You need to get some sort of a service manual, even a cheapy Chilton book will do wonders to help you get familiarized with the workings of the overhead valve Mercedes V8. The one I have is quite good at giving steps and diagrams on pertaining to exactly the above questions you have.

Most of us are more than happy to help anyone out around here, I just feel you need to qualify yourself somewhat by doing a bit of research on your own.
