Noisy Engine? This Mechanic Reveals the Common Culprit

Noisy Car Engine? It Might Be Your Timing Chain. Car owners often experience the unsettling sound of a noisy engine. Talleres Ebenezer, a mechanic from Seville, Spain, recently posted a video explaining a common cause: a faulty timing chain tensioner. In the video, Ebenezer uses a disassembled engine to show how a lack of oil pressure in the tensioner can cause the chain to become loose, resulting in a rattling sound, particularly noticeable when starting the engine. He emphasizes the importance of regular maintenance and the use of quality parts. "The tensioner pushes against a 'patín' (slide) to keep the chain tight," explains Ebenezer. "If the tensioner loses pressure, the chain slackens, causing noise." He also warns against the use of low-quality chains, which are more prone to stretching. The video has gained significant traction, highlighting the relevance of this common car problem. Regular maintenance checks can help prevent such issues, saving car owners from costly repairs.
