I finally got the Harmonic balancer bolt undone, I had to get 2 M12x60 fine bolts to wack in the other end of the crank to stop it turning with a crowbar between them, and a few taps with the copper hammer on the breaker bar socket (righthand thread) it came undone easy as, then I could get at the tensioners for the cam belt, one was easy the other is a bit asian in design, I had to grind the outer edge of 17mm socket so it would fit in the hole that the bolt is in, to make it worse FIST had fcuked with it as well, but it succumbed to the might of me in the end. lol
