Few items in your Plymouth have the same degree of possibility possessed by the Plymouth timing belt/timing chain to cause expensive engine damage when they break. In certain engine configurations, if the Plymouth timing belt/timing chain breaks, it could cause damage to the valves and other components of the engine, so it should definitely be checked at the regular intervals listed in the owner's manual, usually at sixty thousand miles and again at one hundred thousand miles, though replacing is really better than merely checking. This part links the crankshaft to the camshaft, and when it is operating correctly, provides efficient operation of the exhaust and intake valves. As the Plymouth timing belt/timing chain begins to wear, however, the operation of the valves can become sloppy, causing improper air to fuel ratios, excessive emissions, a rough idle, and increased engine noise. Sometimes a worn Plymouth timing belt/timing chain can be easily diagnosed without disassembling anything, by a loud chattering noise coming from underneath the timing cover. More often than not however, you will not notice a problem until it breaks or a visual inspection is performed. To prevent premature wear when replacing the Plymouth timing belt/timing chain, it is always a good idea to replace the array of gears and pulleys that complete the timing system at the same time.
