Excessively underpowered 1HZ + poor fuel economy

Leit - Where did you plug the pre-oiler on the 1HD?

Reading this thread sent chills down my spine as i am dealing with a similar issue. Few days ago, i have finished rebuilding a my 1HDT after a catastrophic turbo failure which filled the engine with aluminum shavings from the compressor wheel. At this point, when trying to prime the engine with oil, in 5 second bursts with glow plugs and IP 12v disconnected, i get no pressure on the factory gauge (somewhat expected), the aftermarket madman multi gauge with a VDO sander installed into a sandwich adapter before the oil filter. furthermore, when i removed the filter, it is empty. Filled the oil pump with substantially more than the required 10cc and using a syringe, filled the passage prior to the oil filter.
Thoughts....

I would have thought it would have taken around 20 seconds of cranking continuously to get some pressure. With 5 second bursts , it may not quite get there.
If all the parts were dipped in oil during assembly, I would be inclined to start it, or at least crank it for longer periods.
Is it pumping any oil into the valve cover?
