hey all,my car(the purple hobit) has developed a strange rattle, i say rattle it's like a transit or black cab engine noise only not quite as loud, it happens when the engine is cold or warm!i hear it when stationary but cant hear it when driving though, this may be because of the road noise!? it's got 58k on the clock, r reg, cant think of what it is, wouldn't of thought it would be the chains with that kind of millage on the car, also wouldn't have thought it would sound like a black cab(only quieter!) if it was the chains! but i'm a novice hence asking for help, also got an m.o.t in a couple of weeks(perfect timing hey grr) so all help/ideas/advice welcome, cheers all.....
