Turbo leak-----Nope---New PTU

[bpd1151]

I swap my PTU fluid twice a year.

Regardless of miles accrued.

Once in Spring. Once in Fall.

I'm actually seriously contemplating drilling / tapping the housing, to install my own drain hole to make performing this service, a lil less of a headache.

bpd... when you service it at the intervals you use is the oil liquid enough to evacuate?... The ones Pictured here that failed looked like they were full of tar.  Do you pump the fluid out? ... and does it still flow and look like oil?

 

[bpd1151]

Never like oil, but not anywhere near the paste like sludge pictured in this thread.

Suck it out with a pump & the viscosity appears like ummm..... what comes to mind..... like ketchup perhaps?

On the verge of turning thick, but certainly some degree of fluidity left in it.

Not sure if that makes sense? :dunno:

Thanks... Good info that helps to get it to make sense.  :thumb:

Haha! Wow. Ketchup.

What are you filling back into it?
I feel like there's some room for improvement, possibly with just upgrading gear oil.
Perhaps one that is better suited or tolerated for excessive heat and heat cycles...

It looks like this will be next on my list. I may have to visit BITOG to see which available oils are most heat resistant.

Thanks to Livernois for sending tunes with the new Strategy codes so quickly.

is there a how to change the PTU oil, and a reccomended replacement oil ? Is it worth doing at home, or take tot he dealer ? I'm at 24k miles.

That is the problem . No OEM recommendations on this at all .
There is a post about installing a drain plug on the forum somewhere .
I need to find it , otherwise it needs to be siphoned out .

Are you referring to the writeup by the_natrix on the Edge forum?  http://www.fordedgeforum.com/topic/10914-ptu-leak-failures/#entry89270

I think crash got his info from there. .... good stuff though.

It looks like the 2013+ PTU has a drain plug , I'll have to check...

I also believe I can rig I PTU cooler for as well. However for straight line drag racing it my not be entirely necessary. With a brief engagement.


I found this pick a while ago for how to add I drain plug to PTU, I figure with that and the fill plug up top and a rear dif cooler system. You'd have a cooled PTU.
But I think a 2013 pp PTU retro fit is entirely do able. Just a lot of $$$$'s

  I think that between 25k and 30k between changes is a good number. I go to the track 2 to 3 times a season and during the times Ive changed it, by 30k its blackened right out.  More than that it turns into a thick grey paste.  My first two changes I vacuumed the old stuff out.  Now with closer intervals I use a manual gear oil pump and "flush out" the dark fluid until it runs clear.

Corrected link to the other forum.

We do need to verify what updates over the 2010-12 model PTU's the 13+ might have.  If they have a drain plug, great, and if they have aux cooling, icing on the cake.  If someone knows for sure, please post up supportive images/documentation.  TIA.

Interesting find on PTU on Police  interceptor version and some middle eastern PTU's that are WATER Cooled :

From what I've heard, the PTU lube is an all or nothing type of thing. It might last the lifetime of the vehicle, but if it goes overtemp just once, it's junk.

Now the statement in the MKX manual is likely targeted to the Middle East crowd, they do a lot of sand driving over there. In fact the Explorer sold in the Middle East has a water cooled PTU. But if you look up the Police Interceptor OG, it describes how the Police cars actually have an "active" monitor that basically looks for overtemp conditions and if it sees them, it puts a notice to change the PTU oil in the message center.
My limited experience has been that in normal on-road driving, you're never going to overtemp the fluid, thus a lifetime fill is reasonable. But anyone towing on hills (especially twisty hills), going to a race track or doing a lot of aggressive off-road or snow driving could get to the point where the fluid needs to be changed.

2013+ PP pkg SHO's do have the auxiliary water cooled PTU.

Lots of work to retrofit from what I understand.

Yea ... But would it be worth it ? . Any idea if the  13+ PP has a drain plug or the if the non PP 13+ has one ?

 

[bpd1151]

I don't know on the drain plug,  but i do recall somewhere, a person having posted an image of what appeared to be a drain plug, located in/on the housing assembly of the PTU.

I saw the image, & it did appear factory.

Non PP SHO's, for 2013+ do not have the auxiliary coolers.

I.E. Auxiliary Oil, Trans, & I stand corrected......

I misspoke...... the auxiliary cooler goes to the rear diff IIRC, not the PTU as I previously advised.

I'm at work at the moment & don't have the ability to double check schematics.

Perhaps someone else can chime in, in the interim.
