I used Thomaspin's site for my chain replacement...'bout the best resource you can have. You can also do a search on this topic...countless posts have been written on this. If you replace the lifters or "cam followers" in MB speak, from what I hear if you replace them, you have to replace all of them AND the cams. Someone else here more knowledgable can confirm or deny this. But I don't think that the cam followers would lead to it missing.....am I right? You may have other problems, such as ignition components or fuel injection system. Let us know what happens.
