Seafoamed the ML!!
I used the instructions from here:

Well I did the Seafoam on the ML this Saturday. I decided to do both the crankcase and intake manifold. The valve tap is still there although it's much, much better than it was before. I'm thinking I might have to change to a slightly thicker oil weight later on.
I bought only one bottle when I should have bought two since I did more than one method. What I should have done was use half to maybe a full bottle of the Seafoam through the intake and a whole bottle for the crankcase. I ended up doing 1/3 bottle for the intake and 2/3 for the oil. As a result, not as much smoke as I expected (much less than I expected) and less than the videos you might see on Youtube.
After I did this the ML seemed much more eager to rev and just get up and go. Being a 3.2L V6 in a 5,000lb SUV, any change will be significantly noticeable and this was. I plan on doing it again probably this summer or next year when the next oil change is due and this time I'll put the correct amount through the intake.

I was adviced against seafoaming by my trusted MB Mechanic..
I just called my mechanic to ask his opinion on doing this, since I too have a 100K+ ML.
His opinion was, anything that removes carbon build up sounds good, but if any unseated carbon particles were to squeeze into the valve openings or something like that, this could quickly become a very big project and it might do more damage than good.
Not worth the risk...his 2 cents...

Yeah, my family owns a garage... and when I originally explained it to some of the mechanics there they were hesitant to help me do it. When they saw, felt and heard the results though they were pretty blown away... It doesnt break the carbon off in chunks... it more like traps it in the vapor and then burns it off, if that makes sense
One of the best things is that my engine idles Stablely at ~550rpm and is so quiet that with radio off, heater fan etc off... you dont hear the engine running... a 5.5liter AMG engine running silent... is pretty amazing. This is the second time I ran this... the first time I didnt do the crank case treatment, and Im sorry I didnt because it made a world of difference...
