There are several sources for step by step instructions. If I recall correctly Beisan had one. You can lower some of the risk of making a mistake by purchasing the Vanos rebuilt from Beisan. Periodically, ECS will have their timing chain kits on sale. You can choose OE, OEM or other mfg. parts. I suggest the OEM kit. I agree it is not for the faint of heart but with lots of research and taking lots of pictures along the way and a friend or two helping and taking your time it is manageable. The key is to use a good quality kit to keep everything in place.
