Yes, the tool is needed to do it correctly without any issues. It's probably possible to do it without, but if the timing is off, then you will have to take everything apart again. There really isn't a spot to mark the gear to the cam, it's really close to the bearing cap. If you took off just the bearing cap and marked it, you would find the hook ring seals for the Vanos, I don't suggest you put anything on them.
