Installation and maintenance

Technicians should perform regular inspections of the valvetrain, specifically checking for abnormal ticking or knocking noises that might indicate wear. When replacing components, it is vital to verify that all pivot points are correctly seated and that the valve lash is adjusted to manufacturer specifications to prevent premature wear of the rocker assembly.
