Has your interior, mainly the passenger side, gotten wet lately?

Got into my car yesterday morning to run some errands and it drove great. I get into the car this morning, and it's missing and smoking like all heck broke loose. ...
By this time the car has cooled down. I start it up again, smooth as butter. Being optomistic I took it back out, and just as I pull out onto the road it starts smoking again.... just like it did first thing this morning. The smoke is mostly white, but I know for sure there's oil in it as well from this morning.
... the exhaust doesnt smell like fuel IMO. And leaving the pressure off (which i will do from now on) didn't seem to affect the smoke either. ...
Yesterday cars were leaving me 1/2 block of space for all the smoke I was pushing out. Today I get in it to do my laundry, and there's nothing wrong. After I did the laundry I took it up on a highway where I could actually get on it.... not a single lonely puff was visible from my mirror.
What the heck is going on here?
It does sound like head gasket problems, a small one maybe.
The car sits for a while, leaks a little coolant into a cylinder, you start the car and the engine begins to burn off the coolant, white smoke out of the tail pipes.
If your're leaving the top to the coolant recovery tank loose, the cooling system is not building up pressure, so when all the coolant that was in the cylinder/s gets burned off you only have very little or no smoke.

I agree, get the cooling system pressure tested. The engines bottom end could get damaged. The crank shaft bearings could get damaged. You could hydrolock the engine. If that happens let the car sit for several hours, then just "bump" the starter. You don't want to bend or break a piston rod.
Pay it now or pay it later.
