D49.49.2.1 Bearings

    Start the engine and point the timing down toward the crankshaft. Listen for any heavy knock or clunk coming from the engine. If you have a rod or bearing knock, the timing light will flash twice for every knocking sound. If it flashes once for every knock, you have a valve train problem.

    The bearings help the shaft to spin freely inside the engine. When these bearing go bad, glaring signs will let you know they are bad or heading in that direction. One glaring sign is a noise that sounds like knocking. Faulty engine bearings need to be replaced as soon as they go bad.
