My emergency break was stuck, so we put it on the rack at work and fixed it. while up there I looked under the engine to check the power steering belt, it squeaks when its cold. Well the bolts that hold the front engine mount to the frame, well used to be frame, are not holding anything. The frame is so rusted there is a 2 inch gap where the motor sags, and you can bounce th motor by gently pulling on the mount. Is it fixable or would it be too expensive? Kbb is about 6-900.
