As my 84 300SD has 183K miles, I'm to the point were I want to tackle the timing chain. It seems like it is recommended that the timing chain tensioner and upper chain guide also be replaced at the same time. **************.com sells a kit with the aforementioned parts for about $134, which seems reasonable.
Thomaspin's wonderful site covers the basics of replacing a timing chain (albeit a different engine), but does not go into how to address the timing chain tensioner and upper chain guide.

Once I have the valve cover off, will how to address the timing chain tensioner and upper chain guide be obvious or do I have to tear down more of the engine to access these pieces? Is replacing my engine's timing chain as straightforward of a process described on Thomaspin's site?
Thanks everyone...
