I have just noticed a funny noise on my 300zx 1990
it sound like a clock, clock clock (or a horse walking) and it seems to be coming form the drivers side and when you open the door and you have the air pipe that join the door, it seems to be coming form with in there ( tube). nothing was on (eg air con) and you cant here it from under the bonnet
it only happens when the engine is on, but it sounds like something bubbling
