I was going to use the hole in the front closer to the carb base plate, which is baffled. However, the grommet that came with the PCV wont seal all the way. The cut outs for the twist in hole would still be exposed. I was thinking finding a grommet that would seal the cut outs (1/8-1/4" larger) and just using a filler cap on the hole that does not have a baffle.
