Your likely getting water in your oil as well. Could be a cracked head, but most likely a bad head gasket.

Like D17 DAVE it could be a crack head or head gaskquet but could be too the gasket behind the water pump and oil coler

Oil cooler is behind water pump , the head gasket could also be leaking or a cracked head as they do crack between the injector copper tube and the valves. could also be one of these copper tubes are bad.

As the head gasket seals the compression by being compressed by the liner protrusion from the block and the head , the rest of gasket just seals the water and oil passages .

As it is not a pressure cooling system it's hard to trace leaks .
