    6.0 powerstroke help

    Ive got an 05 6.0 with a strange vibration. Vibrates at high idle only. Does it while driving and in dead brake. Is worse when loaded. Any thoughts.

      Ive done heads and a turbo on this truck but no removals. I recently put a tc for this issue but no luck. I also warrantied the turbo. Fuel pressure looks good and no misfires on my scanner while vibrating.

          look at the harmonic balancer, check if the outside ring has spun.

            I saw one of those a couple of weeks ago.

              Thanks for the replies guys. Oil pressure is normal and the balancer looks very smooth.

                Sometimes you need to get more technical with vibrations to avoid tossing parts.

                  Pull the belt to rule out something in the front possibly, like the fan?

                  The first thing that comes to mind is the rear crank flange. You say you haven't pulled anything so I assume this isn't the case. But if that has ever been pulled, say to install a rear main or something (unnecessary, but it happens), I'd almost promise that's your culprit. It clocks your flywheel. Plus its bolted on before the crank is machined. So it should never be unbolted.

                  In case you or anyone reading isn't aware, there is a trick to releasing these belts. The tensioner has a little tang that will hold the tensioner. Pull on the belt below the alternator to draw back the tensioner and press the tang in, let go of the belt, the tang gets wedged in, holding the tensioner open. No need to rename the truck with 4 letter words trying to get a tool in there any more.

                    Thanks for all of the input. Ive got it fixed. It was 2 injectors. I recently updated my solus and for some reason it is not registering misfire data correctly. Also have a verus and compared the two and there it is. Ive taken a pic of the two screenshots to show u guys.
