You are getting moisture build up in the block. Some moisture is always happening, but if your Ventalation system gets plugged or broken, that can let the moisture build up and give you the slimmy white mess. Hope that it isn't anything major like a head or gasket.
I would start by checking your PCV valve, it is quick easy and cheap to fix. Good luck

Good advice. In earler model cars it was loss of vacuum to the crankcase resulting in moisture build up. Same can happen in new ones but hose, valves etc must be looked at also.

How does the underside of your oil cap look? The milky brown water/oil mixture can show up there too.
