No thermostat? you have too

white smoke it caused by coolant, blueish greay is oil, and black is running rich.

No thermostat causes the motor to not warm up properly making it cooler and running richer.

a T stat wont hurt your engine cooling down it, it only helps it heat up to operating temp quicker. get a T stat. and you not having a cat may be the cause of the smoke.

i dont have a cat on my 1990, it smokes a tiny bit but my motors only got 1,050 miles on it.
