Very interesting...
Great detective work, thanks!!

Also interesting that the problem applies to the N62, the 4.8L as well as the 4.4.

Something to look out for in a few years: as Milligoon suggests a preventative replacement of all the rubbery bits around the inlet manifold might save some greif.
