I got a 97 integra, and whenevr it hits vtec my car throws hella smoke out, its whitish balck so i assume its gas, wht could be the problem? Im running test pipe, bult head, air/fuel controller, i assume it may be the settings on my controler but not sure about that. plese help

 

could there be a coolant leak? whitish smoke is usually the scene of a coolant leak somewhere. blackish smoke is probably an oil leak somewhere. perhaps the head gasket isn't on right? what head gasket are u using with your ls/vtec? were u having problems like this when you first had the work performed on your vehicle? btw, i don't know if u have ls/vtec, i'm just assuming that from your nick name...

 

could be blow by.. My car does the samething. make sure it's not running too rich, and keep an eye on the oil. If it happens only in v-tec, and at higher rev's most likely it's just blow by. Also the straight pipe doesn't help with the black smoke either.

 

ya i think my car is running to rich, its a GSR not an lsvtec that was my old motor, need to et it tned right, any other help.

 

How's the oil level in between changes? I think it's just the straight pipe, cuz I've seen all sorts of cars blow out blackish smoke. The whiteish smoke moght be from some oil but nothing major. I'm not sure but an oil catch can might help with reducing blow by.

 

my teg does the same i have a intake DC 4-2-1 header AEM pullys JET ECU.
i burn a little oil (depending on how hard i drive it) it also has a slight tick. do y think it could be the valves i dont think they have ever been adjusted. oh i also have a full DC exhaust.. btw its a 99 GSR. ive been to a couple of local shops but only one said anything worth listing to he said its running to rich and thats the black soot im getting on my bumper cover. any ideas whats the prob. 56,000mi

 

Most cars run rich when floored, so you get black tips on your exhaust. Heard that by installing headers. and exhaust on Hondas, you run rich. It's normal. So don't worry about it too much. My tips gets black after 2-3 days of flooring it. It's a Greddy sp.

well i get a little more than some on my exhaust tip. its all over the back of my car . im thinking about changin my plugs and o2 sensor.

 

try the plugs. But it really depends on how the muffler tip sits. Mine is in enuff so the bumper stays clean. I also drive a white car, but then again I wash my freakin car every week.
