11 0 091 Installing Replacement Engine (S85)

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2010 BMW M6, 2010 BMW M5, 2009 BMW M6, 2009 BMW M5, and 2008 BMW M6. However, it is still accessible from the selected car via links, so may be relevant.

Necessary preliminary tasks: 

NOTE: Use a 5W-30  engine oil for the running-in procedure in a replacement engine.
Running-in engine oil must be changed at 2000 km for a 10W-60  engine oil incl. engine oil filter.

Installation: 

Modifying check valves, refer to memory entries in DME.

In engines where it is not possible to connect check valves, replace the vacuum-controlled check valves with self-opening check valves.

Vacuum lines will then no longer be required.
