Hi again,

I have the valve cover off and am staring at the cams and lifters. I would rather not replace all lifters. Do I just remove the torx bolts that hold the cams down and remove the cams then press down on the lifters to see which one is bad? Or do I have to actually run the engine first to find out what lifter is not lifting?

Also, is there any diy doc about removing the rocker arms on this engine?

I have the Technibooks "Mercedes W124 1985-1995" Owners Workshop manual and it has nothing about removing the cams/rocker arms.

Thanks very much,
Jim Lee
