Nice to know now, where were you when my kid bought this thing? I all honesty, I’m head over heels for the old girl and I actually like the Triton. Plenty of power, rides like a dream...likes some gas though. I’ve been tinkering and giving her plenty of TLC. She’s responding. I get smarter by the day on count of her.
Not challenging your statement but just what makes them the problem children versus the earlier and later years? Please share and let’s see what all we can learn. Thank you.

Not an expert by any means I've just read a lot on the early 3v like timing and cam phaser issues and the 2 piece spark plugs which commonly break doesn't happen with all of them but extremely common and very expensive .like I said I am not an expert just looking for other people's opinions.

The 05, and 06, and early 07's had the worst problem with the oil pumps. Also to make matters worse they had gaskets behind the phasers that leak. When that happens the oil pressure to the phasers goes wonky, and either retards or advances timing when it shouldn't. Moving along, Ford decided putting an outside fuel pump driver module up near the spare tire would be a good idea! Wrong, they get moisture, and crud in there, then the fuel pump stops pumping. And lastly you've got those original 2 piece spark plugs, which hopefully have been changed to the one piece ones. The good news is, if the previous owner was real diligent about oil changes, you may not have a problem at all. A good friends son has a 06 F150 pickup, same vehicle, and hasn't had a lick of trouble. He's real on it when it comes to maintanence, and so far he hasn't had to dig into the motor at all.

love my 05... 130k i did the phazers and complete timing kit and lifters. except the oil pump.. didnt know at the time they were problematic... but I has 170k miles now and still runing great... I do use 5w30 oil now full synthetic. I did the fuel pump module too and under coated it to protect it from corrosion. I change the spark plugs every 40k miles and use ant-seize. they come out every time.

I love my 2005, changes out the plugs about the same time as you, never knew about the oil issues though?

If you have an ounce of brains, you will buy either an 03 or 04 with the 5.4 engine (it's a 2-valve, of course) and never buy anything newer. The 5.4 in my 03 XLT 2WD has around 250K and has been bulletproof.
Lol. Yes, I do have a few ounces of brain. I own a 2006 Lincoln Navigator with 120k miles. I went with the 06 because of the upgrade to a 6 speed automatic. Older than 05 came with the 4 speed. Much smoother shifting and overall better feel. I do synthetic oil every 5k miles with no problems. Neighbor put 200k on his 05 expedition with no problem other than coils which they all have that problem. Just speaking from my own personal experience, not just internet talk
I have an '06 with 165k miles. No major issues, been holding out on changing the timing belt/chain and water pump. Have the bubbling paint, not sure if that an 05-06 only issue or just Ford, but at least it isn't mechanical.
The paint "bubbles" on the aluminum tailgate mostly and could also appear on the hood edges. It affects many years and appears that the aluminum was not etched properly before applying the finish at the factory.
i am having an issue with my 05 expedition 5.4 3v. my coder is saying Intake (A) Camshaft Position Timing Over Retarded (Bank 2) i have replaced the VCT Solenoid on the drivers side but the code is still there. SUV runs real good except sometimes when i stop at a red light or idling it starts to shake but goes away soon after. also, when i bought the SUV it didnt have the catalytic converter so it also has that code. any ideas?
Its Ford I have it on my 03 (bad) and my wife has it on her 07.

I have an 05 with 290k all original runs great have had no issue just normal maintenance. The 3v big issue is with the cam phasers they will need to be replaced eventually. So that cost would need to be calculated in along with the updated melling oil pump and VCT Solenoids. The average cost from an auto repair shop is $2200 to $2400. I still have not replaced mine but planning for a complete redo in the next few months. My experience may be different from others but I have had the cam phaser noise just past a 100k. I maintain my vehicle very well and do not beat up the vehicle driving I have replaced the VCT Solenoids and the sound has stayed the same since they started ticking. Note: I purchase used in 09 with 34k on the engine. So if you are concerned about the 3v issues then you should look at a different year.

Instead of spending 2500 on cam phasers for an 05 to 07 it would make a lot more sense to put it towards an 08 or newer and eliminate the problem altogerther.plus spark plugs can cost a small fortune in those years.what a great idea to make a 3 piece spark plug that welded itself to the head.
