Maintaining a vehicle is a car-owner’s responsibility. It is important to understand what types of issues your specific vehicle may have and know where to go when those problems arise. If you own a Jaguar, you may have an issue with its timing chain. We’ve put together some signs, symptoms, and tools to learn more about Jaguar timing chain problems and what you can do to get it fixed.

The Importance of a Timing Chain

A timing chain (also known as a timing belt) is an important aspect of a vehicle that ensures that the car runs smoothly. Located inside the engine, the rotation between the crankshaft and camshaft opens and closes the engine’s valves. When the timing chain stops working and becomes defective, it can cause internal damage to the engine.

The Defect

If you purchased a Jaguar between 2012-2014, it is very possible that you have a defective timing belt. Jaguar Land Rover had designed its vehicles at that period with cast aluminum tensioning rails that were supposed to reduce tension in the timing chain. Unfortunately, there has been evidence provided that shows these rails are defective and can cause severe damage to the vehicle.

Signs of a Defective Timing Chain

Listed below are several warning signs of timing chain issues:

Oil Leak

Motor oil can leak from the timing chain’s cover if the gasket wears out, is cracked, or was not properly installed. Leakage from the timing chain often time results in the engine overheating and premature wear and tear on the timing chain.

Engine Ignition Failure

If the timing chain is defective, it can cause the engine to not ignite or turn over. When you start your vehicle, you’ll be able to hear the starter motor engage, but because the timing chain is damaged, it will not turn over completely. The timing chain can also break while the engine is running, which can damage hardware to the cylinder head. This includes the valves as well as the crank bearings and oil pump.

Engine Misfires

Because the timing chain is attached to pulleys associated with the crankshaft and camshaft, a defective timing chain can affect the engine’s fire rate. A misfire happens when the chain slides on the camshaft drive and causes the cylinder to prematurely close earlier than it should. This misfire can cause severe damage to the engine.

Ticking Noise

When a timing chain is worn out or defective, it may begin to make a ticking sound. The timing chain is attached to various pulleys to the crankshaft and camshaft. The sound is caused by a vibration located inside the motor that you hear when the engine is idle, as the chain is loose. This can also be an indicator of low oil pressure or lack of lubrication within the engine.

Metal Shavings in Oil

If you have noticed metal shavings in your oil, this is another indication that something is wrong with your Jaguar’s timing chain. Metal shavings will appear due to the separation of oil as it heats up and becomes exposed to chemicals found in gasoline. When the timing chain begins to wear out or is defective, small pieces of metal can come off the chain and end up in the oil pan.
