Can fumoto valve cause oil pressure issue like dealer claimed?

[keny01998]

I got my 2019 Expedition back after the dealer replaced the cam phasers, vct unit. On the ticket, they said aftermarket fumoto valve for the oil drain plug cause the oil pressure issue as well as tight oil filter. So they removed the fumoto valve and replaced it with regular drain plug. The Expedtion does not have rattle now. Let hope it stays that way.

How could a oil drain release valve cause oil pressure problem?

How?? It's a plug? When closed, it performs the same as a regular drain plug...

Neither the valve nor the "tight oil filter" makes any sense to me. And if a tight filter causes issues then Ford is their own worst enemy because I just did my break-in oil change on my '21 and I had to really struggle to get the FoMoCo filter off.

Just out of curiosity, what brand of filter did you have on there at the time of the phaser swap? I had a phaser issue with my '05 many years ago and the dealer tried to say it was caused by aftermarket oil filters starving the engine for oil.

You must use an oil filter with a backflow valve, such as Motorcraft's. Filters that permit oil to flow back down after the engine's turned off will eventually cause damage. A "quick drain" oil pan valve can't possible cause any ill effect unless it's ripped off by road debris or leaks.

No and No. As another person stated, now arguably if the Fumoto valve leaked, then one could say it would cause a problem, but if it's not leaking, its doing the same thing as a plug. I had a Fumoto valve on mine when it went in for the phaser fix and they didn't say anything about it.

They sure did note on my work order that I had "an extra aftermarket wire for exterior lighting". And as for the oil filter, too tight can cause issues but it would get real sticky for a mfr to claim that only their brand could be used. I often wonder if Ford dealers put notes like this in their WO's to give Ford or them an out later, something to blame future issues on, legit or not.

Many quality brand oil filters have anti-backflow valves in them. It's good practice to use them. Otherwise there's some oil starvation on cold starts that denies the chain tensioners proper pressure and the chains rattle until pressure builds. That's not good in the long run as the chain guides are plastic and they'll wear faster with the chains running on them at startup.

That is the Best one I heard of in along time!!!!!!!!!!!!Guess you must have to use approved washer fluid Or void your warranty.

I found the ticket and here is the exact words:

CS there is a loud rattle on start up in the morning. 21850 verified concern, found vct rattle on start up vehicle will need TSB 21-2119 applied. Remove and replace VCT units per TSB. Performed neutral profile relearn, tested concern no longer present. Vehicle had after market oil drain valve installed that did not allow for proper drainage of oil pan and may cause oil pressure. Oil filter was on way too tight. Improper tightening of oil filter can lead to over compression of oil filter gasket, loss of oil pressure and engine damage.

I also use Mobil 1 212A and Penzoil Synthetic 5w30, changed oil every 5k miles. The oil change was a mess that why I got the Fumoto valve.

 

[Trainmaster]

That's pretty crazy. Why not send a copy of the bill to Ford's corporate offices for further explanation? Probably get a form letter warning about "aftermarket modifications" but might be worth a try.

No, I've used one on my F150 for years, no issues. I plan to get one for my wife's expedition once the reward points run out and I have to start paying for oil changes.

I would argue the fumoto valve is better for the engine, many incompetent people just lay the oil plug on the ground or on a dirty parts/tools cart while doing work, and then forget to clean it well, meaning you're actually introducing contaminates right back into the system you just cleaned. A valve that really only allows for one way flow and isn't removed is cleaner, so take that Ford! Or something like that.

Did they give you your Fumoto valve after they removed it?

Maybe it was kept for evidence.

 

[Trainmaster]

Nutty stuff.

I had a dealer try to tell me that attempting to read an error code caused the error condition. Guess my code reader was a DeLorean and we pulled the code traveling 88mph.

I have no idea how warranty compensation works for the local dealers. But it's my suspicion that they get more money for non-warranty work. So anything they can do to attempt to get you to pay out of pocket may be attempted.

The only thing I can think of about the Fumoto valve is that depending on the length of the part that threads into the oil pan, it won’t allow all of the oil and other contaminants to drain out. And then those contaminants go on to clog stuff up. Versus a normal plug that you pull out that might lower the effective height that the oil needs to be at to drain all the way.

But I don’t know anything about the Fumoto so this could be wrong.

 

[keny01998]

Yes, they gave me back the Fumoto valve

While this is sound logic I would have to think once the new oil is added whatever was still in the pan would be diluted enough to circulate through the engine allowing the filter and catch any contaminates. Unless we’re talking large enough particles that they get trapped in the oil pump pickup screen… if this is the case then the fumoto valve is the least of your worries.

Guys, I think my Expedition may have another issue after the cam phaser replacement. I'm on a vacation to Florida and after a drive over 2 hours, I saw white smoke coming out from the hood near front passenger side with rubber smell. Is that normal?

I pulled over and check coolant level, it's still good but as long as I started driving, I saw smoke again. The transmission temp is around 214-218. Of course Ford dealer closes on Sunday, I need to to check if anyone has ideas.

No, definitely not normal. I would take it to a dealership to let them look at it. What's the engine temp when it's doing this?
