You can't damage that engine by turning stuff, but you have a mess
on your hands now.
Crank mark up, cam mark down, but there are several cam marks, and then
the distributor turns counter clockwise, on the 16V and clockwise on the 8V
so you need to keep that in mind while turning the distributor for timing adjustment
If you watch the #1 cam lobes (front of engine) you should be able to tell when
you have the right cam timing mark down, as both rocker arms will have a slight loose
tick, or use a feeler gauge to check them
