RE: What hapens when you drop a belt on a 16v?

RPM has nothing to do with the damage factor. Jareds car stuffed the valves
at 30rpm. Its dumb luck you did not stuff a valve. My friends Jetta stuffed
them at 2000rpm in 20mph traffic. Regardless of RPM on a 16V your pistons
and valves are sharing the same space at diiferent times in the chamber.
There ARE points in the cycle that you could stop the motor and suffer no
damage, but at anything above 100 RPM you chances slim to none, its russian
roulette.

Again this is very rare..you were lucky.

A 8V is a non-interference motor, in that the pistons never travel into the
path of the valves. A broken timing belt in a 8V would simply result in a
non-running car.

Why is this? Is it because the 2.0 has a longer stroke then the 1.8?
