Okay, recently had my cats off for tuning purposes. Went out today and started the car to pull it into the driveway and reinstall the cats. There was no vapor for about a minute until the car started to warm up, then it started very slowly and eventually developed into this. The vapor dissipates before it even reaches the top of the garage. I am figuring it is just a lot of water vapor from being on E85 + no cats but I just wanted to see what you guys think. Fluid in the expansion tank is still pretty much at the level it has been at since I flushed the system ~6 months ago. Weather is about the coolest it has been since I took the cats off.
