i had a b18a setup on my crx and it was doing it also just because my headgasket was blown. Now that i have replaced my engine to a b18b, the tailpipe is still smoking. anyways here's my setup on my 89crx si --- 94ls w/ ctr high compression pistons(brand new), new headgasket and valve seals, and im using a 90ls computer, intake manifold and injectors basically a obd0 setup. I started it up last night and water was coming out the tailpipe. The plugs are pretty dry and there no leak anywhere, i dont have a check engine on my dash, i used a 91 octane gas and put a octane booster, i retarded the timing just a little bit, and a new o2 sensor but there was water coming out the tailpipe. What could be the culprit in this case? btw i grounded a wire from one of the radiator wire so that the radiator fan always comes on whenever turn the car on. your replies are very well appreciated.. thanks

yeah but my car has been in the garage for awhile

Condensation in the exhaust is normal. My car pees when I leave the garage

Now if it's enough to fill a small bucket you've got a problem...

another thing, the catalitic converter produces water during its chemical reactions....

its silly to always have ur radiator fan on. 1, it wastes alot of power because ur alternator has to put a heavier load on the engine to produce the electricy to turn the fan, and 2nd, ur engine does a good job of keeping itself at the right temp. The engineers designed the motor to run at around 180-220 degrees. They do this because metal expands/contracts at different temps. So let ur engine keep itself at the right temp.
As for the smoke, drive around and see if it goes away. It sounds like u just have water from it sitting.
