I've changed my chain and all of the guides which can be replaced without removing the timing cover. I did not change the cam sprocket Just how important is it to tear the entire front off a 617 to replace all this stuff. Yes, my 84 300 SD......

'Cell' did a great job on that explanation.... Your questions have to do with variables which are not usually findable.... did the prior owners use the correct oil, correct filter, and change those at proper intervals ? Usually what you did... roll in new chain and replace those things reachable without taking the front sheet metal off will keep the car going just fine... It is a judgement call having to do with things like the cost of a good replacement engine(assuming they are still available at that time in the future ) from the salvage yard or a parts car...which may or may not be easy to access AT the time in the future you need one...
In general ... if you have the space and the money and run across a good parts car... snap it up now... by definition they are getting harder to find and will continue that trend...
