05 F150 5.4 3V Phasers

Did you replaced the oil pump with the upgraded meiling 360hv? I’ve seen big differences between stock one and the 360hv fixing a lot of rattling even on Chinese new phasers it is important you do if you haven’t changed the pump

I haven’t but I will tomorrow. Thanx

I would hook up a oil gauge and see what the oil pressure is. When the guides break its not uncommon for them to plug up the oil screen on the pickup tube, restricting oil flow. Also check the cam phaser actuator solenoid for plugged screens, or the housing that it goes into for restrictions. You can try to see the oil pickup tube screen through the oil drain plug with an inspection camera.

Solenoids are new. They came new in the last 3 timing kits. I’ll look at screen tomorrow. Thanx

I’m not at my computer to look up that code but it’s a circuit code so makes me wonder if there isn’t an electrical issue causing the failure. If I was Bernie Thompson I’d probably be scoping the actuator command vs the cam sensor signals to see if or where there is a breakdown. Also as mentioned checking oil pressure. also I’m sure you know but there have been many issues with some aftermarket…

I did the key on engine off code check using noid light and verified on demand signal to solenoid. Gonna check oil pressure in the morning. I know the instrument cluster gauge shows oil pressure but not sure how much. And 1st timing kit was eBay 2nd was Napa 3rd was an oem parts direct supplier. All 3 failed within the first hour.

Using a noid light is only a partial test. There is no oil pressure gauge on that vehicle, only a needle indicator which is controlled by a basic switch. IIRC, the switch state changes around 5-8 psi. You also referred to separate issues, mechanical and electrical. A mechanical fault of any timing component will not cause a circuit code, unless massive failure destroys a CMP or CKP sensor.

What is the HOT running oil pressure @ 500-700rpm? If 22 psi or lower replace the engine. This is called the "ford death rattle". It plagues most 03 to 07 f150s with the 5.4. I learned it from having a ford mechanic mentor. He was always told that its best to just replace the engine once it starts.

When i get these in the very first step you need to do is do a oil pressure check when hot at idle. There are specs but as William stated 22 psi should be there. At one time ford was saying minimum spec was 15 psi hot idle. However i always like to see 20 or above. Also i always change out the oil pump to the melling hv and switch it over to 5w30 and on the timing kit only use ford parts. I have…

2 times now, I have found a piece of debris in the small housing behind the phaser. The debris partially clogged an oil port and caused all types of timing issues. Since you're going in again, remove the plate and make sure there is nothing in the cavity behind it.

You posted a circuit fault for bank 2 cam solenoid. If that is actually true and the fault returns you must fix that first. If the solenoid is not properly controlling the oil flow to the phaser due to the circuit fault then there will be rattling an performance issues. These solenoids have IGN power on one side and PWM ground side control by PCM on the other. After fixing the fault if you still…

If you disconnect the actuator solenoids and the rattles do not come back, it is more likely an oil volume problem. If you haven't replaced the actuators, the one giving problems could be worn on the hydraulic valve side and leaks off too much to keep the phaser timed properly. I will change out the oil pump to the Melling 340HV every time I do chains on those engines. You do not have to remove…

Are you using original phasers? I’ve seen this happen with aftermarket phasers.

I wonder what you actually mean when you say “destroying the driver side phaser”? My own experience with aftermarket phasers has been very good. I am not sure what the big complaint is. Just saying they do not work is not a great way to understand why.

Hi Anthony, These are critical about having enough oil pressure and use only Ford phasers. These engines were not one of Ford's better ideas, but people bought into the advertising like moths to a flame. For many of these, I have disabled the phasers and installed timing pucks to lock the cam phasers. This basically converts the engine to a conventional fixed timing and it will run fine on…

There are kits that include a tuner that are CARB legal and should satisfy an area that has emissions testing requirements. livernoismotorsports​.​com/product/LPP822…

I may get hammered for this, if was me, I would install a phaser delete kit in it and be done with it. I've done many of these kits, and they are CARB approved. Search ebay and youtube to get an idea what is involved.

Phaser delete!!

So confused by these responses. While all the info here is correct, he has a solenoid circuit fault. Not sure how we can help until that is fixed

Hi Caleb, These Ford oil pressure solenoid operated timing systems just get worse with age. So, doing a phaser delete kit and disabling the solenoids and adding a tuner has proven to be a very reliable repair. This effectively disables the variable timing operations both electronically and physically. From my experience, engine power and reliability are increased. These systems never produced…

Please provide an example of this “miracle mileage” advertisement.

You need to understand fads. Delete/cancel is currently a fad.

Do you think that code is absolutely responsible for the rough running or explains whatever destroying the left phaser means? Probably if he was to try it with the actuators disconnected he may learn something.

Like I said in my first post. The circuit fault needs fixed before anything else is done. Im not saying that will fix it. But the guy says he has put 3 drivers side phasers in it. Seems like there may be another issue is all Im saying. Also as I said in the first post that everyones info is correct about this engine. I just think its a leading him astray until he fixes circuit fault.

Caleb, I do not doubt the fault is a problem but what he describes sounds more complicated. Maybe not? Nevertheless, if he just disconnects and his phasers stay parked at home he won't need to pull it apart to change phasers..

Hi David, Good point, disconnecting the actuators would allow the phaser to stay in the “home” position and the engine should run fine. If it is still having noise and issues, it has a mechanical failure of the timing phaser.

Anthony, I agree with the cam phaser delete 100% especially on a older vehicle like you have I've done 40 or 50 of them without not one failure. And I can do them for a whole lot cheaper than seven or eight hundred dollars we're talkin about $300 tops maybe not that much just mail me back if you want me to look up my information and I'll tell you what you need to do and it all starts with our…

Hi Alan, Glad to hear you chime in. I recall you have worked many of these. Hopefully, Anthony kept the original Ford phasers so they can be modified with the lock out pucks, that would make it nuch easier for him. Anthony, there is a You Tube channel by Fordmakuloco. This technician has many videos performing phase elimination procedures and lots of great repairs on these 3 valve Fords.

Glenn, I have had some customers in in the past and according to the customer the vehicles have been repaired previously with new sprockets chains and guides the works. We would pull the valve covers first and every time the sprocket had failed and had Dorman wrote all over it. The OEM gears rarely fail. To save the customer money I will go to Pull-A-Part or U-Pull-It find a good clean engine…

new phasers, tensioners, cams, chain and guides. Also oil pump hv Mel longs and all previously mentioned parts from Ford dealership. Truck ran ok for about an hour. No codes, no rattle. This morning it’s back at my shop with failed phasers :(

Anthony, Exactly what part of the phaser is damaged. I would love to see some photos if you can post a few showing the damage. I think it's a Oil related issue causing it .I've seen it before and it's always on the driver side but if you totally eliminated the movement of the variable timing it cannot damage it any longer. If it was a 2022 Ford F150 I would have to say we need to research and…

Let me try to download the phasers pics but the pin that goes into the slot of cam was shearing off and the coil sprin in front and the tone ring were falling of the phaser

Hi Anthony, glad you got it figured out finally! So the second time it came back was of course because of the low oil pressure in the clogged up oil screen and that also ruined the new phaser? Again.

Hey Alan, if you have time and come across that vendor I would like to know! Thank you.

Ok guys first thank you all for hints, help, suggestions, and criticism. Pulled the oil pan and inside the bowl of the oil pick up tube was a what looked like a chunk of film almost like plastic but disintegrated with carb cleaner. Removed and replaced oil pick up tube and hv oil pump again then both phasers and tensioners one more time and now the truck runs great. Has transmission issue but…
