The short stock plastic vent hose often winds up dumping any collected stuff etc in front of the right rear tire. Many fastidious owners tap the hole for a right angle dash-4 AN fitting and run a ss hard line straight back to the center-rear of the transaxle. If you have a small lathe, you could cut the threads off such an AN fitting and lightly press it in the existing hole. Or, route a longer plastic hose to the same area. There's zero pressure in the cases so AN fittings & lines are enormous overkill, however 'racecar' they may appear.
