I drive it everyday I just did a piston soak so maybe its all the [censored] coming out. I wouldnt think it would still be doing it
Some cars shoot "black liquid" out of the exhaust that appears to defy all conventional explanations.
Its not Head Gasket smoke
it MAY be fuel smoke (but its not smoke)
It IS black and it is liquid
it drips out of the pipe
and it stains the ground as ink when it appears.
Then it goes away.
I too have not been completely been able to explain what that stuff is, nor how it gets through all that piping, past a cat and muffler, to the tailpipe.
Might be carbon might be gas but its "black liquid." literally then it stops.
Havent seen it in awhile but i have heard people with old Chevy trucks say they ruined their pants walking behind their truck when it used to do that. So its apparently an (old) GM thing. And again idk what it is.
