Could be a couple of things, the intake gaskets are a known problem with this engine, it could be sucking coolant right into the combustion chambers when running and the other is blown headgaskets also a common failure, you should look at the engine oil if it is milky colored then it is very likely that the headgaskets are blown, a block check will verify this. If the oil is milky and the block check says the headgaskets are fine then it is the intake gaskets.

Need to get it checked because it sounds like it's leaking into the combustion. Cracked head, block or bad head gasket

With the engine cold, pressurize the cooling system with a pressure tester. The system should hole the pressure for 15 minutes, minimum. While you're waiting, especially if the pressure is dropping, carefully look and listen for the leak. Is the coolant level going down in the radiator or just the plastic recovery tank? HTH. -Jim

It's done, have it crushed.
