Good to hear most of you have collected your Beisan vanos seals kit. Trust all of you will take this opportunity to have your old vanos seals replaced asap. The new teflon vanos seals should provides an over all increase in torque, power, and a smoother transition throughout the RPM range.
Seals break-in
When new, Beisan teflon seals will have a rough milled surface. After a period of use, the contact surface will be polished and have lowered contact friction. Thus at initial installation teflon seals will not perform well, but their performance will increase progressively in a short period. Optimum performance can be expected after 800 kilometers of city driving.
