On this V8 engine, timing chain problems are very common. Because the timing chain tensioners were made from plastic, they can fail prematurely and cause serious engine damage. A noticeable engine noise while idling or during a cold start can indicate a timing chain tensioner problem. The engine noise may also be accompanied by a rough or uneven engine idle. Improved components are available to remedy this problem.
