Why is my Ford Mondeo's engine making a ticking sound?

I have a Ford Mondeo and recently noticed a ticking sound coming from the engine. It seems to get louder when I accelerate. What could be causing this and how can I fix it?

The ticking sound could be due to low levels of oil in your engine. Check the oil levels and top up if needed. If that doesn't fix the issue, it could be a problem with the valves or tappets. It's best to have a professional mechanic take a look at it.

Another potential cause of the ticking sound could be a cracked exhaust manifold. This is a common issue with Ford Mondeo engines. It's important to have this fixed as soon as possible to prevent further damage.

It's also possible that the ticking sound is caused by a faulty timing belt tensioner. This can cause the engine to make abnormal noises. It's recommended to have the timing belt and tensioner replaced every 60,000 miles to prevent this issue.
