There's another thing that has come up when using E85, a lot more poo in the oil overflow tank. Looks like you have to change it very regularly. I think I'm going to route mine directly into the exhaust to take care of this.
Pardon my ignorance, but where is this oil overflow? Do you just mean catch can?
