I'd be willing to say...from what the underside of the aircleaner used to look like (well oiled) when I used to use that hose as a pcv system...that this steam is ....vaporized oil. I thought that pumping vaporized oil through my intake was not the best policy in general and slapped a breather on there. The breather seems to have a draft side of it cause it has a brown triagular stain on one side of the drum looking breather.
It's gotten worse since I've been running 3k rpms for longer periods of time with my 4.56's.
