It's not antifreeze, to further test this I drained the coolant and replaced with water.
Also, the oil pressure light used to flicker at idle, then it would come on full at idle, then it would come on even with engine revs, but not be on when the engine was cold, and now it is on all the time. This change would occur with the smoke, the smoke lingers for a long period of time in the yard/street. I've not driven it enough to know if it's losing oil, since it is smoking way too much to drive. The smoke used to be intermittent. Meaning that sometimes it would smoke upon startup and for a few minutes, and sometimes it would not. Now it smokes all the time, right from start up, engine sounds the same, it had good power, just a ton of smoke.
