Warning low oil pressure!

Anybody with a 2nd gen been greeted with this message in the dash?
On the way to work this morning in the Expedition 60mph or so, on hwy, 10 minutes, suddenly greeted with this message.
Made it to work, a few minutes later, no odd sounds. Turned it off, checked under hood, saw nothing. Moved to truck to a level surface, about 30 minutes after arrival, and had pressure again, until I put it in reverse to back into new spot, then message came back.

Thinking something might be in the oil pan????

A weee bit bummed, it has manifested itself at 3700 miles, thought by now I'd be in the clear.

I have not had that issue... Please keep us posted on the outcome.

Do you have a 2nd generation Expedition, or a 2018 model?

Basics: Correct oil level, and correct viscosity? Correct (not, cheap aftermarket) oil filter?

Time to see the dealer if under warranty.

This is pic right after I hit ok, to make msg go away.
Going to change oil and filter before leaving work, hopeful that contamination comes out with oil. Really don't want to go to dealer. Also don't want to pull the oil pan, but if a simple oil change doesn't flush it out, it's my next option.

It's been right at 3000 miles since I last changed it, I feel it's due. The service manual also concurs that under severe duty oil should be changed ~3,000-3500 miles. Should have done it over the 4 day mini-vacation!
FML.

2nd gen Ecoboost.
Motorcraft filter and Motorcraft oil changed at 600 miles.
I'm cheap, but not to the point of stupidity, though some may think otherwise, taking it regularly to the Dragstrip, LOL.

There is a pulse width controlled solenoid that controls oil pressure
Might have that checked
Always use motorcraft full synthetic & OEM filters in mine as well
Have 9000 miles on my EXPY with no issues

Check for any crank case excess blow by with the cap off while running. The indicator coming on makes me lean to low level of oil. This could be cause from a few things. Check your coolant, oil level, and exhaust pipe for any oil residue.

The XLT instrument cluster is a little different from the Platinum. I thought they would be the same.

 

[Mike Wolfe]

Here is the location of the oil pressure control solenoid
Doubt you have anything major going on
Possibly solenoid stuck open from small particle

Please explain what you define as major?

My recommendation to you 5150 is start making sure your service records are air tight. All it takes is a split second of pressure loss to cause valve, bearing, or cylinder/ ring issues.

This pressure issue isn't new to Ford, and if major repair/ replace is required they do fight.

Coolant is fine.

Reading up on a few other places I came across this thread I'll post at the end. It sounds exactly like my circumstance, except I wasn't hot dogging it on the way to work. It was raining.

I'm thinking it was brought on by oil degradation, once the engine was up to temp, the viscosity went away.
First and only oil change I used the motorcraft blend, with the intention of using Mobile 1 at 4000 miles.
I'm going to do the change at work, once I'm done with the day, fingers crossed.

Also ran across a thread about Puralator oil filters making Motorcraft filters and the Puralator version having had a bad batch that may have extended to the Motorcraft branded version, element separating blocking oil gallies, etc.

So in with the Mobil1 or Bosch oil filter too.
Will also send sample of old oil to Blackstone, for analysis.

Where was the oil on the dipstick? Reading that thread you posted, seemed to indicate that the oil stick isn't accurate, you should be at least to the full line and maybe slightly over.

Oil pressure light coming on when changing into gear smacks of low pressure when revs drop which can happen if intake pipe assemble is just at the oil level and is starting to suck air as well. Think noisy straw at the end of drinking a glass of pop.

MY experience has been that these engines are very durable so I doubt it is anything major
Possible just the connector to the oil pressure control solenoid
Of the six 3.5L ECOBOOST engines I have owned, always changed the oil at 5000 mile intervals
Always used full synthetic oil & OEM filters (have all my oil changes done at the dealer because free oil changes for life is part of the purchase deal)
None of them used enough oil to see a difference on the dipstick between changes
Always right at the full mark
Never had any mechanical issues with any of them
All of them tuned with 93 octane tunes within a few hundred miles of purchase
Always used 91-93 octane premium fuel in them when I could not get & mix E85 with premium

Sat all day, on level ground, I had a bit of a pitch where I normally park, so to be sure I moved it after I thought about it.

This is the stick.

Assuming this is your oil level



Then we've ruled that out

Looks pretty clean as well

 

[Mike Wolfe]

Thought all of you might this interesting
Here is a pic of a Ford ECOBOOST piston


Note that they use a forged piston with a steel ring land for the top compression ring just like those used in Diesels
The also use deep skirt blocks with cross bolted mains, forged crankshafts & forged connecting rods
Makes them pretty bullet proof

That's pretty stout stuff Mike. If it happens again be sure you snap plenty of pics from your phone, showing the dash low oil pressure, along with pics of dipstick level. When it comes to dealers you've got to prove your case. You might want to do an oil pressure test yourself, or maybe pay a shop. Just again for ammo, in case you have problems down the road. As far as oil filter, you might want to try a top filter besides Ford, if in fact their having breakdown of paper in filter. Ford racing filters, along with Mobil 1, and Royal purple are the 3 top ones out there. Not cheap, but do work well.

Might should add "almost" to that last statement.

Still no word from the almighty.
I'd say the oil level is actually a bit right of the center of arrow.

Sloshed Mobil 1 oil and Mobil 1 filter in it, made zero difference. Cycled ignition numerous times, on the way to dealer, before I realized "dummy clear the code on your phone".
That is the weird...clear code as soon as it triggers, immediately would show regular pressure in dash, then it would lose pressure on gauge, repeat.

Surprised it still ran, to be honest.

Well Pops
Did you get trouble code P0521, 522, 523 or 524?
If it runs with no knocks then it has to electrical issue
Has to have oil pressure or engine would have seized by now
BTW if engine actually has no oil pressure I am pretty sure PCM would shut down engine
have you looked to if see you might have accidentally loosened the connector for the oil pressure solenoid when you installed the CAC?
It is to the right of the harmonic balancer (passenger side)
How about the EOP sensor connector directly above the oil filter?
