Get The repair kit from i6motorwerks
This is the video that people have been requesting for so long, this is the video of rebuilding the Vanos in your BMW car.
The seals I got as a kit from i6motorworks they had the stage 3 kit that had everything I needed to do the job without fucking around with shit. the kit worked awesome with no issues even to today.
so if your having vano issues with your bmw e46 this job is quite easy but it’s a big task as there is lots to take apart.
