- Oil check valve
Fig. 59: Oil check valves in the cylinder head
Three oil check valves are inserted into each cylinder head from
the outside. This prevents the engine oil from flowing back out of
the cylinder head and the VANOS units.
As the check valves are accessible from the outside, there is no
need to remove the cylinder head when changing the check
valves.
