Why is my BMW 8 Series engine making a loud clicking noise?

I recently noticed that my BMW 8 Series engine is making a loud clicking noise, especially when I start the car. What could be causing this and how can I fix it?

This could be due to low oil levels or worn out camshaft bearings. It's important to check your oil levels regularly and have them topped up if needed. If the issue persists, it's best to take your car to a mechanic for further inspection.

It's possible that the clicking noise is coming from worn out lifters or valves. This is a common issue in older BMW 8 Series models. I would recommend having a professional mechanic take a look and replace the worn out parts.

Another potential cause could be a loose or damaged belt. Check the condition of your engine belts and tighten or replace them as needed. If the noise continues, it's best to have a mechanic inspect it to prevent any further damage.
