Iam stumped. Here is my delema, I can see WHITE smoke coming out of the exhaust, I checked everything My car doesn't over heat, the thermostat does open, the fan turns on, I cant see any mixture of oil and water so a headgasket is out of the question, keep in mind that my radiator is too old its the stock 90 CR-X Si radiator, my exhaust piping is 1 inch with a really old cat, ( until I have enough money to change all that) I can hear a lil bit of back firing and water spurts out when I rev until 4000rpm ( too advanced right?) I know for a fact that my timing is a lil bit off. So if you can help me out, please do. TYIA.

 

Maybe its jus cold out side because i see a lot of white smoke on mine...2 weeks ok my radiator died so I changed that and the thermostat..week later my radiator crapped out again this time really bad no coolant engine got hella hot in minute. Changed again now I'm hoping it will be fine now. It takes forever to heat up now lol my problems are never ending. Are you sure its backfire and not jus the exhaus tone. That water is jus condesation...You should be fine man...
