My 92 500E has some 96,000 miles. I have heard various comments on change intervals for the timing chains. We recently replaced them on my 380SE and simply rolled the new one in.

How complex is the timing chain replacement on the 500E. Can you roll the new one in? If so, can I or should I replace the rails as a safety precaution under the understanding that the rails are plastic and in a heated environment may have become brittle? Can the rails be replaced easily or is that complicated.

I enjoyed the guided tour on the replacement of the distributors for the 500E. Is there a similar guided tour for the timing chains.

Thanks

Dwight
