2.7l Edge Sport oil pressure issue

[Mistro399]

Hello. New to the forum so hopefully I’m doing this correctly. Bought a used 2016 Edge Sport 2.7l with 106k miles. Great maintenance history, it’s a Canadian version now in WA state. Had it pre-inspected by mechanic and only issue found was oil pan had a small gasket leak. Mechanic replaced with Dorman OE aluminum pan. When on the freeway at 70mph I can accelerate hard and every time at 82 mph and around 5,600 rpm it cuts out suddenly, then a few seconds later the “Low Engine Oil Pressure” warning flashes for one second and then everything runs normal. No engine light, no code, and no code to clear in the system after the warning. I don’t know if it did this prior as we took it straight in to get fixed. Oil looks perfect, mechanic states oil looked perfect when he inspected pan, inlet tube, and so forth. 
Ford states it is not “limp mode” and it is not a speed or rpm limiter setting issue as that would give warnings and shut down cylinders. I see 3 Admin keys in the system but no mykey. My mechanic had it hooked up to diagnostics computer and drove it for 1/2 an hour and made it repeat the issue every time. He replaced oil pressure sending unit. No change. My mechanic states Ford should wipe out admin keys, and start fresh with factory ECM/Transmission settings. Ford said that won’t do anything.

 

 

Oil pressure maxes out at about 40 psi under hard acceleration, and mechanic states it looks to be working great so he doesn’t think it is an oil pump issue. Mechanic states he has used these oil pans on dozens of edges and never had an issue. He is stumped. Any thoughts?

Welcome.

 

If the engine cuts out it's expected that the low oil pressure light comes ON.

 

I think you should find a more qualified mechanic or consider a good Ford dealership.

 

They changed the low oil pressure switch, but maybe they should have looked at the oil pressure regulating valve?

 

I recommend using Forscan to scan for codes.

 

Post some detail on the OE oil pan.

Shouldn't it go higher? I remember at idle it it should around 20 something and it can reach 70 something on load. 

 

Edit: found a screenshot I made here before.

I thought the same thing? I thought 50-65 was normal and 70 should be fine at high rpm’s. Guess I’ll call a different dealership. Thanks!

I’m having exactly the same problem. I replaced the OEM oil pan with an aluminum one, and the issue cropped up on the highway at 170 km/h—or at around 145 km/h in "S" mode. In city and country driving, the car runs perfectly normally—just as zippy and agile as ever. It just doesn't like high speeds anymore. I’ve ordered an oil pressure sensor and a new oil filter. If that doesn't work, would I have to switch back to the plastic pan?

[Samurai Edge]

Mistro399:  Did you ever solve this problem?

 

To both Mistro399 and Cossie:

You didn't state under what conditions the engine shut off has occurred.  Were you driving in a straight line or taking corners when this issue rises?

 

I have no idea what specific aluminum pan you are both referring to but it sounds like a possible  oil starvation issue.

Not knowing the specific internal design of the aluminum pan vs the OEM pan leaves a big unknown.

Just because something will fit does not necessarily make it a good choice.

Also, as the design changed between 2015-2017 compared to newer models, does it have the correct check valve for the PCV.

Hello Samurai Edge, 

I’ve been getting this error message on my Sport (2.7L, 108k) ever since I installed the aluminum oil pan. The vehicle doesn't shut off; it just briefly throttles the speed and continues driving normally, though it won't go faster than 170 km/h. My car has had its speed limiter removed; previously, it was capped at 211 km/h -2018 Import to Germany. After the unlock in 2019, I did a test run up to 244 km/h—which was fast enough for me. I first noticed the issue during an overtaking maneuver that I couldn't complete because the car slowed me down. Up to 170 km/h, the car drives completely normally. In Sport mode (S), the error kicks in earlier (at 145 km/h) than in Drive mode (D). The plastic oil pan was replaced, and I suspect the issue lies with the intake pipe in the center of the pan. The plastic version has a wider oil inlet there, whereas the aluminum pan has very little clearance milled out around the pickup pipe. I don't know for sure if that's the reason, though.

This looks like your oil pan:

What I am not seeing / finding is an oil pan pick-up anywhere I look.

 

That could be the problem right there.  The oil pick-up, being smaller on the aluminum pan sounds like the culprit.

A smaller than designed oil pick-up could create an oil starvation issue, but that's my thought.

 

When you look at the oil pick-up area on the OEM pan, it looks like that white " plastic cover " creates a larger area for the oil to gather for pick-up into the motor.

The aluminum pan has no such area but pick up directly from the open pan area.

A typical oil pick-up has section at the end of the pick-up tube that sits bathed in the oil to suck in the oil in the pan.

I think the OEM white " plastic cover " is that section I described above which is clearly missing from the aluminum pan.

 

Presuming you didn't change anything else, looks like you know your issue.

