White stuff in oil cap

Ive discovered some white gunk in my oil cap. I automatically think head gasket, but am I correct?
No oil useage.
No white smoke from exhaust.
No obvious white gunk in water reservoir.
Mileage 55000km
Mostly does long trips but it is cold here at the moment and weve had heaps of rain/flash floods.
Also, recently disconnected oil/water heat exchanger around the oil filter. (Ill get that fixed over the next month or so). Dont know if that makes any difference.

Most likely due to the colder temperatures. If you get the white stuff on your dipstick then it's definitely head gasket.

engine condensate. (something i was trying to comment on another thread). i had this problem when my thermostat went. changed the oil and thermostat and its ok now. however it can happen even if the thermost is working. it only takes a little moisture to get the mayo in the filler cap. try changing the oil and go for a drive.
