This is a valve cover repair kit for BMW/MINI N13, N16 and N18 engines, supplying the crankcase ventilation diaphragm and spring that the manufacturer does not sell separately from a complete valve cover. Replacing just this worn diaphragm resolves rough running, hard starting and increased oil or fuel consumption caused by a failed crankcase ventilation seal, without the cost of a full valve cover replacement.

Fitment: BMW 1 Series and MINI Cooper S with the N13, N16 or N18 engine, covering the F20, R56 and R60 chassis.
