This BMW B58 PCV Diaphragm replacement cap comes with all the necessary hardware to replace your old or leaking PCV Diaphragm cap. The BMW B58 PCV cap is prone to failure with vehicle aging and mileage, as the rubber portion of the PCV cap will naturally dry and begin to crack over time. The PCV diaphragm cap is subjected to constant negative pressure, as a result, any cracks or leaks in the rubber seal will cause engine malfunctions. A replacement plastic end cap is also included in this kit, as it is not uncommon for this portion to be damaged upon removal.

Replacement cap doesn’t fit.

Overall the kit is worth the affordable price. The diaphragm fits as the original does and material seems identical. The part that doesn’t work is the replacement cap. Try as I might it would not stay on. Which was fine since I had the original cap and snapped it back on. Just be aware if you purchase this to be careful when removing the original cap so you can reuse it.
