My version of the story (from my mechanic/god) is that the 10V NA
engine if officially non-interference, but it close enough that if
the belt breaks at high revs, there can be a little valve touch
due to the extra extension from the speed of the valve movement.

It is unlikely that damage will occur, but if it lets go at 90 on
the highway, it could happen.
