How Does Your MINI Act When Its Timing Chain Is Going Bad?

Cam and crankshaft; are two crucial components of an engine. It is the camshaft's job to regulate the operation of the exhaust and inlet valves, while the crankshaft is responsible for converting linear motion to rotational motion and delivering it to the rest of the drive train.

Syncing the motion of these two shafts is crucial for smooth engine operation. And, it's the timing chain- that keeps these two shafts in sync. Now you can imagine how important a timing chain is. As you go through this blog post, you will learn a lot about the timing chain. So, please read this article till the very end.

A Brief Introduction to Timing Chain

The timing chain used in a car is similar to those found on bicycles and motorbikes—but much stronger. It is made up of an array of links connected to each other by means of metal pins. The timing chain of a car can easily last up to 150,000 to 200,000 miles.

Your car will battle all sorts of engine drama if its timing chain goes bad. This is why it is important to learn to recognize the warning signs of timing chain issues so that you can do something about it. Below is a discussion of all the common symptoms of a bad timing chain. Have a look…

Signs Your Timing Chain Is Going Out

Engine warning light is on

The engine warning light will come on if you have a bad timing chain. As you would have read previously, the timing chain is among the most crucial parts of your car's engine. It essentially keeps all of the engine components in sync and makes sure that the engine is working as a single unit. When this malfunctions, engine performance will be adversely affected—and a check engine light may appear. Long story short, if your car's check engine light is flashing, get its timing chain tested by a professional.

Hard time to start the engine

If your vehicle's timing chain is faulty, you may not be able to start its engine. Why is that, you asked? Well, the engine is designed in such a way that, if its cam and crankshaft are out of sync it will not start. And, as most of you probably know, the timing chain keeps these shafts in sync. So, obviously, if it goes bad, that synchronization would break; as a result of which you might not be able to start the engine.

Unusual engine noise

The appearance of rattling noise from the engine simply means some of its components are loose or damaged. If something is wrong with the timing chain, your car's engine will make a strange rattling sound. Not changing the motor oil on time can also result in the emergence of such a sound from the engine. Whatever the reason, if you find that your car's engine is making a loud rattling sound, ask a mechanic to check its timing chain.

Engine misfire

Engine misfire; you might not take it as a sign of a faulty timing chain. But, you should know that issues with the timing chain can result in an engine misfire in a car. Apart from this, an engine misfire in a car can be caused by many other issues like- a faulty spark plug, a clogged fuel injector, a problematic air intake unit, poor compression, and so on. If left unaddressed, it can result in expensive engine repairs that might cost you thousands of dollars.

Metal shavings in motor oil

Another common finding in a vehicle with a defective timing chain is the presence of an excess amount of metal shavings in the engine oil. That's why check the oil quality in your car from time to time, and if you find an excessive amount of metal shavings in it, have someone check on the condition of the timing chain. If the timing chain is fine and in good condition, it is likely that the engine bearing is damaged.

Wrapping Up

The timing chain is something that essentially keeps all moving parts of the engine in sync. So, if it fails, it will have a negative impact on the overall functioning of your car engine. Luckily, signs of timing chain failure are easy to detect. And, if you are coming across any of the above-said signs when driving your MINI, get its timing chain tested right away.
