Since e85 is hygroscopic, will it cause white smoke after sitting 4 months?

Seems like there is a little more to unpack here. The short answer is yes, IF a large amount of condensation built up in the tank over those 4 months. Was the car smoking previously? A quick test to see if there’s water in the E85 is to take a known amount from the tank (10mL) and then get some gasoline and mix the two together. If there is separation between the two when you mix it then you have water in your E85. If not, it could be the E85 tune. I hope this helps.Since e85 is hygroscopic, will it cause white smoke after sitting 4 months?

Keep us posted. I’m interested to hear what the results are. Good luck!Good point. Never smoked before but this is a fresh built short block. I’m going to drain the coolant and start it to see if it still smokes. That should tell me if it’s coolant or fuel
I’m betting it’s water in the Fuel. Hoping for an easy fix for you.I will be buying jugs and emptying the tank. Will update this post afterwards. Thanks all
Thank you for correcting me .. I can see how that may happen ..@Widgmaster a engine can suck in brake fluid. I had diaged a car that came in last week that was stalling and eating brake fluid like no tomorrow. The seal on the brake master was really bad and filling up the booster with fluid. But I will say I've never seen white smoke from brake fluid.
What does it smell like? it kind of looks like steam to me.
Drain the water and see if it still smokes.
Depending on temp my car when warming will sometimes smoke a light white till warm. This is on e85 tested at 85% and it goes away once car warms up. There is zero smell to it.
Does it keep getting worse as the car warms up ?
around where i live most of the e85 is really like e68 i run it in my sti. depnding on the weather the exhaust has a (steam) look to it. yours doesnt look to bad. im iterested in how this turns out.
Just looking at the video, you're idling at ~11.8 A/F, bet that is why you are smelling e85 at idle haha But it does look like steam to me as well as it disappears as soon as it gets passed the garage door. If it is white smoke, it would carry further before disappearing.
I ran into a similar issue and it was an issue with venting the crank case i tried using a closed catch can. Changed back to the JAZ filter top and it went away. Just a thought.
