Replace spark plugs in a BMW 760li 2004 - 2007 BMW 760Li Sedan

I have listed a generic spark plug replacement procedure that will help in spark plug replacement. You must pay attention to detail when performing this procedure. I apologize for the delay, my internet connection is not so great today. I would also recommend a BMW service manual for future reference as well as other repair procedures.

On M50, S50, M52 and S52 engines:

Remove the valve cover trim fastener caps, the remove the fasteners securing the trim to the valve cover.


Remove the oil fill cap and place a clean rag in the oil filler cavity to prevent debris from falling into the engine. On M50 engines it may be necessary to remove the fuel injector rail trim cover before removing the valve trim cover. The fuel injector rail cover is removed in the same method as the valve cover trim.


Release the clips for the coil pack electrical connectors, disconnect and place the coil wiring harness aside. Make sure not to note the correct location for each coil's electrical connection.


Remove the fasteners securing the coil packs.


Note the coil pack location for correct reinstallation, then carefully lift the coil packs upward and set aside to expose the spark plug hole cavities.








If compressed air is available, blow out the recessed cavities in which the spark plugs are located.



Use a spark plug socket and extension, and place over the spark plug. Loosen the spark plug 1 / 8 a turn (45°) counterclockwise and if compressed air is available, blow out the recessed cavity in which the spark plug is located a second time.


Remove the spark plug. Inspect the plug and plug gap as outlined in this section, and replace as necessary.




To install:





Check and adjust the spark plug gap as necessary. If the plug has dual electrodes, the gap should not be adjusted, and if out of specification the plug should be replaced. Always check the gap of a new plug to make sure it hasn't been damaged during packaging or shipping. Some spark plugs come pre-gapped and should not be gapped. Consult the spark plug's manufacturer for plug gapping information.


Apply a light coat of an anti-seize compound the threads of the spark plug, unless directed otherwise by the spark plug manufacturer.


Place the spark plug in the socket or use a piece of rubber hose placed over the spark plug porcelain to place the plug in the spark plug hole.













To install:





Installation is the reverse of the removal procedure, making sure to correctly route the plug wire and make sure it snaps into place when installed onto the coil and spark plug.

Ok, but that is close to procedure although it may not be exact. What issue are you having? Finding the spark plugs? Not sure what to disassemble? Ok, but that is close to procedure although it may not be exact. What issue are you having? Finding the spark plugs? Not sure what to disassemble?
