Guys, thanks for the advice. I am going to spend next week trying to get this done - new single row chain, upper guides, tensioner and plastic oilers.

One last question, since I will have to remove the alternator for access to the guide pin, has anyone replaced the MB unit with a Delco CS130? Living in Louisiana (it's HOT!!) I want to add dual electric fans and I don't think the stock alternator will cut it.
