I've been at rebuilding my 240D awhile, so I'm not sure I'll be able to stand the smell of gasoline long enough to do this, but I'm about to change the timing chain, rails and tensioner in my 300E, for peace of mind reasons.

I assume that the masterlink on this chain is bradded in place with the special tool just like the 240D. If so, is it the same tool as the 240D? Also, it appears that by pulling the top front of the timing chain housing, the rails etc. will be exposed. Will removing the top part of the cover allow me to change everything? Should I change the tensioner at the same time?

According to the records, the chain, and apparently only the chain, was changed on this car before. After reading some of the comments regarding rails breaking, I've decided to replace rails and chain, so I can enjoy myself while driving the car, rather than worrying about it.

Tbanks for any help anyone may offer.
