Help for a 1991 Calentamient problems

Hello: I am from Mexico

first in advance greetings

I need help I have a 1991 Cavalier I just bought but it turns out that this evil is heated, it takes it to a mechanic and says it is the engine head packaging.

They could help me to know how I know that is true and if so, they think the packaging comes out.



Thanks in advance

The diagnosis is easy, Cheka the oil and rod cover if they have a white or yellow average storm, it is because the water is passed to the oil, if the water is right if the water has oil is the packing of the lid, if there is a precion in the water storage are also the three failures that are there, there is a fourth cheka that does not come out white smoke by the escape, that indicates water in the combustion.
