installed test pipe 2 weeks ago and there is smoke coming out my exhaust at high rpms.
after i installed the test pipe thats when the smoke appeared and im not burning oil because my oil level is at same level since i changed it. what color smoke usually tells when your running rich? can someone explain the colors running rich and burning oil please.

 

Running rich = black, there will be black soot on bumper/exhaust tip

Burning oil = bluish smoke

Burning coolant = white smoke

ok there is black **** stains on my exhaust tip, but not bumper yet. but the smoke is white so im burning coolant? so this means im burning coolent and running rich sametime...jeez.

 

but how is it possible burning coolent?

 

bump

 

look at your spark plugs

black=rich

white=lean

bronze/brownish=stoich

oil on the plug= burning oil

you are probably burning a tiny bit oil at high rpms and the cat is not there to burn off the smoke, this is normal, if you lose less that a quart between oil changes that is the standard amout vtec engines burn, Acura wont reccomend service for your car if it is burning that much or less

there is too much fuel entering the combustion chamber and being burnt

running righ burns out cats, o2 sensors, and can wash out clyinder walls along with causing other misc internal problems

thanx

 

My teg was smoking when i had a test pipe on as well. It also has a secondary o2 sensor that was left unhooked when the test pipe was put on. I got a carsound cat on it now and the o2 sensor is hooked back up again and no more smoke.

so if i switch back to stock cat i wont run rich anymore?

 

1 week ago i changed my spark plugs to NGK. i just took one of them off and the tip is black..is that normal?

 

Then that shows that you are running rich.
