Hopefully never.  The timing chain for the VR6's was designed with the
durability needed for a diesel version, so I wouldn't be surprised if they
last for a couple hundred thousand miles in our gas cars.  It's a dual stage
chain; the crank sprocket drives the oil pump/intermediate spocket with one
chain and this in turn drives the camshaft sprockets with a second chain.
AFAIK, changing the chain requires removing the trans, since the chain is on
the flywheel end of the engine instead of the serpentine belt end.
