Why is my Ford Transit Custom engine making a loud knocking noise?

I recently noticed that my Ford Transit Custom's engine has been making a loud knocking noise while driving. It's been happening for a few days now and I'm getting worried about the health of my car. What could be causing this and what should I do to fix it?

Hi Emma, the loud knocking noise from your Ford Transit Custom's engine could be caused by a number of reasons. It could be due to low oil pressure, worn out engine bearings, or a faulty fuel injector. I would recommend taking your car to a mechanic to have it checked as soon as possible to avoid any further damage.

Hey Emma, I had a similar issue with my Ford Transit Custom and it turned out to be a faulty water pump. Water pumps are known to make a knocking sound when they start to fail. I suggest getting your water pump checked by a mechanic and replaced if necessary.
