White smoke is a good indication you have a blown head gasket. And/or a cracked head. Did you noticed, when it happened that the engine started running rough? Best i can do with little info.

Check engine light is on1998 Isuzu rodeo ls32 v6?

the check engine light means you have something wrong with your emissions. theres something wrong with how your car lets out exhaust. There are sensers on your exhaust pipe that sense how much exhaust is being let out and how much unburned fuel is coming out. There is a computer in your car that senses that and try's to fix it. one of your sensers might be bad or you might have a clogged catalatic converter.

Car is suddenly loud and the check engine light is on?

The check engine light comes on when the computer detects a problem and sets a code. You need to have it diagnosed with a scan tool. The loudness may be an exhaust leak. the o2 sensors will pick up the change of exhaust gases and set the Check engine light.
