Why is my Ford S-Max's engine making strange noises?

I recently purchased a new Ford S-Max and I have noticed that the engine is making some unusual sounds. They are not necessarily loud, but they are definitely different from other cars I have owned. Is this something I should be worried about?

It is common for new cars to make some unusual noises during the break-in period. However, it is always better to be safe than sorry when it comes to your car's engine. It would be a good idea to bring it in to a licensed Ford mechanic for an inspection just to be sure.

It could be a problem with the timing chain or a faulty valve. These are known issues with the Ford S-Max and should be addressed by a professional as soon as possible. Don't wait until it becomes a bigger and more expensive problem to fix.
