I've had a problem with the 147 recently, it's been making a really annoying whining noise which is coming from the belt side of the engine.
It increases with engine speed and sounds to me like a duff bearing. I removed the auxillary belt today and started the car, noise stopped, so I know it's one of the components running off the aux belt. I spun each component manually and the alternator, PS pump, and aircon compressor all seemed very smooth with no noise and no noticeable play in the bearings. The fixed tensioner and the adjustable tensioner both seemed to spin quite a lot and make a little noise + some slight movement in the bearings too.
I tried greasing/oiling both up quite a lot but it doesn't seem to have affected the noise much (if at all). I'm probably going to swap both along with the belt whilst I'm at it, the only things I wanted to know was :-
1, Is there anything I'm missing that could be causing the problem. I don't know much about aircon compressors but the noise seems more to the rear of the engine instead of the front so I'm ruling that out. Also I'm assuming that clutch release bearing would be noisy even with the belt removed so I've ruled that out too (as well as it being on the other side of the engine). Any thoughts would be helpful.
2, I can't get parts till new year (I think) so is this likely to cause any damage if I drive it. I can't see how it would, although I'm aware it would strand me if the tensioner broke or seized completely. The main belts have been done not too long back and appear to be in good shape (no signs of rubbing or anything) and all guards/covers are in place. Again any advice would be appreciated.
Thanks in advance
