Had a quick look online at a manual for this engine and came across the following;
MODELS E673L, S773L, N844L, N844L-T ONLY Add engine oil slowly. Pouring the oil too quickly can result in the oil overflowing into the air breather valve and then into the air intake manifold. Cranking the engine with oil in the manifold will severely damage the engine.
Is there a possibility the breather valve mentioned is missing or sticking?
Or maybe a baffle is missing.
The manual also stresses over and over to not overfill the oil.
I worked on a 6.2 diesel that had an oil issue and ended up connecting an external pump to the oiling system and pumped solvent through it with the engine not running and partially dismantled to locate the leak, in that case it was pushing oil into the coolant through a crack/flaw in the block.
