These are true "interference" motors, so jumping time is a major problem. You can even get one of these engines with the correct timing into trouble by just rotating it backwards by hand. The limit of cam deviation values (how far they can be off the correct timing as read by a PIWIS/PST II/Durametric system) is -/+6 degrees, one tooth on the drive gears is more than twice that amount.

And, yes they will turn over with holes in the pistions, etc. Rotation is only stopped when debris in the cylinders or crank carrier jams the sytem.
