97 2.4l dohc

I have a 97 cavalier z24 with a 2.4l dohc in it. I bought the car with a blown motor in it so me and my uncle overhauled the motor. After that i was messin around and spun the bearings on crankshaft. Now i have a new motor in it but for some reason it seems to be smoking white from the exhaust. and once in a while it almost dies from the idle.  Im thinkin the idle air controll sensor is messed up anyone got any tips?

yeah i agree with andrew, white smoke usually means anit-freeze is getting in the cylinders

I have tried to figure it out and my only guess could be is that on a brand new motor the rings in the number four cylinder havent seated yet because i checked the spark plugs and the number four cylinder is soaked in oil so i think that the white smoke is oil burning in the number four cylinder idk?

when u see the smoke, does it have almost a sweet smell to it or does it smell like something burning?

if its more of a burning smell then that means its burning oil, oil must be getting into the cylinders somehow. check ur compression and if u can, do a pressure test with a spark plug pulled out and see if theres any kind fluid getting in but it does seem like a head gasket might be shot
