whitish paste in carter ventor

For a few days, since the cold wave began my car loses refrigerant due to the water pump and water sleeve and I have seen that it also has a whitish paste inside the tube that goes from the carter to the air filter, can it be a button joint? or gets water that loses in the carter?

Hello, very good, look at the first place that loses antifreeze will not be a problem as long as you do not stay without water and the engine, the white pasta of the vent has a better paint, you have noticed than the engine oil is clean or at least black, because the oil turns white when mixing with water. If so for the car immediately because you load it. all the best

In principle, the oil comes out black as always and in the vessel of expansion in refrigerant is not mixed with oil, it is perfect, it will have something to see that the antifreeze leak is close to the box where the carter's breathtaking tube goes?

What car is it ????

It is a Seat Ibiza 1.4i 98 gasoline
