Guys, glad to see people are still using this guide, you're all very welcome. Wish I got on mbshop more often, just haven't in quite some time due to selling my E300.

Humzinger - with that many miles I'd consider pulling the head and cleaning it too, depending on the amount of gunk. Mine had minimal buildup in the intake ports, although I did stick some random tools wrapped with biodiesel soaked rags down mine to wipe out what I could.
