How to fix a leaky valve on a Ford S-Max?

I have noticed that my Ford S-Max has a leaky valve. It's causing a small but constant drip of oil. What could be causing this issue and how can I fix it?

It's likely that the valve is worn out and needs to be replaced. It's a simple job that can be done at home with the right tools. First, locate the valve and remove it. Then, clean the area and apply a sealant before installing the new valve. Make sure to tighten it properly and check for any leaks.

Another reason for a leaky valve could be debris or dirt build-up. Try cleaning the valve and surrounding area thoroughly and see if that solves the issue. If not, it might be best to take it to a professional for further inspection.
