Do this test.. open the bonnet, get a mate to watch the front engine mount while your sitting in the car, with the engine running, handbrake firmly applied, get the car "rocking" by bringing the clutch up to the biting point over, and over again.. I f your mate says it looks like the engine is trying to leap out, then you probably need a new front engine mounting

If your worried about the clutch biting point bit, have a practice before you use your mate!
