I have a 1988 420 SEL. Upon changing the plugs, the passenger side were all in good condition, BUT all four dirver's side were very foulded up. The scope check seemed normal, all pistons firing. My mechanic said it is not the fuel distributor (?) but could need rings replace Ouch, but on 1 side only? Doubt it for sure. I know all the rocker arms were replaced on the passenger side, but not the driver side. Could this cause the problem? Maybe need a valve adjustment or replacement? She is not using any oil at all, and has 173,000 km. on it. Responses welcome and appreciated before I throw money in the wrong direction.
