        Replace it. After installing one, I don't think a tensioner is needed with a quality double roller.

          Wow. My guess is that chain is designed to be used with a tensioner.

          Since you have it open might as well switch it out to a roller type.

            That chain is dust! Probably hitting your timing chain cover too. You just answered my next question which was if there are 2 hatdened Torrington bearing races on the Milodon....I only got one with mine.....that 1 bolt hole you see on plate is the adjustment bolt you need to drill and tap into your block. Buy a new silent chain and tensioner and be done with it. Cheap enough. Even double rollers 'stretch' and will cause cam as well as ignition timing variances. Tensioner solves variances in timing but not the stretch inherent in any chain. Although some would argue the strength differences in the 5-7 plate silent type chain and the 4-6 plate double roller. Often the cogs wear , not so much the chain stretching. Iirc $$ . Rollmaster uses hardened cogs as well as a IWIS chain.

              Factory spec says to get all the slack on one side and no more slack than 1/2". You have well beyond 1/2".

                I did a similar video of my 3.9 Magnum in my Dakota.

                    It was clattering against the cover.
