Yes, this can be done. Caveats: Match weight of new piston to weight of
removed piston as closely as possible. You might get very minor vibration
at high RPMs. (the overbored cylinder is making .0001 HP more than the
stock ones) Keep the difference between overbore and stock as small as
possible. (+.010" will be OK, +.500" won't be.)
Sure, it would be nice to do them all, but sometimes it just isn't possible.
This sounds like you're trying to bail someone out who needs to fix their
car as inexpensively as possible. The "standard" solution, as you are well
aware, is to do all five, and of course the dealer's answer will be to buy
a new A6 at full retail and junk the old crock.
Desperation is the mother of invention - no used short blocks anywhere at
the breakers? A 5 cyl Audi block is a $50 item here . . .
Interested in this situation - keep me posted!
