How can you tell if the headgasket in a 91 Honda CRX is bad?

I believe if you see white smoke when you start your car or if there is a lot of white smoke coming from the exhaust, this means you have water in the oil. Check the oil and if it appears watery then you have a blown head gasket.

THAT IS TRUE, BUT NOT ALWAYS THE GIVEAWAY, COULD BE BLOWN BETWEEN TWO CYLINDERS WHICH WOULD CAUSE NO SMOKE BUT LOSS OF COMPRESSION. YOU COULD CHECK THAT WITH A CYLINDER LEAK TEST OR MAYBE A COMPRESION TEST

  • jwko - steam from the tailpipe means that engine coolant is being burnt off in the cylinder with the air/fuel mixture! Use a compression tester to test each cylinder, if you find two cylinders with low, even pressure that are side by side then you know. Also could be a crack between cylinders. Keep in mind not to allow the engine to start while using a compression tester...remove all the plugs! The bottom line is, if you see steam from the tailpipe on a warm day you have a bad head gasket. if you see a milky like substance in the crankcase ( on dipstick or under oil cap) you could either have a bad PCV valve or a leak internaly.

A complete air conditioning system install on a 1988 Honda CRX has the potential to costs thousands. Everything would have to be safely installed and checked to make sure it is street legal. A bad install can lead to poisoning the community.

air leak in the throttle or intake manifold gaskets or bad TPS sensor, disconnect TPS as a temporary fix

Your headgasket is bad, coolant is getting into the combustion chamber, hence the thick white smoke and fluid. had that happen to my dads thunderbird a few years ago
