I was just messing around with the car and noticed that the car is blowing out a large amount of white smoke everytime I hit the throttle. I don't even have to rev it high, just 2-3k and a pretty large amount of smoke comes out.

Any ideas on what could be causing this? The car has been known to eat oil, about a quart or so every 1000 miles durring the summer.

Anyway I can fix this?

 

How long ago did you put the headers on there? And are you accumulating a large amount of black soot around the rear bumper where your pipes exit? If this is so you could be running really rich...same thing happened to me after my header and catback install..

 

Sound like oil in the intake manifold. Maybe a catch can would help some.

 

The headers have been on since last November so I don't think it's because of that.

Oil on the intake manifold?? I just had the oil changed a few days ago. Do you mean a little over spill or something?

 

Hope you're not getting blow by

I agree with DaleMX about oil in the intake manifold.

Check your Throttle body for any excessive pooling of oil. Could be a bad PCV system or worse; rings.

Does the smoking occur evenly at all times or more severely at high rpm's? Any weird noises from your valve train?

How hard do you drive your car and how often?

 

I have 18k on the car....and I drive it pretty hard.

Just checked the car again and now its not really smoking anymore...maybe oil in the intake?

I'll check the throttle body for pooling of oil.

 

might check your PCV valve too.

 

You need a crankcase evacuation system for your motor. When you put headers on, you changed the dynamics of the engine. The crankcase evacuation system will run a negative pressure (vacuum) in the crankcase and works well with the LS1's low tension rings.It will improve ring seal, and add ponies to your power output. If you're running a high volume oil pump, get rid of it. That could also be the cause of the smoking.I have friends that are participants in cirle track racing, and they won't use high volume oil pumps. They just use, when they have to run a wet sump design, a blue printed oil pump. High volume pumps rob horsepower,and add heat to the oil, by the increased pressure they put out.

 

My car does something similar, smoking at high rpms and moderate throttle, and smells like oil burning. I was thinking valve seals but what exactly is a crankcase evacuation system??? Im probably gonna replace the pcv valve cuz thatll be a helluva lot easier than valve seals.
