TRNW-2: 10R80 teflons

[pat schulte]

I have done it both ways, original rings and replacing them all. I am
currently on the bandwagon of airchecking them when I pull the VB before I
disassemble. While I am airchecking the packs, I am finding many times they
will aircheck dead tight. If so I leave the rings alone, otherwise I change
all of them. I have found on airchecking the new rings, if you get them wet
and then hit them with full shop air pressure they will many times leak a
little but holding the air to them they will all of the sudden pop and
seal tight
