engine vibration

Engine

Vehicle Information: Model(924/944): 944; Year: 1984; Engine (type, size, modifications): 2.5 liter n/a; Total Mileage: 165,000;

there is a vibration in the engine at idle and through all the gears except it settles down quite a bit in 5th. the engine has no noise in it except for a low whine and is responsive throughout all ranges. i just bought the car and have put maybe 1000 miles on it and have noticed no change in severity. a mechanic suggested motor mounts. another said maybe timing or balance belt. neither were porsche mechanics. i suspect motor mounts as it is a stedy even vibration and if you full power it, it is no worse maybe less vibration feel to it. thanks, Dale
