have never heard of a problem with the reuse of flywheel bolts.i myself have worked in the states and israel and have worked on myriad types of vehicals and such a question has never come to mind.nor have i seen such a reccomendation in a manual.one time a flywheel bolt broke upon insertion with a ir impact wrench.that was easily removed and a new one inserted. --- On Sat, 9/12/09, Jeff Greenfield <[email protected]> wrote:

No problem re-using the Flywheel Bolts. However, they and the holes in the crankshaft need to be cleaned of the old Loc-Tite and any oil/grease. DO NOT use taps and dies unless to clean bolts snd holes unless the threads are damaged. There is something called a thread chaser which is much better suited for this purpose as a thread chaser will clean the threads without removing any metal which a tap/die will. Here is one such rethreading set, I'm sure the same thing is available from other sources for less. http://buy1.snapon.com/catalog/item.asp?item_ID=56049&group_ID=1148 When re-installing the flywheel, use Red Loc-Tite on the bolts and torque to spec. DO NOT use anti-seize here as you do not want the flywheel to come loose (I've seen it happen and it's not pretty). Lastly, if replacing the clutch, the 'right way' is to resurface the flywheel and replace the pressure plate. Yes, you might be able to get away without replacing the pressure plate, but do you really want to risk having to pull the transmission again if it doesn't work as it is supposed to? Several years ago I had a GTV come into the shop with a pretty bad clutch chatter. Yup, the clutch had recently been replaced at another shop. They screwed up a lot of things, and somehow the pressure plate was part of the problem as it didn't look like it had been replaced. Another clutch replacement and resurfacing of the flywheel took care of the problem.
