As I was just looking at the upper timing chain rails for the 380sl on
several websites, -- e.g.,
and http://www.thebenzbin.com/parts/?N 159+4294966701+1668+7281) --
I happened to notice that there are plastic rails made by Swag for
$4-5@ and metal rails made by Meyle for close to $20@. However, I did
not realize this when I changed my rails several years and app. 40-50k
miles ago. So, I used the plastic rails. Of course, had I known then
that there were metal rails, I would have used them instead --
considering how crucial they are to the engine's timing, and the
plastic ones' tendency to crack with age.
I was therefore wondering if the metal rails are new, and if other
people have also replaced their rails with the plastic ones -- either
because people didn't realize that metal ones existed, or because the
metal ones don't have a big advantage for some reasons.
Thanks very much for the info.
