[Vwdiesel] Rod bolt replacement?

[slatersfb at aol.com]

Do not replace connecting rod bolts; in a previous thread, this was the general concensus; my choice also. 
What vehicle is this engine in?
Will you replace main bearings also?

The Bentley says 22 ft lbs +90° for the torque on rod bolts.  Do the bolts 
need to be replaced each time?  Should they be?  I couldn't find anywhere that 
said they should be, but I couldn't find that regarding head bolts either, and 
I know those should always be replaced.
