The hydraulic lash adjuster sits between the cam and the valve and takes up clearance automatically. When one starts to fail you get a tick that is loudest on a cold start and often quietens as oil pressure comes up, and on the Pentastar family a noisy adjuster is worth investigating early rather than living with. Quantity required depends on the engine, so count what you need before ordering.
