White exhaust smoke


#1

2000 honda crv, 165k puts out white smoke a few minutes into idle, particularly with a/c running. had mechanic try cleaning out (i think) fuel injectors but said success was 50/50- white smoke persists. smoke continues for a while after selecting “drive” & then subsides… what’s the cause, is there a fix?

It’s normal when you start the car in the morning, especially cold mornings. If you live in snow states, you see them everywhere during winter driving. It’s actually the condensation (from the previous day’s hot engine) that’s being burned & coming out thru the exhaust pipe.

Well fuel makes black smoke, not white. White is moisture (H?O).

As noted on cool or damp conditions moisture may condense in the exhaust pipes and show up when you first start it in the cool morning.
