Does cracked.header cause.smoke ?

[raider89]

Can a cracked exhaust header cause smoke to come.from exhaust i also notice smoke from the.crack.

Coolant level is good and.oil looks good.

Its a pretty decent.crack and.the smoke is very light can see it.if u really look at the muffler, but.its.pretty.noticeable from.the header

yes it can. exhaust leak pre cat will make the o2 think youre running lean then it will pump more gas in. fix your header
