Hi There, I have a 1993 Honda Civic DX. Of late when I start the car the whole body bumps and the engine temperature soars as indicated by the temperature gauge. On the first occasion it gave thick white smoke from the exhaust and the hood. There is a characteristic burning smell too. I bought the car 6 months ago when it had 93K miles on it. I had replaced the timing belts then and as of this day it has 97K miles on it. The first time around my mechanic gave me the car back after keeping it for 2 weeks and said that there is nothing wrong with the car. The problem recurred. This time around the mechanic says that the head gasket is gone/blown/broken. He says it would cost a minimum of 0 to a maximum of 00. Are the symptoms really indicative of a head gasket problem?. Would it cost so much to fix it?. Being a graduate student I really cannot afford to fix it spending so much money and then later realize that the problem was something else. The mechanic also says that when the head gasket is fixed one has to replace the timing belts too. Is this necessary considering that I just recently changed the belts. Need advice. Thank you.
