Noticed some leakage below my differential and pinpointed it to the vent. I took the vent off, cleaned it out, and blew some compressed air through it. I noticed that the vent was only screwed in about halfway, with half the threads exposed. So, after I cleaned it out I screwed it tightly all the way in.
Just want to check with all the Pagoda geniuses on this site that I did the right thing and did it correctly. Thx.
