Priorities right? Just like how the US government sticks soldiers in combat zones driving hummers with the worst light diesel ever made. WTF?

The International Association of Fire Chiefs has petitioned the EPA to drop the requirements for fire and emergency equipment but they have not received a reply. Imagine that. I will try to find out what happened, but Ford authorized a long block with just diagnostic testing this time. Although the first dealer looked at the injector which was fine. After several steps of the new testing, prior to tear down, the long block was approved. The engine knocks really bad like a rod hitting the block, but in these engines, who knows.

On a chassis designed in the '70s, carrying rifles designed in the '50s. I could go on and on, but sadly that's not the point of this thread. Feel free to bring it up in Club FTE though.

At this point any accusations regarding the emissions equipment are conjecture at best, we don't know what brought down this engine yet.

GM, Me and the FIL have wrote the director of the EPA about that same issue, obviously one county wouldn't do it. I think I told you in the other thread, but with one of the 6.4s, we made it shed a little bit of weight. Lone and behold, zero problems since then.

We may never know what happened as the Ford tech was doing the diagnostic testing, he got to a point and was entering the data into the Ford computer system, when it said "Long Block Ordered". Ford did not authorize a tear down this time, so it looks like it will be a mystery. However, upon cranking the engine, no rough idle like an injector, no smoke, just a very heavy and loud knocking that you can't even tell which side of the engine it is coming from. However, the engine is to be crated and sent to Ford. Will try to get more info if at all possible.

How is maintenance tracked on this truck? I'm wondering if the oil has suffered fuel dilution or viscosity thickening from idling, wiping a bearing?

These trucks are tracked by hours and mileage. 200 hours or 5k miles. None of the 6.7s have ever "grown" any oil, but that doesn't rule out a possible stuck injector that either fluid locked one cylinder and bent a rod, or just what you mentioned.

UPDATE

The new engine is in, although not starting yet, possibly due to PATS system(for some reason the new ambulance packages have PATS too), and the old one is out. When it was removed, it had a crack in the block, that was just starting to leak, around the crankshaft in the front on the side near the number 5 cylinder. What ever happened, was involving the crank and that cylinder apparently as it looks like the crank was moving in the block a little. Whether it fluid locked number 5 and bent the rod and crank is only conjecture, but it was in the front and on the left side and in the front. The injector for that cylinder appeared fine when it was removed. I'm not sure you guys know this, but a new crate engine from Ford is complete with everything down to a new turbo, but DOES NOT come with new injectors. So the new engine valve covers have to come off to install the old injectors(or new if you want to pay for them).
