It's a bad pcv /oil separator it has a Reed valve gets hard and breaks or quits working. Replace that by taking the upper intake off to get to it behind the engine back by the firewall on driver side. Then re route hoses going to throttle body on top of intake to prevent I've build up Google the tsb on it it's pretty detailed. All caused by ice blocking airflow blowing out camshaft cover gaskets
Could be pcv valve...ck to hear ball inside rattles when you shake it . if not free it will cause pressure to build in crankcase an it releases thru any where it can......oil filler cap. thats why the filter is there..escape path for pcv failure.
Sounds like you have too much Crankcase pressure. Check to see if your PCV valve is functioning.

Looks like a head gasket failure. Oil is escaping out of the engine and within the engine into the coolant passageways. The oil pressure system is run at higher pressure than the coolant pressure and fortunately this has so far kept the water from entering the oil and crankcase. I have no faith at all in any after-market product that claims it can repair leaks by simply adding it to the coolant or oil and taking a head off is not a trivial task. It may also be that the head has warped (this would also cause the leak) and this in turn will require it to be re-machined. Head gaskets are not expensive but due to the work involved this could be one occasion when a visit to a machine shop is the best option.
