When you disassemble the vanos unit to replace the piston seals there is a metal seal between the housing and the covers that bolt to the housing. I had these seals manufactured specifically for the, no one else has these seals. I felt that if someone was going to all the trouble to replace the seals it makes sense to properly re-seal the housing.
