Rattle when going over bump (engine mount) can feel it in pedals

[da20valve]

Whenever I go over bumps on my SP20 there is like a rattle ( sounds like something is lose ), I can feel it under the pedals, any idea's ??, also what's the easiest way to see if I need to change the engine mounts in my car, do I just visually inspect them ??, or do you have to take them out to before you can tell if they're stuffed.
