Got the call this afternoon that the Edge is done and ready to be picked up.  Both the transmission tech and service advisor drove it and confirmed it is fixed.  I will pick it up tomorrow morning on the way home from work.  Fingers crossed everything is good now.  I have some projects to finish on it now.

I wouldn't say the lube totally cured it, but it helped a great deal.  I recently had the brakes done (pads, rotors, both axles) and when I got it back the low speed squeaking started - so I suspected they had not lubed the slides or pad surfaces well enough or at all.  I went back on this trip and had a can of purple ceramic permatex ready to use on the steering wheel.  They did (I can see it) and I am convinced it helped a bunch.     Now, I get a very slight squeak for just a second or two when slowing starting out - disappears at speeds above 5-10 mph.

Extensive cleaning is the norm when it comes to gaskets.  I remember when they used to use a shellac as a sealant for the gasket on metal pans or anything else under the hood where two parts needed to be joined.  If you wanted the new gasket to seal correctly, it was a pain getting the old shellac off.   Most likely repeated leaks after service was due to the Tech, or the individual, not properly cleaning the area before re-sealing.  It takes effort.  Not a 5-minute job.   When both are available, I use both a gasket and an RTV sealant.  A gasket helps to prevent over tightening the pan bolts and squeezing out all the sealant. When no gasket is available ( or also with a gasket ) I have found the Perma-Tex Gray sealant to work really well with oil, or other liquids, like coolant.  You just have to let the sealant cure enough to a " semi-solid " (?) before merging two pieces together.

The issue used to be because the original pan and even several OEM updated versions depended on RTV gaskets that required extensive cleaning from possible contaminants and long cure/drying time that would eventually leak. Making an official fix unreliable.  Ford later did come up with a Oil Pan with a press in gasket (instead of the RTV), so the official (latest) fix should be a good one with no need to look aftermarket, in my opinion.    The fix differs between  model years, for the 2015-2017 models is under TSB 24-2345 (link to details). 

Ten extra HP doesn't really amount to much.   One just has to remember if they are comparing apples to apples. In this case, as long as the numbers from Ford were from a dyno, and not advertised numbers you see in the brochures, then they are a little more comparable.   If one is using the same vehicle, on the same dyno, on the same day, at the same time of day, by the same operator, using fuel from the same source, then the numbers would be directly comparable.   There area lot of variables to consider when attempting to compare dyno numbers.  People always don't understand this.   The other thing to remember is that if you are comparing advertised numbers to dyno numbers, as opposed to actual dyno numbers, there is a parasitic drivetrain power loss between the motor and the wheels.

All the work required by someone who knows what they are doing would not be cheap.  Then, hopefully, there would be zero leaks but it would be something you need to be aware of as a possibility. This is custom work and the new installed, fabricated baffle would have to be test fitted to ensure there is proper clearance.   -  This is where trial and error come in.  Been there.  Done That.   -  On a different vehicle years ago, I had an oil starvation problem on high speed turns.  I had the oil pan modified with extra side baffles and an extension to keep the oil down in the pan.   To me, unless there is a failure of the plastic pan,  AND  if a proper OTS aluminum pan existed, only then would I consider such a plan.   If the only issue is a leaky gasket, I would just properly replace the gasket.   Unless, of course, your plan is to race the vehicle, then we are talking a different situation.

I found a thread in Facebook of a similar issue. Seems the common issue is the aluminum oil pan.    https://www.facebook.com/groups/fordedgeforum/posts/2749362808595155/

I am having brake squeaks (groans?) at very slow speeds, like when trying to creep or at the end of brake just when coming to a complete stop or when releasing the brakes slowly. I was thinking that the slide pins needed lubrication as I don't recall my mechanic doing so.  Did the lubing cure the noises for you?

@garychrist   Two positioning pins would need to be welded on, and small threads would have to be cut into the weld points on the original plastic suction pipe to allow it to be pressed down and secured. The plastic ribs within the plastic sump are sealed off, effectively using what look like plastic plugs. Many thanks for calculating the dimensions; I’ve taken some photos, though I don’t own a set of calipers, and my flexible ruler has rounded edges.   <<Furthermore, I don’t believe the original plastic suction pipe can be separated from the oil pan.<< You would have to cut off the connecting studs to remove the cover, but reattaching it to the aluminum oil pan would be a real piece of custom fabrication work. For now, I’ll keep driving the car as is throughout the winter; when the oil change comes around in 2027, I’ll have to come up with a solution with my mechanic. Due to the way they were manufactured, all EDGE models equipped with this aluminum oil pan—and whose owners want to (or are permitted to) drive at high speeds—are affected.   Yesterday, I drove 190 km on the motorway, never exceeding 155 km/h. It’s doable, sure... but it’s much more enjoyable when you don’t have to constantly keep an eye on the speedometer needle 😉 and the acceleration remains absolutely "fantastic."

My Dad is 84 years old, and he is a phone zombie. He constantly complains about how his phone screen is too small to see everything. I told him that's because the screen is so small you are limited to what you can see and explained to him the whole reason apps were developed; so people could replace their lives for their phones. He agreed and we had a good laugh. I showed him how much more screen you get by using a laptop for internet browsing etc. He could not believe the difference. Apps were designed for phones; Nothing better than getting the full benefits by using what works best. Other than this forum, I am not a social media zombie. But I am glad to have this forum to get valuable information, All the pop ups suck, but I got used to them.
