My engine is smoking white smoke smells of antifrezze. The problem started when the temp. Gauge went to high after I pulled over, shut the engine off then turned back on the temp. Went to normal. Coming home the same thin happened. I noticed the over flow bottel was full to the top and the rad. Hose was not that hot. I changed the themostat and the and checked system with a pressur tester did not lose any presure (when cold) the problem still exsies. Now when coming home the car started missing and smoking. Could the problem be headgaskit or intakegaskit. If not for the down turn in the economy I would buy a new car so if you could help me I would be very thankful Thanks Larry
