, this will save in labor costs.

Common Symptoms

Valve cover gaskets need to be replaced when they begin to leak oil. They can damage other GMC Rally Wagon 2500 engine components, especially belts and hoses.

Oil leaking from valve cover gaskets can result in a burning smell coming from under the hood.

Common Misdiagnoses

Components such as spark plug tube seals and grommets can also leak oil, which can be mistaken for a leaking valve cover gasket. The seals and the valve cover gasket should always be replaced together.
