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?
From the details that you have given the problem is either a blown head gasket or a blown head. THIS SHOULD BE REPAIRED IMMEDIATELY! This is caused by coolant getting into the cylinder and coolant being burned. That is why it is a very chemically smell and burns the eyes. I would suggest taking the vehicle to your local mechanic and they can do the repair. This repair should only be done by someone that knows what he is doing.
The things to check to verify the above suggestions for repair would be your coolant level. Check it when the vehicle is cold and see if it is lower then it should be and if it is getting lower. Also pull the oil fill cap and look on the inside of the cap, is there any milky buildup? If so you are getting coolant in your oil.
