Sorry to hear all this has been going on and the obvious hasn't been detected by a shop. All those parts probably would not of had to be replaced. This is a classic systom of a blown head gasket. Not every head gasket blown will have coolant in the oil. Compression leak from a cylinder will enter water passage in head and blow out the coolant because compression is greater pressure than coolant system pressure.
Check add plastic coolant tank hose to radiator make sure it isnt clogged and then check plastic tank for depris ie brown texture if plastic tank is ok check that level in plastic tank isnt too high .....add up to a max mark
