Question

Accepted Answer

Setting and particularly re-timing of the timing system is a delicate process which might lead to rather severe damages of the car engine if something goes wrong, therefore this kind of repair should be attempted only by persons with fairly vast experience in such cases; as for the rest, it is highly recommendable to consult an expert. Firstly, pull the cable off the negative terminal of the battery as well as the spark plugs. Then you need to turn the valve cover, and then to pull it off, next, you need to drain the engine oil, and then the drivebelt and its tensioner, and at last the engine front cover must be removed. Turn the engine clockwise until the No. 1 piston is at the top of the exhaust stroke; align the keyway and markings on the camshaft sprockets. While turning your camshaft removed the timing chain tensioner, and the upper timing chain guide with the help of the exhaust camshaft sprocket bolt. Go forth and, eradicating the adjustable and fixed timing chain guides and then the intake camshaft sprocket bolt. Upon departure of the timing chain, do not rotate either of the camshafts or the crankshaft to prevent damaging the engine. , clean and check the condition of the chain tensioner, timing chain guides and sprockets and replace any that look suspicious. As described above, it is recommended that the experience driver should turn the crankshaft with his hand before starting the engine to feel some specific level of resistance to access the presence of some problems. Upon fitting of the timing chain, ensure that the given timing mark on the crank sprocket is in line and slot the intake camshaft sprocket and bolt it using a new bolt and tighten loosely. Place the timing chain in correct relative position of the colored links to the camshaft sprockets, then bolt in the adjustable and fixed timing chain tensioners, also the upper timing chain cover. The camshaft bolts should be tightly fastened with the camshafts held from turning which will provide enough looseness for installing the timing chain tensioner, which is in compressed position, and making sure that the tensioner assembly in well set. Replace the timing chain oiling nozzle and covering provide sealant on the access plug and replace the valvecove and engine front cover. Reverse all the steps you employed when carrying out the removal process, replace the oil filter, refill the crankcase with oil, reconnect the battery and start the engine and check for oil leaks.
