[QUOTE=JordaanDMC-12;2024678]I went back a few hours ago to the mechanic and he said he had adjusted the idling. The idle adjuster on the dash was "out of whack" as he put it and now it's actually adjustable but it still didn't fix the problem.

How do I check for the valve clearances? I'm taking the car back in tomorrow so I have all day today to play around with it.


Valve adjustment in the archives has step by step approaches. Basically it involves removing the valve cover and checking with a feeler gauge for the right clearances.

With time, milage, and no adjustments they tend to close or tighten up. Mercedes recommends a clearance check every fifteen thousand miles. Some of these old buggies have not been checked for a dogs age.
