I thought I would change the help change the plugs on a friend's '98 E320. We managed to remove the plastic engine cover (Just pulls off)
There are two plugs per cylinder. Plug wires seem to disappear into a clamp like fitting Plugs are not visible but must be down inside there somewhere :)
What is involved, (a) removing plug wires and (b) removing plugs in tight space. Any special tools required?
