What they said; (1) cam bearing (you are sure that's right) (2) head gasket oil hole not punched (extremely rare) (3) 2nd from front dr pedestal prob (bolt/shaft hole issue or clogged) (4) shaft orientation (you were sure of that) (5) shaft plugged up (could be but it is new) EDIT Since you're dead in the water I'd pull the plugs and have a helper down below hand turn the crank with a 1&1/4" socket/short extension/breaker bar as you up top (re) drill prime & hopefully get oil when he hits the sweet spot (cover the pedestal w a rag if the shaft is off). Never had that accident but seen it happen
