Time to replace timing chain?
I have an '81 300sd with 275,000 miles on it. The car is immaculate, it appears that the previous owners took great care of it and it has very little blowby. I was thinking it might be a good idea to replace the timing chain as preventative maintenance. I was told if the car was treated right and always had proper oil changes that the timing chain should never die. Is tis true?

well maybe
but the chain can be checked for stretch. if it is not stretched it can just keep going. you might also want to take a look at the chain guides. they often wear out before the chain.

double chain
that engine has a double chain...
why replace a double chain.... two chains, two chains in one.... if you have to do something just replace the tensionior and the chain guide... |

Check the stretch.
I just checked my 603 and I am just shy of 4 degrees at 254k. Since this is right at the limit of spec I'll roll a new one on. MB specs 15 degrees with an upper limit of 19 for a 603.
