Another milestone, I rolled it 300,000 last Friday on a 400mi round trip. I'm very pleased with the 5.4 2V longevity, it really is a fantastic engine. The 4R75 trans is still stock too and just keeps going. No new mechanical issues other than the heat shields on the exhaust rattle all the time and I can't seem to figure out which one it is lol. 300,700 miles today and the HVAC fan switch melted and stuck on med-hi, go figure :-roll

Currently sitting at 291,xxx on my 5.4L 2V, quite impressed with it as well. Aside from the heat shield rattle, I have no doubts about how reliable it is. Every time I start it up, she instantly sparks to life and idles effortlessly with a solid 14.2v from the alternator, even when towing a car. Some new non-chinese ignition coils and O2 sensors (maybe a wideband later...) would be a good idea tho.

Was an excellent $500 investment that has paid me back at every turn.

....I love to hear these stories!! I just turned 150k on my 2001, and I still love her to death!We always hop in the crewcab and away we go! she needs new lower rocker panels, but otherwise, I think I would drive it across the 50 states in a heartbeat!

My rockers are almost entirely gone which explains why the running boards & brackets are gone, and the A/C leaks a bit despite blowing nice and cool with a fresh charge, but I'd drive my Expedition ANYWHERE without hesitation. Pretty sure either LMC Truck or JC Whitney has new rockers for a good price. Trip Computer shows 450 miles to empty with a full tank, I just might have to test that sometime...

159,200 on a 2003 Merc, Mountaineer 4.6L V8 and its acting really weird. IAC was replaced to make it quit stalling out and now it high idles on start up (2000+) and when you come to a stop it sits at 1200 then drops to 800 or so. Cleaned the throttle body and the MAF when I pulled the IAC, with their respected CRC cleaners...this is will drive a man to drink, heavily.

My 06 van has 260k kilometers on the 2V 4.6L and the motor and 4R75w trans run as good as new with a fresh set of Motorcraft plugs. The motor idles smooth and makes good power for a 4.6:D, it neither burns nor leaks oil or any other fluid and the trans shifts perfectly. Working on this thing is more complicated than doing the same on an older motor but it does deliver better gas milage than the old 5.0 so maybe it's not all bad

My 2002 F150 has 209K Kms on it
My 2006 F250 has 199K Kms on it
My 2008 F250 has 299K Kms on it

my 02 has been fantastic, engine runs like a champ no major issues just maintenance stuff, plugs cops, belt, alternator etc

my 06 has been great, but just developed the cam phaser or guide or tensioner issue which will be addressed soon

my 08 has also been a great truck, it has however developed an issue that has me contemplating either fixing it as it is, rebuilding it or dropping a crate engine in it. It's been a workhorse and has never left me by the side of the road... actually all the trucks have ( except my 02 when the alternator died on me :-X04 )

So I cant say my experiences have been bad with the 5.4, so far I think I have made out pretty good with them

I did have a 04 6.0 that was passed on to me it had 498K Kms on it, but it was starting to leak oil from the bed plates , but that many kilometers on it and it never burned oil, but sold it to someone that was looking for the engine parts for a rebuild of their own 6.0 that was in an accident. So never went to the wreckers at least

I have a 2001 ford f150 xlt 4 door with a 5.4l and has 260,000 miles with original engine and daily driver..the main bearing are starting to knock but I plan on rebuilding my truck and going another 200,000 this time I'm gonna add a little more horsepower..but I love my ford:oval

I have a 2007 f150 4.6 with 197k and a 2005 f250 5.4 with 539k all factory

539K on your 05 F250 That's been one hell of a horse for ya :-X22

You sir have won a lifetime supply of the internet. Keep it up, I want to see your 5.4 hit 1,000,000 miles

Thanks guys. Still running tiptop. I hope to get her to last but once she quits its going to get a built 5.4 put in.

Hi !

I'm Mike and I'm from Warsaw, Poland. Bought 2004' 5.4 2V Eddie Bauer Expedition and thought it would be easy to take care of it...but in European reality it is not so obvious No proffesional service, spare parts and mechanics usually tells me - What's that ?
Now I'm trying to solve problem with fuel pump relay (burned second time in 3 months), missfires (sparks and colis are travelling to Poland) and few leaks (power steering). I've got also problem with criuse control as it's not responding - no on, off - steering wheel buttons are not running it...

Car is fantastic and I'd like to run it for a long time, but it's hard to take care of it cause of those small nuances.

And about the milage - 190000miles / 300000km :-)

Cheers !!

7 Fleet trucks one with 250k and the rest over 300k all stock drive train.

I have an 09 with the 4.6L. Has about 97K miles on the clock right now.
