I have a 1999 Mitsubishi Eclipse. It seems to be running fine. It does not over heat. It may have a slightly rougher idle to normal and white smoke is coming out of the exhaust. Also, after I let the car idle for awhile the smoke seems to chill, but a little bit of water seems to drip out of the exhaust. When I drive if (after it is warmed up) I believe the smoke starts a little more heavily. I do not understand the issue and dont know what I need to do in order to get it checked out. Ive tried the "bubbles from the radiator cap" to check for a blown head gasket and there arent any bubbles. I level in my reservoir does rise as the car warms, but Im not sure If that is an issue or if that is normal.
