In this video I show you how to change out the CCV’s Crack Case Vent Valves on my BMW E65 ( 750i ) BMW E66 ( 750li ). Similar if not very same on 6 Series BMW’s, and X5 BMW’s. This engine is the N62 8 cylinder V8

Fault Codes That Came Up before I fixed this (And NOW are gone) YESSSS
P2189 (system to lean at idle speed) Bank 2
P2187 (system to lean at idle speed) Bank 1

God Bless
