What is a Timing Chain and where is it Found?

The timing chain can also be called the timing belt. It is found at the front of your Mini, inside the engine. It has been an essential part of all combustion engines since the earliest days of motoring. The timing chain is connected by a series of gears and pulleys to the camshaft at one end and the crankshaft at the other. In order to start your Mini successfully, the timing chain has to be able to rotate without any hesitation.

At its core, the timing chain is simply an advanced rendition of a bike chain, as it uses links that move on toothed sprockets to operate. The sprockets are able to open and close cylinder head valves, that allow for the pistons and their connecting rods to move inside the combustion chamber, allowing the combustion cycle to occur.

Signs and Symptoms of Timing Chain Faults

The symptoms listed below are some of the most common timing chain issues that Mini drivers experience. When these occur, they shouldn’t be ignored and should be investigated by a qualified mechanic.

There are so many reasons as to why your engine may misfire that it can be easy to overlook the timing chain. This is why it is essential that if you notice misfires becoming a frequent part of your driving experience, you seek diagnostic work as soon as possible to discover the root cause. Misfires caused by a timing chain are known as mechanical misfires and happen when the timing chain skips a gear. This causes the engine’s delicate calibration to become misaligned, which is what causes the misfire.

This almost always points to timing chain faults that are either caused by part wear or poor lubrication. When the timing chain becomes worn or dry, metal shavings will chip off its surface, which will be captured by your oil and travel through the engine system. However, if you’ve ruled out your timing chain, then it is worth noting that metal shavings can also be caused by cylinder head wear.

Engine Noise

Engine noises such as rattling or clunking should never be ignored as they almost always point to a serious engine issue. This is caused by a loose timing chain that is able to vibrate or rattle when the engine revs or ticks over. A loose timing chain is far more prone to sudden failure, so should be remedied ASAP.

Act Fast!
