Description

BMW chose an inferior o-ring material when building the S54. Over time, the Buna rubber hardens with heat cycling and oil exposure. If you see an oil leak that streams from the back of the block and down across your transmission bell housing, the CPV is usually the culprit.

The N15 Design CPV o-ring is constructed of Viton Fluoroelastomer and will retain its original shape and sealing properties for the life of the engine. This part eliminates the need to replace the whole expensive valve.

 

Note: O-ring only. Valve pictured for demonstration purposes only.
