    Q:
    How can a noisy Lash Adjuster be identified during engine idling for the 1992 Chevrolet Beretta? Posted by Verified Customer
    A:
    A noisy valve lifter can be identified during idling by using a length of hose placed near each valve and listening at the hose's other end. Alternatively, you can remove the rocker arm cover and place a finger on each valve spring retainer, one at a time, while the engine idles. If a defective lifter is present, the shock felt as the valve seats will reveal it. This noise is often caused by trapped dirt inside the lifter.

    Q:
    How can a noisy Lash Adjuster be isolated for the 1990 Pontiac Grand Prix? Posted by Mamie H.
    A:
    A noisy valve lifter can be isolated while the engine is idling by using a mechanic's stethoscope or a length of hose near each valve location, listening at the other end. Alternatively, you can remove the valve cover and touch each valve spring retainer one at a time to feel for shock if a lifter is defective.
