These seals replace the poor BMW seals and are made of Viton and last way better than the Buna BMW used for the seals...
this kit also includes all the internal seals that BMW do not sell separate so you are insured that all your seals are 100% and will remain so for a long time...
the install procedure for this engine needs you to set timing so it is beyond the scope of your average DIYer
S50 Double Vanos (Euro E36 M3)
A new valve cover gasket will need to be fitted if it has not been changed within the last 50 000km to avoid oil leaks this can be got at BMW or the workshop doing the work
