motor sitting down on cross member. Passenger side motor mount bottomed out. Tried for an hour to loosen engine side motor mount bolts. 2 ft pipe on breaker bar and still no break. Afraid to snap off, then it's a whole new game. Center bushing well worn, but I just installed new bolt and good enough for now. Any suggestions how to loosen these bolts. Are they installed with some gorilla type threadlocker, or what?:-{}
