Hey guys, thanks for responding so quickly.
The noise appears to be coming from the left hand side of the engine as you are looking at it from the front. It's more of a sharp metalic noise, almost like a static spark sort of sound.
Not sure i would be competent enough to try either of the suggestions you made myself so may have to go down the expensive route and take it into a garage to have it done.
Thanks again for your suggestions, its really appreciated
