what is the maximu timing chain stretch ? 500 SE

[AfricaXJ6]

HI All

on a 1991 Mercedes 500 SE, Is it possible for the timing chain stretch to be 15 degrees?


with both the cam timing marks spot on the pulley shows 15 degrees.

the car lacks a lot of power , and can hardly move, yet the engine starts and revs ok, slight miss can be heard.


I read on this forum that a maximum chain stretch is 11 degrees.

so it seems 15 degress is possible ?

, and obviously taking it pass the safe point




any thoughts?
