Failure Symptoms

A failing valve lifter may initially cause a slight decrease in engine performance or an audible ticking sound from the valve cover area. If left unaddressed, the lifter can cause uneven valve operation, leading to reduced fuel efficiency and increased emissions. Continued operation with a faulty lifter risks damage to the camshaft and cylinder head.

Installation Tip

Ensure the camshaft is properly lubricated before installing new lifters to prevent initial wear. Avoid overtightening the rocker arm adjustment, as this can damage the lifter or valve stem.

Service Note

Inspect camshaft lobes and rocker arms for wear when replacing valve lifters.
