Why is my engine making a ticking noise?

I recently purchased a used BMW and noticed that the engine is making a ticking noise. Should I be concerned and is there a way to fix this issue?

It is common for BMW engines to make ticking noises due to the hydraulic lifter system. However, if the noise is excessive or accompanied by any other strange sounds, it may indicate a more serious issue.

To fix this issue, you can try using a thicker oil or an oil additive designed for quieting engine noises. If the noise persists, it's best to take your car to a trusted mechanic for diagnosis.

Regular maintenance and oil changes can also help prevent these noises in the future. It's important to address any unusual sounds in your engine to avoid potential damage.
