so majority of the work is now done :thumbup1:
just got a few hoses and electrics to refit then its nearly happy days.

ok so i have now got my cylinder head in place and i have been given torque settings and procedures these being

stage 1 tighten to 25Nm
stage 2 tighten to 49Nm
stage 3 turn another 90degrees

however i have heard other stories from others now so i am a little confused
i have been told that once torqyed to stage 2 i then UNDO all bolts in reverse order and then redo as in stage 1 and 2 and then comes the 90degree turn.

unfortunately i arent a mechanic so i arent 100% sure what to do :crying:
