Yesterday in the 63GT, I turned at light and goosed it a bit due to oncoming traffic. Heard the fan blade kissing the shroud, and simultaneously felt a shift in the gas pedal pressure. Don't even need to look at it, been down this road many times. Due to torque under acceleration, the motor tries to lift on the left side, eventually the vulcanized rubber in the left motor mount lets go, and the motor lifts. The right side mount is never a problem, since the motor pushes down on that side, while lifting on the left side.
The fix is easy, a small linked chain bolted to the top mount stud, and ran to a frame mound bolt just below. I leave a bit of slack so the motor will not vibrate as if in a solid mount. But when the motor begins to lift, the chain tightens and holds it in place. I have left the chain in place on the 62GT for decades, and cannot believe I did not install a chain in this car when I first got it, about 30,000 miles ago.
