No oil to top end

No. Everything on the motor was untouched and unmodified from factory. All we did was intake gasket timing chain and oil pump and put it back together. (With new gaskets ofc) heads were never off it either.

We managed to get the oil drive gesr out today. Trying to find stuff to make a tool to try and prime it with a drill.
What is the chance you got the pump mounted "askew" and bound up the intermediate shaft?
