I just reviewed the section on best practices again.
 Are you guys using a gob of RTV at a point near the center of the bolt or
 is
 there a rubber grommet available specifically for this purpose.
 My bolts had some type of rubber looking substance on some of the bolts
 (not
 all) but they were much worn so I removed it during cleaning.

 Put a spiral of red  RTV all along the tension bolt.

 This damps the vibration and prevents the bolt from
 fatiguing at the root of the threads where it screws
 into the front housing.

I tried to put a spiral or glob of RTV on the tension bolts, but it always
got scraped off when installing the bolt and made a huge mess without doing
any good.  It also makes it much harder to remove the bolts and clean the
passages.  Bits of cured RTV get everywhere.

I think Lynn recommends shrink wrap to dampen vibrations.  Most of mine
don't have anything.

Perry Mick broke one and we spent three days looking for the source
of the internal coolant leak out in hot Palm Springs.

Sections of shrink tubing with an O-ring between each?  The shrink
tube acts as a spacer.

What's the OD of the bolt vs. the ID of the hole in the housing?  The
O-ring should fit tight to the bolt but be slightly loose in the
housing to allow for easy install/removal.

McMaster-carr has a nice selection of rubber washers which might tend
to stay in place better than o-rings.  I'm sure o-rings tend to roll.

You could let the RTV dry before installing the bolt..  Then it
wouldn't be stuck to anything but the bolt.  You'd still tend to get
bits of RTV pealing off though.
