Cheers lads, Barry's place isn't too far from me actually, i'm in Law.
Boab, cheers m8 but no need. It sounds like a knackered bearing from the cambelt area. I don't think its the alternator and i'm hoping its the alternator belt tensioner. I'll take the belt off tomorrow and see if the rumble is still there. If it is it may be the cambelt tensioner
