Excessive vibration

[audifan]

Aux belt it for the climate compressor and the alternator driven of the crankshaft. Cam belt joins the crankshaft, water pump and valve gear. Both have idlers / tensioners.

Always good to check things out as soon as possible, but losing the aux belt not catastrophic, just no charging of the battery and no air conditioning.

Quick update - aux belt removed and checked but all is well, its a dayco in excellent condition and had been put back perfectly after the recent work. Noise is definitely from right side of engine block so almost certainly not belt or pulley related (clutch, gear box?). It’s not got any worse, so leaving it for now unless things get significantly worse. Will update this thread if and when I get to the bottom of the issue.
