Morning all, quick question. I returned from a long drive today and noticed that the right hand bolt holding the fan enclosure onto the engine had shaken loose (probably due to investigations by garage of petrol smells last week). The bolt and washer remained in place on top of the enclosure however I wonder if I have lost a spacer from under the unit? There was an almighty bang as I was driving along that I put down to running over a stone but I'm wondering if it was a lump of metal dropping off the engine.
