I add anti-freeze and it drains into the oil. People have told me cracked block, cracked head or just a head gasket. Please tell me what you think it is.

most likely your headgasket though, a cracked block is rare unless a con-rod went through it, a cracked head could happen after the car has overheated, and a headgasket could happen cause of many miles, and cause of overheating.

The head doesn't necessarily have to be cracked, it can just be warped bad enough to let antifreeze in. I'd put my money on head gasket though. Mine blew in the beginning of the summer and I had coolant in the oil pan. The guy I talked to at Phat KA-T told me the head gaskets on KA's usually blow in the back so its hard to see if anything is leaking.

also if your timing chain is loose it can eat it's way into the coolant system and drop coolant into the oil pan...Don't drive your car till it's fixed unless you wana blow your engine.
