What happens when a Cambelt fails?
When the timing belt breaks, the crankshaft will continue to spin at 1000 rotations per minute, while the camshaft will stop turning. As a result, the pistons will continue to rise and fall in their cylinders, but they will strike closed valves.
How do I know if my Cambelt needs changing?
Visual Check. Another way to check whether your cambelt needs replacing, is to take a look at the belt itself. If it is becoming worn, the belt will appear to look glazed or glossy on the underside. This means the rubber is getting hard and will not provide the flexibility the belt needs.
