Is there an update on this? I know it's almost a year old, but worth a shot. I'd like to replace my 2011 Edge sport's vent with the new SHO vent, and wondering how it comes out.

I had a look at a jiggly rear axle vent on my 07 Mustang which looks very similar to the vent on the PTU except it is threaded in and not pressed in (I removed because it was puking some oil on the axle - so I installed a turkey baster vent - Ford TSB). The old jiggly vent only allows venting out and does not allow air to come back in - so much like a check valve. So I'm betting it's the same with the PTU vent. So that might explain the sucking sound after the oil cools - it vents the pressure build up when hot, then when it cools, a vacuum is created. Next time I drain the PTU, I'll try blowing a bit of air with my air compressor ( pressure turned down) into the drain on the PTU with the plug installed and see if I can feel or hear the air venting from the PTU vent. Will update with findings.

First post here

I have a 2011 Edge Sport AWD that just started the PTU belching out the vent. Winter of 2015-16 I opened up the PTU and cleared the nasty oil as best as I could, and refilled with Valvoline 75w140 synthetic. A week ago it started belching the black grease out the vent, so I sucked about 1/2 quart out of it and replaced with the 75W140.

1. Did anyone ever figure out how to get the vent out? I'd like to clean it out as there was some pressure in the PTU when the plug came out.

2. A buddy and I are going to drill and tap the PTU on my Edge Sport and his Fusion Sport soon, is there anything we should look out for?

Thanks,
