Original BMW PCV Oil Separator Valve Grommet for BMW M5 and Z8 S62 (2000–2003)

On the S62 V8 in the BMW M5 (2000–2003) and Z8 (2000–2002), this Original BMW grommet seals each crankcase ventilation (PCV) oil separator valve to the intake manifold collector. BMW calls it simply a gasket. Each one weighs 8 g and is made in Germany. BMW has produced this number since September 1998. The engine uses one grommet per valve and two per vehicle. A crankcase ventilation system routes blow-by gases from the crankcase back into the intake to be burned, so any gap at this joint lets unmetered air into the intake.

Original BMW Parts carry a 24-month parts warranty.

Since this grommet sits between the oil separator valve and the collector, replace it together with the valve. Fresh grommets at each valve keep the joint free of vacuum leaks after the job. Each grommet is sold individually, so a full set for one car means ordering a quantity of two. The same part is used in both positions, so you will not need separate left and right numbers. BMW's data ties this number to the S62 engine only, which keeps the choice straightforward for M5 and Z8 owners.
