Crank bolt torque for timing belt change (10v)

[Denis]

Absolutly right.
For the first torque shot i used a 1/2 drive , 3 feet bar and hit it with a
big piece of wood, say 4x4, 4 feet long,,,,,, yesssss it torqued. Ill go to
a garage to with the car (whenn i ll finish all stuff to make it run,)  it
with a high torque impact
