What causes chevy silverado lifter noise?

A lifter noise is a common occurrence in v-8 engines, like the Chevy Silverado. This ticking noise is mostly caused by the valve lifters that get filled with oil. So, when Your engine is not running the oil can leak out of the lifter, causing the ticking. The lifter noise is not something dangerous for Your engine. This piece is designed with a drain hole that allows it to float or fall to the bottom depending the oil pressure. Removing carbon deposits by running an engine cleaner through the engine can help with the ticking noise. Replacing the lifters can be a complex process, that includes the removal of the engine heads. Only a trained mechanic should be performing this procedure.
