Yes, it can.
Probably a blown head gasket
You may not see anything on the gasket. Usually a head gasket "blows" because of overheating that causes the head to warp. A gasket can be bad but there should be a visable break very often in the ring around the cylinder.
Most likely you have a blown head gasket.
Take it to a mechanic nobody can tell you how to replace a head gasket over answers.com it requires someone who knows how to rebuild engines when a head gasket blows it requires the engine to be disassembled and rebuilt.
Usually when a head gasket blows, there will be a lot of steam coming from the engine. you may also see blueish smoke or cloudy looking oil.
No not hardly. The only thing that stuff will do is stop up your heater core and radiator. They have never made anything in a can are bottle that would fix a blown head gasket.
Probably has a cracked block, too :(
You can warp or crack a head or blow a head gasket but I'm not sure how you blow a head. More info please.
A good way to tell is change your oil. When a head gasket blows you will have water in your oil or oil in your water system. Check these 2 areas for water and oil.
sounds like you need a new head gasket
The head gasket has failed and will need to be replaced. The head gasket seals the place where the engine block and the cylinder head meet, there are many oil and coolant passages in that area, so when the gasket blows out the coolant in the nearby passage vents into the cylinder closest to the failure point.
