*Newbie Q?* White smoke during decceleration?

[Shivasdaddy]

Ok well if it is, I guess I'll just have to bite the bullet on that install.

I did narrow some things down in that it only does it during quick decels for example when I'm holding the clutch and or brake without giving it time to idle down freely. When I approach a stop and just creep it does it significantly less if none at all. Some friends mentioned it might be in the tune since its e85 with an upgraded fuel system.

Here is a quick clip I uploaded for an example

I've used them several times over the years and it's a $28 diagnosis with numbers not guesses. Don't worry ahead, stay cool and deal with the issue as it arise.

Check and see if coolant levels are staying consistent also. Had the car ever overheated?

 

[Shivasdaddy]

What temps would I see for overheating? Coolant is still a hair above max same since the factory. Only 7k miles. And the peaks I've seen were 205-210 cylinder heads temps. Usually hangs around 200

Those temps are normal. If your coolant level is staying consistent you should be good there. It's a sealed system so just keep an eye on it!

Other possibilities I've experienced that may relate to your issue are:
- failing turbo seal or damaged piston ring (early stage) under acceleration engine is burning oil clean but on deceleration or idle excess oil isn't burn as clean resulting in smoking. I brought it up because you mentioned of low oil level before last oil change. This is a long shot imo
- failing head gasket, still developing
- cracked cyl head
- E85 tune? Not enough expertise in this area so I'll let others to comment on this

Hello.

If you made a switch to E85, it produces a much higher amount of water vapor in the exhaust, a fair amount more. This water will collect in the piping and come out burning off as the pipes heat up. It does not look like anything to worry about. We are here assist if you need any help, please message us or call at 505-873-4670 if you have any additional questions.

This is what I was going to suggest. E85 causes a much higher level of vapor - I get vapor condensation even in warm weather once I switched to E85.

Did that video lead you to believe it could be vapor given the current characteristics?
Also what would be the way to fix this?
Run tanks of 93 here and there?

I would just monitor it and check your coolant levels here and there. If it's just vapor there's nothing to "fix". It's normal behavior of running E85. I'll say that once my exhaust is hot and the water gets vaporized after some miles that I don't get any more visible condensation out of the pipes.
