Coolant draining out of exhaust pipe

I own a 1983 Nissan 200sx. It has been sitting for a few years. After fixing some leaking hoses, I attempted to fill the radiator back up but would drain very shortly after filling it. I looked under my car and a very steady stream of coolant was draining from my tailpipe about as fast as I had poured it in the radiator. This is with the car completely off and cold. It seems to simply drain from the tailpipe and I can't figure out what is causing this, Please help.

--Vexxed-- Oh, you have some big problems, my friend.

I would not start this vehicle.

Coolant is getting to the combustion chamber in larger amounts than I've ever heard. It must be a huge crack or hole in your head or block to be letting that much coolant drain through.

It sounds like it's time to pull the heads and see what's up. Car Repair Talk's forum.
