11 15 1 703 484 : Cylinder head cover breather for BMW Z3 (E36)

This cylinder head cover breather is a replacement part intended for the BMW Z3 (E36), in its Roadster and Coupé versions equipped with the 2.8 M52 engine, for vehicles produced until September 1998. It ensures crankcase ventilation by regulating blow-by gases between the cylinder head cover and the intake circuit, contributing to proper engine operation and joint longevity. As part of the restoration or maintenance of a classic example, replacing this ventilation valve makes it possible to correct oil leaks or pressure losses related to a faulty breather. A simple but essential part for keeping this roadster in impeccable mechanical condition.
