300sd Timing chain replacement question.
I am needing to replace the timing chain on an 83 300sd (250+k). There appears to be 5-8degrees stretch. On this site's DIY chain replacement link, it does not say to change the chain's tensor. Dieselgiant's link say YES YES YES change the tensor (which adds a lot of extra work).
Any thoughts on this? Is there pros and cons to replacing or not?
Thanks
