Vehicle was dorman (uncovered driveway stored) for more than two years. Now, upon cold starting, light white vapor, which immediately dissipates, continues well after start. We tested it for at least 15 minutes. Mirror test confirms it's water vapor. Other than a leaking head gasket, are there any other causes of water getting into the fire chamber? Outside temp, approx. 69 F. Thank you for considering this inquiry. - Ralph & Kat

Head gasket. The reason for the cold then hot readings is the cooling system is getting gas bound by exhaust gases. A simple intake leak would just make you loose fluid, but wouldn't cause the other symptoms until the coolant was very low. Which leads me to, is the coolant full? The head gasket most of the time will not leak coolant into the oil, but instead coolant will go into the combustion chamber, and exhaust gasses will go into the coolant. You don't see any white smoke until the leak gets extreme. Then shortly after that the engine hydro locks from too much coolant in the combustion chamber. There is a tester that will test your coolant for CO gas. That is the proof of a head gasket leak.

As you've stated driving around town it's fine, and everything is working well. For the symptoms, there are 2 possible causes:
1. Your cooling fans are not working.
2. Your radiator needs to be replaced.
I'm sure you can determine which it is, and I wish you luck on your repair.

it could be the main relay, its notorious for the 91-93 models, so it might be that, and its the same symptoms.

not enough info. Typically, CO and HC together can be the result of poor fuel control or misfire, or worn components such as O2 sensor or catalytic converter, but without more data, repair recommendations are likely to waste money and not achieve success.
