run some tests. or since basically all 3 will require a tear down, just dig into it and visually inspect. but i'd compression test it and see which cylinders are the problem ones first, to give you a start on where to look.

Run engine without the radiator cap and see if your water level goes down? If it does and not leaking from hose or radiator it could be crack head or hole in back of timing chain cover, Otherwise just needed burping letting out the air in the system ?

I have the same issue after a complete rebuilt of top and front end brand new cylinder head and all water still going directly into oil pan I can see the water trickling right under the oil pump / main seal and crank when I look down into the timing case with the valve cover off if that was the case with mine would the water be entering thru that area I did notice wear on the too of my timing cover where one of the guides had broken from the slack ?
