Today for some reason when I would 1st start up my car I would get clouds of white smoke pouring out my exhaust when I pressed the gas. Even if I drove it around, and shut it off for a few minutes I would still get smoke when I restarted my car. My car is catless so I figure that would contibute to the volume of what was coming out. What do you guys think it is? I have an up-pipe, turboback, CAI, and AccessECU.

 

Oh, and no engine lights.

 

Smells like gasoline. And to be honest I haven't been watching my boost gauge.

 

Could be oil or coolant.

Oil could be there due to bad turbo oil seal or pinched oil return line. Or, you could have some major engine damage, but if you don't hear anything weird, it is not major. Head gasget could also cause that.

If you head gasget is blown, you will get coolant into the combustion chambers, so it will smoke too.

What have you done recently that could have caused anything like this?

Racing? Mods? Poor gas? Over boost? Uber hot waether?

 

The cloud of smoke should have a distinctive color and smell. If it's truly white smoke, it's not gasoline.

You can check the engine oil dipstick for signs of coolant contamination. It will appear as a cloudy, light-brown discoloration compared with normal used engine oil. In severe cases, it will actually be thick to cling to surfaces like semi-hardened Jello®.

A really good garage will have a leakdown tester which can diagnose anything from a blown head gasket to a cracked cylinder head or block. Hopefully, your problem isn't this severe.

black smoke = fuel.
blue smoke = oil.
white smoke = coolant (steam).

If you don't know how to diagnose the problem and repair it, I'd get it to a dealer or other repair facility soon, since continuing to drive the vehicle may result in severe damage to the engine (depending on what it turns out to be).

how many miles on the car? Could be the rings.

 

40,000 miles. I just got my coolant flushed not last week. Smoke is definitely white. Could they have done something?

 

If it was just a coolant flush and replacement I don't think it would cause white smoke to be blown out of the exhaust. They also wouldn't have to mess with the coolant line that connects to the turbo, either.

I've got the same white smoke thing going on. However, I just get it on start up, and not all the time. I'm not really too concerned. The car still runs as strong as it always has. I've got an uppipe and TBE with intercooler hoses and Cobb AP @ Stage 2. I've got 29,000 miles on my car. I don't think any of my mods could have caused any serious problems to my car. However, I'd like to hear some more opinions.
Thanks guys.

^ that's what I have. Car seems to run fine, but it just smokes up for a little bit after starting it.

 

I don't think you need to worry, but what do I know. If she still runs strong and you aren't feeling a loss in power, it ain't no thing. If you had a blown head gasket or cracked block, I think you'd see a loss in power for real. Anybody have any other opinions?

I would worry coolant leacking into a combustion camber is not good in any quantity. Leaks only get worse with time not better.

Though if the power loss isn't there its entirely possible that somehow the turbo is dripping coolant into the exhuast pipe.

I'm not sure how you really want to approach this. I suppose you could put a leak sealant in there as a temporary fix. Also visit some tecchnical advicsory sites and see if anyone else had similiar problems and how to fix it.

 

I took it to the dealership today but for the past 2 days there's been no smoke so they couldn't tell me what's wrong. Funny thing is that I stopped at BLockbuster on my way home and it smoked 1 times when I restarted the car.
