passing smog test

anyone got some tips on how to pass an emmissions/smog test? if there is white some coming out of the exhaust? i heard that i should put some anti freeze in the gas but i have no clue
please help :cool: :cool: :cool: :finger: :bandit: :alien2:

Warm up your car before you go. Go on the freeway for maybe 30mins. I don't see how antifreeze would help really, but I don't see how it would hurt either. Its essentially just alcohol... perhaps some high octane gas would help too???

1) Do a complete engine flush (formula 1 makes a decent engine flush, so does AMSOIL).
2) Put in some fresh (cheap, as you are gonna drain it soon) oil and a new filter, run the car for a little while, drain that oil and put in new oil and another filter.
3) Check your pcv valve to make sure it is functioning properly.
4) Retard your ignition timing before you get tested, and when the testing is finished correct your timing.
5) Make sure you have a functioning catylitic converter, and emisions control system.
6) Never tried this but if your really desperate to pass, try placing strategic exhaust leaks upstream of the tailpipes...not sure if this works though as I think they test in parts per million, exhaust quantity may not make a difference.

if really desprate go to a junkyard and get a seccond cat
