The Isuzu XL-7 may be one of the most affordable SUVs of its time, but the automaker did not cut corners when it comes to making this reliable family vehicle. So it can be surprising for many XL-7 owners when its timing chain get worn out faster than normal.
The timing chain of the Isuzu XL-7 is expected to wear out over time, but if it wears out too fast or too soon, it is a cause for concern. So once the timing chain stretches out prematurely, you need to have it and its supporting components checked as soon as possible.
The XL-7 SUV\'s timing chain needs to be at a specific tension in order to work properly. This constant exposure to tension will cause the metal links to gradually expand at a slow rate. This \"stretching\" process is normal, and auto manufacturers have anticipated this and have integrated special tensioners that automatically adjust the tension of the timing chain so that it remains taut despite being stretched. But despite this, the chain will eventually become too slack for the tensioner to fix and must be replaced.
Timing chains usually need to be replaced between 40,000 and 100,000 miles, depending on the vehicle. The replacement interval can be slightly shorter if the SUV is used frequently for towing and heavy duty applications. However, timing chains can stretch and wear out faster than expected due to three factors:
The timing chain tensioner is operated via pressure from the motor oil circulating in the engine. When the engine starts, oil pressure builds up and pushes the guide of the tensioner against the timing chain and removes the slack. And once the engine is switched off, the oil pressure goes down, the tensioner loosens, and the chain goes slack again. However, if the oil has expired or it is too low, it will no longer produce enough pressure needed for the tensioner to push against the timing chain properly. This may cause the timing chain to jerk up due to the added slack, resulting in added wear. If the slack is so severe, the chain guides may even break due to the force of the jerk.
Oil can also cause the timing chain to get damaged prematurely if it isn\'t changed often than normal. Engine oil changes are supposed to be at intervals of significant distance; if it is done far too often, the fluctuations in pressure caused by draining and refilling the engine of oil will bring additional strain to the chain.
In some cases, the timing chain tensioner may also cause the timing chain to stretch out faster than normal. A tensioner that is too loose, for instance, may not be able to put enough force on the chain, causing it to jerk. On the other hand, a tensioner that\'s tightened too much may move slowly or even lock up, damaging the chain as a result. Tightening the tensioner to its recommended torque can fix this problem, but if it is already too damaged, worn, or defective, it must be replaced immediately.
