There is liquid in the mount? I thought these cars used some sort of rubber? Now that you say this I have felt more engine vibrations in the steering wheel and gas. I fell it more if there are parts of the road that make the whole car go up and down or if I turn to hard. I've felt and heard of this at about the same time as I've noticed the black water like fluid.

From the looks of things I've ran a towel down under and all around trying to find a sorce back to the oil of the engine, but there is nothing. It's just right there at the motor mount. From the looks of things it must be leaking because there is some rust or old junk running down the side all along this thing a dripping down onto the ground.

How much does something like this going to set me back?
