Rein Camshafts for BMW Z3 (1996-2002)

Clear BMW chassis

The camshafts are responsible for opening and closing the valves in time with the movement of the pistons. Sometimes the lobes can become worn or scored, necessitating a replacement of the entire shaft. Performance options are also available with more aggressive cam profiles that allow increased lift and duration.

This is the o-ring used for most BMW camshaft sensors and crankshaft sensors. Although most sensors that we sell come with this o-ring at no charge, they may be the source of oil or fluid leaks.
