Timing belt replacement tends to be an expensive exercise that appears to make little difference to how a car runs, although failure of the timing belt can be a very expensive repair.
In an inerference type engine timing belt failure usually causes the pistons to collide with the inlet and exhaust valves, at the very least the valves will be bent and a technician will need to remove the engine cylinder head to replace them, in some cases, pistons can be holed, cylinder heads can be damaged and cam shafts can be broken.
To repair a severely damaged modern engine, the cost will be in excess of several thousand pounds and a full replacement engine may prove to be the most economical solution. Manufacturers recommend timing belt intervals but nearly all are different, your vehicle may not even have a timing belt as it may be a chain driven engine.
