The Mini Cooper is a part of pop culture. Its distinctive design makes it highly recognizable. It is dependable and fun to drive. However, as with every other vehicle on the road, it can experience component failures. Mini Coopers are notorious for timing chain failure, but the issue does not affect every model.

If you own a Mini Cooper, you could face timing chain failure. The issue affects Mini Coopers manufactured between 2007 and 2010 that have the Prince engine. Fortunately, if you own one with the Prince engine, you can help to prevent the problem from happening.

When the timing chain begins to fail, it often creates a rattling noise. This noise is often noticeable when idling, driving slowly, or in cold temperatures. If you are experiencing the dreaded rattling noise, it is very important you have it looked at immediately. You do not want the timing chain to break and permanently damage the engine.

Symptoms of Timing Chain Failure

The timing chain is a vital component that turns the cam and crankshaft. When it begins to fail, the components will not work together properly. Your Mini Cooper must have the chain to operate. When it begins to fail, you may experience some obvious symptoms.

• Dreaded Rattling Noise: The rattling noise is referred to as the “death rattle.” It is produced when the timing chain is loose. It often happens when the plastic support rail breaks or becomes weak. The support rail then will not be able to create the tension needed for the timing chain. This, in turn, produces a rattling noise as the engine idles.

If you hear a rattling noise in your Mini Cooper, have it inspected right away. Any type of rattle is an indication that something is loose. You will want to get it fixed before it breaks.

• Misfires: As the timing chain ages, it can stretch out of shape. This can cause it to skip a gear resulting in a misfire. You may also notice that the engine runs poorly and it does not accelerate like it used to.
• Car will Not Start or Dies: If the chain has already failed, your Mini will not be able to start. If it fails while you are driving, it can cause extensive damage and your engine can stop.
• Metal Shavings in the Oil: It is important to have your oil changed regularly. Over time, the oil in your Mini Cooper will break down and become contaminated. This can damage your engine components. If the contamination is metal shavings, it could be due to a damaged timing chain. When the timing chain starts to fail, metal shards can fall off and contaminate the oil. Having your oil changed regularly gives your mechanic the opportunity to find these shavings.
• Illuminated Check Engine Light: The check engine light can be triggered by many different issues. When your Mini’s light comes on, the computer has detected a problem. This will produce a trouble code. Our expert mechanics can run a diagnostic scan to determine the exact cause of the issue.

Preventing Timing Chain Failure

Timing chain failure can be prevented or delayed. With proper maintenance and lubrication, the life of the chain can often be extended. Keeping current on your oil changes will also help prevent timing chain failure. If you have a Mini Cooper with a Prince engine, we recommend that you have your oil changed every 6 months or 5,000 miles.

Staying current on oil changes can help to prevent failure. However, there is still a possibility you will experience the dreaded “death rattle.” If you hear a rattling, have it diagnosed and repaired right away.
