Any idea what is going on?

Simple, your PCV system has failed, as in, the two hoses that go over the rear of your intake manifold are spongy, just squeeze them to see for yourself. When they get moisture in them and a hard freeze, they are restricted which pulls or sucks oil into cylinder, usually on driver side. That is issue I had several years ago. I ended up replacing hoses and the oil trap and PVC valve as part of your CCV unit, no other problems for years, so look there first and foremost.
