The white creamy substance inside the oil cap comes from moisture in the engine that doesn't get burned off because the engine never really warms up. The moisture is held in suspension in the oil. The solution is to get the engine hot enough every now and then, as short trips are the usual cause.
Recommend that you change the oil, get it good and hot, and then change the oil again. That will usually clean it out.
The oil separator freezing is caused by the same moisture in the oil as I have described above, but the oil separator isn't causing it.
