If your chain is rattling severly I would recomend replacing all the parts related to the
timing chain, but if you are doing it just because the mechanic said so I would take it to a dealership and have them check it out. A lot of the indepdent shops are trying to make as much as they can on every little job. You can actually replace the chain by feeding it through the top and using a master link. I know BMW does not have a specific link for the e30 m3 but a 2002 chain link will work if your just trying to make the engine last until you need a total rebuild. I know for a fact that BMW SEATTLE will do it and Strictly BMW in Bellvue WA. I would not put a master link in a M3 engine you plan on racing though. The reason it cost so much to do the job
without using a link is because you have to remove the front covers, which is a real pain in the ... If your chain has been loose for awhile have them inspect the guide rail for damage. If no damge is visible I would just go the cheaper route, and save your self over a $1200.00 .
