Hello everyone, I need a little help out there from everyone that can help?? I am having a slight problem on the right bank of my MB E420 1994 5.0 L engine. seems like a lifter is starting to make a clicking noise. 1St. Does the MB E-420 engine have solid or Hydraulic lifters in them?? 2ND. Does anyone out here have a picture of the top end, I mean showing the lifters cams and oil tubes, That they can e-mail to me. This would be a great help to me, before I start to pull the valve cover off. 3rd. Is it a real big job to remove the noisy lifter and replace it?? Are there any special tools for this removal for the MB.?? Again if they are solid lifters are there shims available for the lifters?? Not to sure about the MB engines, I have only worked on American automobiles and some Japan made autos. All of your help would be greatly appreciated. Thanks for reading this post. Ben
