Hummer: I have a Hummer Truck starting to blow heavy white smoke from tailpipe

Thu, 04 Apr 2019 07:02:43 -0700

My Hummer truck has just started blowing heavy white smoke from the tail pipe only when I crank it. Doesn’t blow smoke going down the road. Doesn’t leak anything. The smoke kind of smells like oil or rubber burning. Stinks. Burns eyes. My temperature gauge has been increasing a little. It now reads about 210 consistently. Any ideas?
