I'm not sure about 6cyl mounts but over the years the rubber insulators in them are probably shot. I break the rubber in my trans mount about once a year and the back tires start to hop on take off. My brother's car engine fan hit the radiator (or the other way around) when someone backed into the front of his car, it didn't bend the bumper or hurt anything else major, but temporarily pushed the radiator back into the fan. One solution would be to use a shorter fan spacer, but definitly replace mounts. The clutch on a v8 pivots between frame and block letting the engine go through its motions and only change the clutch geometry slightly. You might have something binding and keeping it from moving freely, check clearances and other pivot points. I am basing this advise on a v8 though, I've never really looked at a 6cyl from a mechnical point of view.
