I was gonna mention getting the Vanoa air fitting as well to check its movement .

Try eBay , you can get cam locking tools on the cheap there .

The important tools, in order of importance are:

1) Cam locking blocks
2) Flywheel locking pin (or 8mm drill bit)
3) sprocket turning tool
4) Chain tensioner
5) Vanos air fitting (you can make your own by cutting an old oil hose)
