Anyways. So, I bring the car home from a 70 mile trip. Somebody told me about smoke coming out when I revved the car. I went to McDs for lunch today pulled out of hte parking lot and look back and see a cloud of white smoke behind me. It didn't follow me, just under acceleration it leaves a plume of smoke. I asked the guy how long the car had been sitting and he said about 4 months.

Do you think its just condensation? I DID make a 70 mile trip and I thought it would have gotten out. The headgasket was recently replaced when the head was rebuilt so I think that factors that out. So what else could it be?

do a compression test and check your turbo to start with

 

[MrBoxx]

Check for shaft play on the turbo compressor wheel. Wiggle the compressor in and out, up and down, etc. If it wiggles in and out, the turbo is shot. Any noticeable wiggling up and down, or side to side, means that the bearings/seals are probably on their way out and the unit should be replaced ASAP. Check the oil level regularly.

Make sure you know what you're burning. Does the smoke smell sweet like coolant burning? Or does it smell like oil burning? Do a compression test and leakdown test if the turbo checks out okay.

White smoke you should be burning coolant. Check your coolant level every day see if your loosing any.

Compression test will narrow it down a lot. See what she reads and go from there.

Oil level is fine.

I apologize, but I'm new to the turbo world. To get to the compressor wheel, do I just take off the big tube connecting to the side of the turbo and the fan wheel will be inside?

It smells like coolant.

UPDATE:
It doesn't smell like coolant or oil. I actually found out its black smoke and the check engine light came on...

O2 sensor?

What code is being displayed? Black smoke is fuel so that would be a good guess but get the code to be sure.

It was a fuel trim code at Autozone. Said it could be the injectors, something in the fuel system, or the o2 sensor. The o2 sensor is my best bet. However, the smell coming out of the exhaust is also coming out of the engine...

Here's a video.

The smoke doesnt shoot til after the car revs. It shoots white, then black.

I seem to be having the same problem. it won't do it until i get on it a little and it in mid rev it seems to shoot black smoke. theres also black soot all around the bumper above and around the muffler. my buddy whos real intelligant about dsm's suggested it being the 02 sensor.

 

[srtcrazy]

It's probably the O2 Sensor by the turbo. Had the same problem... gas mileage went up and light went away after I replaced it.

 

[brian9397gsx]

yeah when my 02 sensor failed i also got fuel trim codes, i would deffinantly start there.

 

[djtrickstick]

compression test and leak down test first, if he replaced the headgasket it was most likely smoking before, so what i do is waste gas and time if you have some and put it on jacks on level surface and just let it run till it warms up and look at everything i can to see exactly wats smoking and where from.

Black smoke = burning fuel
Blue/tinted blue smoke = burning oil
White smoke = burning coolant

 

[MrBoxx]

As I've mentioned hundreds of times before, white or gray smoke CAN be burning oil in the exhaust system if the turbo is blown.

 

[EagleT97]

Black smoke = burning fuel
Blue/tinted blue smoke = burning oil
White smoke = burning coolant

also white smoke can be ATF fluid in some cases.

Sorry to thread jack, I have the same problem and nobody has responded to this in a while. My compression is 180-170-175-175, and I am not burning any coolant. There is normal side-to-side shaft play in the turbo and no in-and-out. Help!

 

[SnprSlick]

Alright, I got my o2 sensor replaced. the car still smokes. I got a good look at it, and the oil is blue tint. so its oil. I check my oil and see its reaaaaally low. So I put some in. After about a week of driving, the oil was reaaaaally low again....
