    Great to see inside. Tjx for shooting n posting that. You've inspired me to hey a scope camera, I should be able to diagnose a lot just by.pulling the injectors n manifolds off my diesel kzj78. Just a note, though: your link to Amazon just points to some random 4 pack of batteries....

      Ah, you're totally right! I just fixed the link.

    Another informative video! Really opens questions in my brain as to just exactly what my own operating and maintenance procedures should be as I accumulate mileage on my new engine.

      On anything I own that I have rebuilt or baselined, I typically keep a simple schedule. Oil changes every 3500-4k miles, full synthetic w/ OEM filter. Startron Enzyme fuel system cleaner every 4 tanks of gas. Coolant flush and PCV valve every 15k miles. Drivetrain fluids every 30k miles. For me personally, that has seemed to work well, but some may say it's going overboard.

      @@NKPGarage My exposure to aviation and aerospace strongly agrees with the frequency and intervals you lay out. In addition, because I am so completely base lined I can't resist the satisfaction of trying to lay out a life cycle schedule for everything else. Thinking I would just add an expiration mileage or date column to my build sheet beside each necessary part number. My wife mentioned that we have never loaded a plane with a big heavy toolbox 😆before heading over the mountains. So maybe we can apply the same preemptive maintenance approach to the cruiser.

      @@DouglasGreen562 That's a very good comparison. The last thing you want when you're a couple hundred miles away from civilization is a mechanical problem. People think I go overboard on my boat maintenance as well, and in addition I carry spare parts on the boat like alternator, water pump, cap/rotor, spark plugs, belts, and some other things. Every time over the years I have had a failure that has left me stranded, I have used it as a learning experience to add that failed part to my box of spares I carry, and also to modify my maintenance schedule to make it more bullet proof.

      Thanks bud! It was an interesting experiment to see what is going on in there

      I guess anything is possible. Maybe? But, I think the HG is sealed up okay. In the last video I did a full leakdown check at 100psi and there was no leakage past the headgasket into the coolant tract or oil tract. The only place I found leakage was past the exhaust valves in two cylinders where the exhaust valves were not shutting all the way.
