That is, if the crankshaft rotates one tooth, all the driven sprockets of the timing will advance the same.Some engines use VVT (variable valve timing) sprockets on the valve shafts. These have the ability to move the relative position itself with the teeth of its corresponding pinion. Guides Chain guides are necessary to prevent timing chains from vibrating, serving as a track to the timing chain. By addressing the positioning of the chains, they ensure the right arrangement of the chain along all of the engine components.Guides can either be fixed or tilting Timing chain The timing chain is considered the heart of the engine, as it connects the crankshaft to the camshaft, controlling the opening and closing of the engine’s valves so that these happen at exactly the right time to inject fuel and remove exhaust gases in a balanced way. Some chains, to help installation, maintenance or replacement operations, have signaling links that offer visual aid for the correct positioning. Tensioners A tensioner is provided in order to control the timing chain properly surrounding the crankshaft sprocket and the camshaft sprocket. Combined with a chain guide, tensioners ensure that the timing chain is kept under proper tension. This way they prevent the chain from vibrating and slipping off the sprockets. Symptoms Of a Bad Or Failing Timing Chain Engine Misfiring It is possible for the timing chain to stretch with time, and the chain skips a gear either on the camshaft or on the crankshaft. The engine’s timing will be out of calibration and you hear the classic misfire sound. Engine Light is Illuminated When the timing chain is stretched, it makes the engine perform poorly and so the engine emissions are increased. This triggers the engine light to come on. Rattling Noise When Idling Unusual sounds are a reliable warning sign that something is going wrong. when a timing chain is working its way loose, it causes vibration inside and this sounds like a rattling noise when the engine is idling. Engine Failure If the timing chain breaks as you are driving, the engine will stop and you will break down. If your car is parked up at your home and the chain is broken, the engine won’t be able to compress enough air to get it started.
