I have been told that whenever I go WOT my exhaust blows out a white cloud of smoke I have yet to notice this but thought I would see if anyone has had a problem like this and what the fix would be. I recently have added Longtube Headers removed my cats and taken off my EGR and A.I.R system and was wondering if I might need to get my car re-tuned since the adding of the headers and removing the A.I.R and EGR and if that might be my problem?

 

I dunno but having the same thing told to me, but I have a turbo set up. I've seen a couple lsx turbos on YouTube blow smoke too.

 

I dont have a turbo lol someone mentioned that I need to install a catch can

 

you tuned your car yet?

 

I blow black/white smoke at WOT. Most of the time its 90% black. My car has been tuned also. I'm guessing its the removal of the cats that causes this.

 

i would agree.... watch this dyno vid, when i stomp it i got some smoke. i saw healthy ls1s that day doing worse. all tuned and none burning any abnormal amount of oil.

mine blows the blues at WOT. But only at WOT will it blow smoke. i also need to get a catch can, as ive got hella oil pressure and I dont think that is helping matters any.

 

mine also blows black smoke at wot i think its normal for ls1 cars

 

yep, similiar to what i've seen others do.
might need a good catch can set up.
the only reason it really bothers me, is i'm tired of people saying you beat me bad, but you are blowing some smoke.

 

Mine starting doing it after my tune, and my tuner is known for tuning rich and the car has no cats so i'm honestly thinking it's just a combo of whatever the cats usually catch and unburned fuel.

 

You removed your EGR thats the problem. You need to add a breather to your valve cover to ventilate your crank case.

 

That video looked normal to me... You are burning fossil fuels without any emmision equipment, what do you expect??

My old Nova smoked everywhere!! Disels blow huge clouds when they are tuned. I say if you dont want smoke from exhaust buy a prius!!


Lol but if your "smoke" looks like that video its normal.

 

what ? 01-02 fbodys don't have egr and don't have a breather.

 

OP has a 99 and the 00-02s do have a breathers from the intake tubing to the valve cover.

 

check your intake for oil

 

Damn I forgot about that since I don't have egr or air anymore. Good damn point

 

My 00 doesn't have a breather

 

You don't have a hose going to the valve cover from your intake tract?

 

That's a fresh air line for the PCV and all cars from 98-02 have this. Nothing to do with EGR...

 

Op says he removed EGR and air lines. It needs something to get air to the PCV system.
