Crank bolt torque for timing belt change (10v)

[bob.rossato at att.net]

If you're using the 2079 extension (I get the impression you have one since 
you knew the center-to-center length) then it doesn't matter what the length 
of your torque wrench is.  Just apply 258 lb-ft of torque with the 2079 in 
line.  If you are looking to do it without the 2079, then the torque value is 
330 lb-ft, at least that's the approximate number I remember from my Bentley.
