If you have smoke in the ER, the elbow may not be installed right. If you're gaining oil with diesel in the pan, then look at places that have the two in close proximity. That is usually a mechanical lift pump, but can be the seal on the injector pump. It also can be a bad injector tip flooding the cylinder with diesel beyond what the engine can use. Since the engine won't take a load, you're probably running on 2+ cylinders, that looks like a prime direction to look.
Replace the new injectors, one at a time, with an old, known to be working, injector. Start the engine, apply load. Do this one at a time until you find the bad injector, or it doesn't solve the problem. Then you need a mechanic.
I doubt you had water in a cylinder with the broken elbow. The water had an easy path out of the engine. Unless with the new elbow, you cranked and cranked with the seacock open and back flooded a cylinder. And in that case, you would have gotten a hydraulic lock and the engine starter wouldn't turn over the engine.
If you use the method of opening the injector nuts to find the bad cylinder, use lots of rags to catch the diesel and use liquid dish soap to clean the diesel off the engine and rid it of diesel smell. You don't have to open the nuts very far. Just enough to release the pressure. That results in the injector's valve remaining shut and doesn't open, that cylinder doesn't fire. Injectors have a spring loaded valve that prevents combustion debris from getting into the injector.