I am not able to see what it picks up. The hole seems closed off and as if it can't suck any oil!!

Also, as there is an oil pressure sensor, the engine output is probably being cut when pressure is dropping. And on S being earlier is probably because it doesn't upshift to 6th and engine speed is staying at a higher RPM longer compared to D where it would upshift to 6th. 

[Cossie]

Thanks for your Answer, 

That’s what I suspect, too. The design of the intake pipe cover allows more engine oil to accumulate, ensuring it gets drawn in. In the aluminum pan, there is likely too much turbulence at speed, which hinders the intake process. So, I’ll probably have to buy a plastic pan—if I can still find one. My search has revealed that none of the spare parts suppliers in the USA ship to Germany.

[Cossie]

Omar302,

"The opening appears to be sealed" – no, it is a wide gap, roughly 1 cm high and 6–7 cm wide, allowing the oil to flow in. This means the oil at the bottom is shielded from the flow occurring above the intake pipe.

The higher engine speed in S mode makes sense, as more oil is being pumped, meaning there is insufficient oil available at the bottom for a brief period.

And, as Samurai Edge also suspects, the missing cover in the aluminum sump is likely the cause of the issue.

[1004ron]

@Cossie you could attempt to make a similar "baffle" from aluminum replication the white plastic one seen on the original pan.

 

Also, what about running with a slightly higher oil level, like an additional 500ml?

 

Are you using the original dipstick?

You could use a drop shipping company.

I was wondering if there was something like that.  Good idea!  💡

[garycrist]

Pull the pan and cut a new slot in the rear of the pick-up. At the very least debur the entry hole and hog it out to

make up for the volume loss due to a smaller feed hole diameter in the Al pan.

[Cossie]

@1004ron  One could test this by setting the oil level slightly above the maximum mark. It is the OEM dipstick.

[Cossie]

@garychrist

 

That would also be a way to keep more oil in reserve. It should be stable enough, given the thickness of the material. I’ll need to discuss this with my workshop—and also whether a cover should be fitted over the opening, similar to the plastic pan. I’ve also found a dealer who ships to Germany. Surely others must encounter this same issue with the aluminum oil pan when they perform an oil change and then drive at higher speeds? In Germany, some stretches of the autobahn have no speed limit—whenever traffic conditions allow for it, at least.

I don't think this would solve the issue.  One would think it would not hurt.  You would still be missing the point of the white plastic baffle which is to hold a quantity of oil in a specific area of the oil pick up.

 

Which raises another question:

I could not find an oil pick-up tube in the parts drawings anywhere for this particular pan.  Does this connect directly to a port on the bottom of the engine or is there indeed an oil pick-up tube?

If there is indeed a pick-up tube, then there is another possibility that there is a loose connection of the pick-up tube to the motor  OR  that pick-up tube may be cracked, leading to a loss of pressure especially under high flow, like hard acceleration.

I would guard against this.  Even if he took the actual white plastic baffle and went to install it in the aluminum pan, the only apparent way to attach the baffle would be to screw it to the pan.  The pans are not that thick so that would most likely crack the pan or cause an additional point of leakage.

 

Another possibility would be something like JB Weld, but I don't know how such a product would last being submersed in oil, even hot oil, in it's lifetime.

From the photos of the oil pump, it doesn't seem there is any such tube. Only a gasket in the pump that should go over the pick up tube.

Link to the oil pump. 

[Cossie]

The idea is interesting; a similar "baffle plate" made of aluminum could be bolted around the oil pickup—which is made of thick material. It would only need to be a few millimeters long so that it doesn't protrude into the oil passage, or it could be secured on the outside using a pipe clamp. Perhaps I’ll look into installing the plastic oil pan during the next oil change. If the car ends up driving fast again, it will simply be due to the cover over the oil pickup.

[garycrist]

Pull the pan, weld 2 locator studs and use the old plastic pick-up.

Be sure to measure pan to oil pump for fitment.

Also Moroso Coyote Gen3 might be a thought for "raw" material to engineer a pick-up.

(Moroso catalog page number 18)

 

Looking at the pics of the 2 pans and estimating PU IDs the plastic PU ID (inner diameter) I

guestimate it to be .9 inches while the Al PU looks to be about .75 ID.While the slot Looks

to be .75X.75

MATH for area of openings. All measurements are by guesstimation based on the pics supplied above.

Formula for area of circle Pi RXR.

Formula for Al pan PU LXH

Stock .9X.9X 3.14=2.54 SQ inches.

 

Al Pan .75x.75 x3.14=1.77 SQ inches

 

Slot for oil pickup .75x.75=.5625 SQ inches

Even if the slot was 1 inch wide and 1 inch tall, one still can't pull enough oil. 

 

Also I do not think one can separate the stock plastic pick-up from the pan.
