I am going to check and adjust where necessary the shims in my 16V. Is a regular feeler guage OK, or did MB use a special tool?
Also, is there any performance/noise benefits of keeping the gaps at the lower end of the spec. gaps when cold, or maybe even a little lower? What about the racing versions, did they have the same gap specs?, or was there some emission control issues involved in the gaps being set at the factory specified level?
