Changed oil now white/gray smoke coming out of exhaust

I would check the oil level first also did you add the oil in the correct place? Also, if the air filter is not on right it can cause the crankcase ventilation system to suck raw oil into the intake. Here are videos on both job can you go over them to see if you did something wrong?

Please run down these guides and report back.

Hi and thanks for using 2CarPros.com.

Honestly, it sounds like a head gasket issue, but an oil change should not have caused that. Often times when a head gasket goes bad, coolant will enter the combustion chamber. When that happens, the engine will emit a white/grayish exhaust. Take a look at this link that shows how to check for a bad head gasket. Check what it says and let me know what you find.

Also, here is a link that describes what I mentioned and shows pictures of it happening. Read through it, too.
