  1. The video was a little blurry but at 13:20, that wagon that Dan commented on parked in the back of the abandoned car dealership looks like a '57 Ford Del Rio Ranch Wagon. Those were stylish 2-door wagons.

  2. Awesome machine! It's nice to get an easy fix every now and then. Sorry to hear about the crank balancer failure. When it rains it pours ya know. Short tow and relatively easy fix= the good kind of bad luck, if you know what I mean. P/S I don't know that I'd be in a hurry to get to central Florida right now. The approaching hurricane sounds dangerous.

  3. Scott he should change the vibration dampers, cones and front seal. If the dampers are bad it can break the flywheel bolts and or break the crankshaft not an good idea to ignore this problem dampers are cheap compared to the crankshaft,

  4. Harmonic dampers are one of the hidden disasters on heavy diesel engines. Some are fluid filled, the fluid goes hard, goes out of balance and destroys the crankshaft slowly over a period of time.

  5. Man, there was no way to find that damper crack without actually disassembling it. Older car and truck dampers need to be checked regularly because the rubber ring does wear out. And sometimes there are final balance pins in the damper that must be transferred to the new damper to preserve smoothness.

  6. Kept us all in suspense about the second breakdown! It was running so sweetly the whole video. What a great bus. Never get tired of listening to those engines. My cousin's boat has twin 400 HP Cummins but they sound so boring! Thanks for the update.

  7. I'd love to see a resto mod on that 6-71. It would be awesome if someone manufactured a common rail conversion for these. Unlock some extra ponies and/or tune it conservatively for fuel economy/longevity.

  8. I’m glad to see a good outcome. Remember that if you’re having to add coolant and don’t see leakage on the ground you better be looking for where it is being lost. Pull your oil dipstick and make sure you don’t see it there or that your oil level is not abnormally high. Look for evidence in your exhaust pipe for burned coolant, in some cases it can even find its way into the fuel system.

  9. Hello. What is that bar that they hold with a pressure clamp? I love watching your videos. In my country Uruguay, they were called two-stroke engines. I was always in love with GMCs. In fact, someday I would like to drive one

  10. Great video Scott… wonderful memories the time you and i spent on Dan's property working on our buses in his pit , amazing dinner and sitting around the fire ring eating home made cookies… wonderful people and a special time…
    Sitting here in the bahamas now all tied up getting the outskirts of the hurricane and praying for all who will feel the effects much worse…
    Hope all is well in your world and give that beautiful woman of yours a big hello and hug… miss you all…
