The inline five's back.

[John Larson]

Yup.  From the tone of your message, it appears you don't believe me, but
that's OK.  The tech simply breaks the chain, attaches the new chain to one
end of the old one, and turns the engine over by hand until the new one
emerges from the other side.  The tool assists in guiding the chain and
keeping tension.  We've had it for 15 years and have yet to encounter a
problem in it's intended use.  Made and marketed by Technics Tools in
Camarillo, CA, but also sold by companies like Baum Tool.
On the subject of VAG's design of the timing elements of the VR6, I have
nothing to give you.  Remember, some of these cars are approaching 6 years
old, and many are in the 150K mile range.    John
