2000 Land Rover Freelander

Noises problem
2000 Land Rover Freelander 4 cyl Four Wheel Drive Manual 55000 miles

My freelander seems to make a fast knocking noise whenever the car gets to about 3.5 rpm and then stop again when it gets to about 4rpm, I was wondering if someone could help me figure out what it is as it gets very annoying when on the motorway at 70mph

Sounds like the vehicle may be getting too hot !
