"Valve adjustment is an art as much as a science. Remember, you use "feeler" gauges. You have to learn the proper "feel" of the gauge at the correct adjustment. That said; the only way to learn is to do it several times. I suggest you get someone who has done it before to guide you through the first time."
I always found doing valve adjustments an oddly pleasing task. Something about the way the feeler gauge slides through the gap...it's very hands-on and tactile. I haven't done it on a Mercedes, yet, but I've done it on aircooled VWs and on a Honda Civic. The Civic was easier -- I didn't have to lay down on the ground to get to the cylinder head.
