Ever since fitting my XS mani I've noticed that the DV piston can get quite dry and stick sometimes. I've been opening the DV and applying fresh grease too it once a month to keep it nice and smooth. I was thinking about relocating the DV to the cold side of the FMIC after the map sensor, which is the common place, but I'm worried about the WMI! Will the WMI spay end up interfering with the DV? I've taken that hose off the TB before and there has been a light mist of fluid around the TB so i'm sure it'll work it's way into the DV. Is anyone running WMI with the DV on the cold side? Do you get any issues? Are there any other DV locations that would be better then the nasty hot area behind the head?
