Hey, I'm new to the forum so apologies in advance if I'm on the wrong bit...
I've got an 04 st170 with 90k on clock, fsh and timing belts been done bout 2k ago so engine is quite sound apart from the loud kinda rattling, vibrating noise coming from the right hand side of the engine.. This only started yesterday but has got louder today.. When I've had a listen under the bonnet it sounds like its coming from the area done near the drive belt so was wondering if it might be something like the bearings in the pulleys but I'm unsure.. so if any1 could help or knows of any common issues it would be much appreciated
