No, of all the things that Ethanol is demonized for... it won't make your gaskets leak in normal use. It doesn't even directly touch any oil wetted ones and should be able to be handled normally with pcv consumtion of vapors in any normal, modern system.

These types of things make ALOT MORE OF A DIFFERENCE !!
