Hi, no they will only make a noise when they have spat out all the oil and shredded the bonded rubber mount, my only clue was the rocking of the engine when revved and as mine is manual the worn gearbox mounting made it hard to engage first and second the other sign was the gearstick was moving excessively when accelerating or decelerating so I just changed all three as they wear as a set fortunately the gearbox mount is solid rubber and not that hard to change but the engine mounts are, one had started to lose oil and both sides the rubber was creased and beginning to split.
Steve.
