The shortest anybody so far seen a chain break at is 34K mi.
Your engine is destroyed. These are interference engines and the
pistons and valves bang into each other. Best case you bend valves
and gouge pistos. Worst case the valve ead breaks off and gets mached
into the heads ruiing them and the block as well.
Keep in mind only the US got single row 380's and only for
a couple of years.

just change the chain or not.
this thread is repetitive.
you obviously prefer mercedes's information to the info supplied by
everyone else. if you won't let yourself be convinced, there is no need
to post further on the subject.
on a final note, changing a timing chain in a 380SL far from makes it a
piece of crap as you stated in an earlier post.
If you studied this entire thread, you will find independent Mercedes mechanics
who are on both sides of this issue. Some of these independent mechanics are
adamant that the chain must be replaced ASAP, others that it can exist but
replaced every 50k or so miles. I believe that all the viewpoints were
presented based on what they truely feel is the best thing to do based on their
experiences. I respect all their opinions and wanted a forum to work this out.
That is a rather vague statement that can be construed both ways.
the only independent mercedes mechanics on the goofy (single chain OK) side of
this issue are those whose experience is too limited to provide a
representative sample of failures, or are too young to remember that these
engines experienced timing chain failure even within the original warranty
period (36 months/36,000 miles).
