Good point John,

"Torque to stretch" type bolts must be replaced or they will fail if
torqued a second time, but VW has used both types, identified by the
length of the tread (stretch = 22 mm, std = 10mm).  I would replace the
stretch type with standard bolts if possible.  Obviously both are dealer
items and I am sure several $$$$ each times 8.  By the time you replace
these and the case studs  you are in it $20O-$300 before even getting
into the other major parts and machine shop work.

Also, the Haynes manual states that the flywheel/drive plate bolts must
also be replaced.

Again, you get what you pay for, and a top quality rebuild will cost
$3000 to $6000! (Robert Lilly spent the high amount on his 2.1)
