So today I had the engine rattle sorted, to cut a long story short, I've driven between 3-7 miles since I got the car back from the accident repair centre, as the sound has been alarmingly bad.
I've driven the car home which was 2.5 miles, and then to the Ford garage to have the rattle investigated and repaired. I only managed a couple of miles when the belt let go, and I lost the power steering.
It's a poor quality picture, but this was the lower roller, or what was left.
Plus as you can hear, it's much quieter
