Do we HAVE to replace the bolts with new ones? Those alone cost more than the gaskets and tubes combined!...can they not handle one more tightening?

You don't have to replace the screws. But, you do have to replace the seals around the screws. And those come as one part on the S65 (assembly). It's a bummer. On the S54 engine and others, the seals are available separately...
