"Engine mounts are SHOT. At certain RPM's, i can visibly see my hood shaking tremendously. The whole car rocks side to side. I think i have an engine shock as well on the drivers side, no? If so, it is shot as well. I plan on replacing them ASAP just need to figure out how. I've done engine mounts on my E63 AMG so i doubt this car will be too much of an issue"

Ok, I would recommend getting Lemfoerder mounts. The job is not too difficult. There are some clearance issues with getting access, but you will find a way.

The fuel leaks can cause the performance issues you mentioned. The engine will be sucking in air where it needs diesel and while it may not cause damage, it won't help your performance.

The engine shocks are a luxury item. They buffer the vibrations of the engine while it is shutting down. They won't cause any issues while driving the car.
