Constant Pressure Valve (CPV) o-ring plus tool • BMW M3 |E36 E46|

Replacement o-ring for BMW Constant Pressure Valve. Plus the tool to make the job easier.

Fits S50 and S54 engines.

Very often these engines have oil leak through CPV o-ring and goes all over the right side of the engine and over gearbox. To fix the problem it is needed to change either full CPV valve (much more expensive, BMW part number 11111318185) or just the o-ring.

Our replacement o-ring is Viton compound and is much more durable than original BMW o-ring

    - E36 M3 - Euro
    - E46 M3 - Euro and USA
    - BMW Z3M (S50 euro engine and S54 engine)
    - BMW Z4M (S54 engine)
