White smoke out the tailpipe after warming up
ok, i am still being paranoid about smoking coming out the tail pipe.
When i start the car in the morning at first it does not smoke at all. After a few minutes of warming up white smoke start to come out the tail pipe and water starts to drip out the exhaust. This happens not only in the morning but after the car sits for a bit out side too. Is this normal or my headgasket could be leaking again? Recent work done: Rebuilt head, new composite headgasket, reused ARP headstuds. And i just converted to E85. |
Sorry to hear this.
Sounds like head gasket. Why didn't you use a stock head gasket? |

the E85 makes me wanna strangle kittens but yeah you have a coolant leak into the combustion chamber some where most likely the HG so GL

I just did this stupid head gasket and i really dont want to do this again if i dont really need to do it? |
Is it possibly unburnt fuel dripping out? Could be running super rich once its warmed up. How's your oil look?

Oil looks fine. |
I guess what i am going to do is sample my oil and send it to blackstone labs. I was going to do that anyway, so this will show if there is any coolant in the oil.

Does the white exhaust stop, and does it smell sweet at all? Having condensation come out of your exhaust is totally normal. If the white goes away when the car warms up then I would say everything is fine.

I am going to take a video right now and will post it. |
Does it look like this? Cause mine is just a fuel issue.
|
yeah it looks similar. Ill post the vid in a few min.
|
Does it dissipate, or is it real smokey?
|
its for sure steam not smoke.
|
This is a blown headgasket smoke. I would say your HG is fine.
YouTube - Civic smoking Blown head gasket |
Go to 2:30. Thats where the steam starts
|
So anyone thing this is a problem?
|
From what I see, I would say yes, but I would want to see what it looked like after 10 to 15 minutes of driving.
|
I will do a video after 15 min driving. So you think there is a problem?
|
Well it's very odd. It takes a while for the white smoke to come out, and then once it starts happening, it's always there, and puffs after each acceleration... quite strange. Is your turbo water cooled as well?
|
Are you actively loosing coolant? Have you driven it and had any weird coolant pressurizing issues... (bad head gasket or cracked head will pressurize the coolant system) and or push it out the pipe...(there are alot of Ifs. and's and but's there) but eventually you will have to add water back to the motor because your engine is pumping it out the tailpipe. Put some miles on it, break it in. see if it gets worse.... Whats the difference if you pull the head later knowing you have a problem, or pulling the head now not knowing you have a problem.... As we say in the car world "let it develop"
I see idle condensation..... as later in the video. you see a water puddle out the back of the pipe... and you said it goes away when the engine is warm... all the condensate is used up. Goodluck |
Thanks after a short drive. No steam or smoke
|
omg Rushin stop wasting our bandwidth lol you are being a pussy your shit is most likely fine. My vote is condensation get back to us when you have chocolate milk or presurized overflow tank.
|
Will do:-)

Ethanol can have high water absorption.
Been driving through the rain a lot? Need to check your gas cap? Ethanol, especially at higher percentages like E85, can absorb quite a bit of water (2% in E30, proportional to gas percentage above E71) before experiencing phase seperation. Although you just switched, have you observed mileage? A tank with a lot of water would give you worse mileage. If you are losing ANY coolant at all then my vote is on head gasket. The BPs tend to always have head gasket problems once they've cropped up unless it is fixed right the first time. We gave up on the original motor in my car (mom's at time) after replacing two head gaskets. The second time her bf put the TB on a tooth off and I didn't want to fuck with it, so we just replaced the motor. The second motor also started leaking coolant, and my brother drove it sans coolant until it started losing oil. I've managed to keep this motor in great shape due to a PWR radiator and some shrouding. Always look at the variables you've introduced first. 1. You've touched the head...likely there's still a problem. 2. You've switched to E85...*slight possibility you could be getting some unplanned water injection. If it's the head gasket you'll know soon enough though. It will progressively get worse, and you'll have to keep putting coolant in it. |
Thanks for good info! I am thinking its just lots of condensation. I replaced the headgasket not that long ago, the head was shaved a bit and i put a composite head gasket to make sure it seals well. The car ONLY smokes while its warming up, and does not smoke on acceleration or deceleration. I will just drive it and if it gets worse i will know its HG.

figured this is normal. Just noticed my legacy does the same thing. However after i changed my oil to 5x30 my exhaust smells like raw oil.
