It's time to replace the timing guides, rebuild the 2 vanos and replace all the stuff that I should while it is apart. I have read several threads, googled it and watched some youtube videos.

I have the following questions:

Which DIY instructions have you successfully used. Is there a useful video?

Have you rented rather than purchased the special tool kit needed? If so, where from?

It sounds like there a lots of opportunities to do or fail to do something that will require taking it apart again to correct? What do you think is the best way to avoid the land mines?

I would use BMW parts. Is there a better quality alternative?

Thanks in advance
