Why is my Ford Galaxy's engine making a strange rattling noise?

I recently noticed a strange rattling noise coming from my Ford Galaxy's engine. It seems to happen when I accelerate and gets louder as I increase speed. What could be causing this and is it something I should be concerned about?

This could be caused by a number of issues such as loose belts or valves, worn out bearings, or air in the oil. It's best to have a professional mechanic inspect your car to accurately diagnose and fix the issue. Better safe than sorry!

I experienced the same issue with my Ford Galaxy and it turned out to be a faulty timing chain tensioner. Don't ignore this noise as it could potentially cause serious damage to your engine if left untreated.

I've had this problem before and it was due to a loose exhaust heat shield. Easy fix, just get it tightened or replaced if necessary.
