I've had my starlet for a good 7-8 months now and Its had this noise as long as I remember, when I start it up there's a sort of rattling noise but it used to go after It'd had been warmed up. A friend of mine identified the problem as the crankshaft pulley, it appears to wobble side to side and that's supposedly what causes the noise, and up until recently it's been fine but now it constantly rattles, hot or cold and I can hear it when I'm driving where as I couldn't before. Any ideas as to whether it is in fact the pulley and if so how I can fix the problem? Thanks in advance Sam
