if you're getting tons of smokie, im pretty sure thats the problem.

One thing I forgot to add to my previous post. One way to tell if you are burning anti-freeze is that your coolant level will be low, obviosuly. You can test for a blown head gasket by pressurizing each cylinder with air. If you remove your rad cap and see bubbles coming up as you test each cylinder you will know that it is indeed a head gasket problem.
My advice is, if your collant level is low, take it to a garage and get it checked out. Most people don't have the equipment to do these tests properly and they aren't terribly expensive to get done.
