Scarry Oil Pressure
However the oil pressure sender unit is at the back of the intake. Is it possible to may have knocked this causing it not to function. Its quite fragile if knocked.
I think the next step is to remove the intake, and see what the sender unit looks like (make sure is not wobbly due to being knocked) and check the wires too. May be an idea to check the intake isn't cracked while you have it off. There is a GM part number for the rear coolant block off's with the front crossover pipe, I would convert the coolant lines while the intake is off.
Inside the oil pressure sender unit is a diaphram, if the sender unit is wobbly there isn't anything holding in that diapharm, I'm sure if you had enougth oil pressure it would blow it out. Is your oil pressure reading high or low. If the sender unit is cracked I would expect it to read low oil pressure.
