PTU Vent Tube and TSB

[metroplex]

I was reading the TSB that mentioned SHOs made on or before 11 Dec 2013 had a different  vent system for the PTU. Mine was built 21 Dec 2013 and has a tube with a jiggle cap right by the cam cover. I saw pics of someone's PTU taken apart and it had the standard jiggle cap like on the RDU where there was no tube. My RDU puked a bit of gear oil all over the cover while my PTU was clean at 20k miles. Any ideas? Is the jiggle cap better than the tube? Do I need to keep that tube and jiggle cap clean?

A year and a half ago I had the TSB done with the new vent tube installed and it's back at the dealer now due to the PTU puking again.

Did yours originally just have the jiggle cap?

I believe so, if I recall it was a short vent tube with the same vent cap where as the new one runs up along side the motor and ends at the valve cover. Maybe this is Ford's secret auto flush for the PTU....

Does anyone have a picture of this elevated vent tube?

Thanks I saw that after an hour of reading on changing fluid but I was talking about was it's location in the engine compartment. I looked around on my 16 and couldn't find it and was thinking about using it for a ptu fill point.

You could always locate the vent on top of the ptu and follow the tube up.

I'm curious if that top portion of that vent tube is easily removable. It would be a great way to fill the ptu on the 13-up instead of dropping the DP's and using that crows foot. Anyone ever tried that method?

Not sure how easy but that's my plan for when I change mine and will try to refill from there..

my RDU constantly pukes gear oil. Was looking for a different vent without paying all that money ford wants for the relocation kit.

Please post back with whether or not it was easy or even worked. I don't see why it wouldn't. One would just have to ensure to put in as much as you take out

Another member here told me it's not hard to remove and kind of like pulling a barb off a hose. He also said make sure you grip the hose below the vent cap when removing it or you could pull the hose off the PTU. Also with that vent cap being low at the bottom of the rear valve cover I'm going to put a hose coupler and a small length of hose on it for easier filling. I will measure how much I put in and also leave the fill plug off of the side of the PTU so I do not overfill and I'll just monitor it when gear oil just starts to drain out.

Sounds like a wise member.

My crazy mind may be making this up, but I thought I recall reading that some units experienced PTU fluid leaks because the vent tubes popped off the bottom fitting.

When I was futzing with my OE vent tube, it basically fell off the PTU fitting when I grabbed the vent hose. No big deal since I was replacing the whole thing with a longer section (and a small hose clamp for good measure).

If it happens to come off while your trying to pull the Goretex cap, the nipple is directly on top of the PTU right at the vehicle centerline.

As far as I know, the only way to reattach is from under the vehicle, and it's a blind mission.
