The E39 and E38 with the M62 engine can have issues with the timing chain guides.  The plastic on the guides that the chain runs on, becomes brittle with age.  In the case of the vehicle in these pictures, the plastic on the upper guide was completely gone when we got it apart.  You can see the difference between the old and new guide.  Also if you look closely you see the chain resting on the guide with no plastic at all.  This can cause serious noise issues, and if not attended to, can also be detrimental to the engine.
