White mystery smoke. Happens intermittently with no real rhyme or reason.

No compression test numbers.

Okay so about a week ago I topped off my oil and gas tank, checked my coolant, etc etc. I drove home and everything was fine. The next day when I started the car, let it warm up for 5 minutes, and drove to the store, as soon as I revved to get to the end of my driveway, I look behind me to see billows of white smoke. It looks like I just seafoamed the damn engine there is that much smoke.

My first thought is I blew the water jacket or something and I'm dumping coolant. But the smoke doesn't have a sweet smell and the coolant is at the same level. Well I turn it off and check the oil, a little under the full mark but mostly where I left it. I took the air tube off and the maf out, blew on the maf to clear any dirt out, and wiped any excess oil from the intake overflow. Just a little oil.

When I start the car this time I get no smoke. So I think I fixed it with the maf/intake issue. Well fast forward to tonight. The exact same thing happened and I repeated the cleaning and it went away again. Could it just be doing it while the engine is cold and when it is fully warm it stops? Could the maf be causing an issue? I'm checking the plugs in the am but the plugs and coils were changed OEM about 15k miles ago.

Any direction y'all can give to look for let me know. Trying to avoid taking it to the dealer for another couple months.
