I have a 09 Chevy Malibu 2lt 3.6l vvt v6 and everyday when i start my car there’s a thick white cloud of smoke that just shoots out my exhaust. After like 5-10 secs it stops and it stalls just a little bit at first but when I drive fir a few mins it runs and dives perfectly. I’ve checked coolant and oil. Have no idea what it could be. No weird color in the oil. Maybe a little dark but I probably just need a oil change. But no leakage or anything that I can physically see. I just don’t wanna go to a shop and have something big and expensive be done when it could’ve been cheaply done at home. Anything would help just in a tight money situation and can’t quiet afford an expensive fix. There’s also this picture some line and it seems to have a slight leak but don’t know what it is.
