Ok so basically I've got a 1995 Vti-R and something I've noticed since I bought it is that when you hit about 3100RPM and up through the rev range you can hear a feint sort of buzzing/rattling sound coming from the engine/gearbox area, this sound seems to be less audible when the car isn't moving and in this case can only really be heard when the revs come back down sometimes, even while the clutch is pressed.

It sounds like it's coming from the passengers side of the engine bay. The strange thing is you can only hear it from inside the cabin...? My engine is running good and hasn't got any problems so I don't think it's anything serious, it's just annoying and I'd like to get rid of it.

So, anyone got any ideas or has anyone else experienced this?
