am in the middle of an engine transplant and found the engine mounts were pants and needing to be changed, took the passenger side off, it was mega tight but using brute force, pshycology, a scaffold bar and a frickin enormous hammer is gave in, now, the drivers side seems to be tough as a tough mans nuts can be,
I have tried :
tons of wd40
the old hot water/cold water technique
the tightening it up to undo it (it didnt move)
heating it till it glows
a torque wrench
4x 14mm sockets (now all perfectly round)
3x nut gouges (as above)
a 6 bar air wrench
an 8 bar impact gun
have burnt out 1 compressor
bent 2 extendable bars
bent 2 knuckle bars
broken a drimmel
cutting it out from above with a resipro saw
so, the nut is now round, so using a nut splitter and the resipro have cut 1/4 out of it and bashed frick out of it with a hammer and it still will not move!!
and before any one says yes i am turning it anti-clockwise
any ideas anyone????
