Hi everyone,

It is as simple as this. Whenever I warm up the car for 10-15 min without touching the throttle, then go press it hard, I get a black(maybe grey or blue) smoke out of the exhaust. Does it mean I've worn cylinders? or is it because of the valves adjustment?

I uploaded a video on YouTube to show the problem [media]http://www.youtube.com/watch?v=0oX5JGG8uMw [/media]

I want to know if it's something that can be fixed without a big mess.

Thanks all,

 

I think your fine. Looks to be just black smoke from running rich. And I see you have an 01, those thend be on the rich side.

 

Is there a solution to this thing?

I've been reading about engines running rich since you have answered, and Someone suggested changing the exhaust. I was about to change mine, and if it's a solution to the black smoke, it will just make me do it sooner.

 

you are running rich. typical ap1. when i had intake and full exhaust and revved it up like that there would be a good amount of black smoke, same as that. my motor is perfectley fine. just get it tuned.

 

my ap1 doesn't do that. no cat either.

Maybe valve seals? Do we have neoprene valve seals?
