Vanos seal replace was maybe 6/10 difficulty. It was one of the most satisfying DIY repairs I ever have done. There are other parts of chain guides job they are more difficult.
It's very difficult to get one of the internal Teflon seals in. 8/10 or 9/10 if you try to do the way they suggest. If you use my trick that part becomes about 5/10 difficult. I would still get three of the Teflon seals to replace 2 just in case of learning curve emergency.
Basically, there is a thin Teflon seal deep inside a groove. Then a chubby o-ring goes in after to maintain pressure on the teflon. The Teflon being the slipperiest substance known to man is very difficult to get it to stay down in the groove while you work your way around.
After chasing the thing around the circle several dozen times and wrecking the first teflon seal I figured out a foolproof way.
