Posting in the wrong section can kill your 420A.
The reason the timing belt breaking will cause damage on a 420A is the same reason it will cause damage on a 4g63 - there is not enough room in the combustion chamber to have an open valve with the piston at top dead center. It is a valve-piston interference design. if the belt breaks, any valve that is open will collide with the piston top when the piston moves towards top dead center. A Jetta uses a 2-valve overhead design and interference is not an issue because the valve angles are closer to perpendicular to the piston. Ours are closer to parallel.
