Just got back from a 3000Ks round trip with the caravan and since back noticed a grinding noise coming I think from the clutch but only at take of louder in reverse, once engaged good as gold. There is no slippage. No noise when depressing clutch when idling. Mounts look good. Would the belt tensioner be the culprit as when the weather is moist for a while now I have been getting a noise for the first 5Ks or so (Any other old car I would say it was a slipping fan belt). Any help would be greatly appreciated thanks.
