The valve adjustment will be due on my 1982 300D in a few months and it will be the first time I've done one on this car (or any other car for that matter). The procedure looks reasonable, and I've got some of the special bent wrenches on the way to help with the task.

I'm wondering if you noticed any change in engine noise, better or worse, more or less, after the adjustment?

Not that it would make any difference in my adjusting the engine to spec, I just wonder if going from "no clearance" to specified clearance would make a valve tapping sound.

Thanks,

Ken
