From the details that you have given the problem is either a blown head gasket or a blown head. THIS SHOULD BE REPAIRED IMMEDIATELY! This is caused by coolant getting into the cylinder and coolant being burned. That is why it is a very chemically smell and burns the eyes. I would suggest taking the vehicle to your local mechanic and they can do the repair. This repair should only be done by someone that knows what he is doing.
