303518.6 miles on a 5.4 in my 06 work van and it still runs like hell! i have 120k in on 076scab with the lariat and 5.4 3 valve with the edge tuner and i love it. best engine experence ever

 

Just turn 30k on my 06 fx4

 

^30k? That's quite impressive

 

just hit 218,000 on my 05 screw lariat. Owned since new. Still on original cam phasers. Oil changes every 5000, motorcraft 5w-20. 6" procomp lift, Superchips tuner and magnaflow exhaust, K&N intake since 10,000. Also pull a 7000lb travel trailer since 180,000. Did have a shift solenoid go at 172,000 and tore some things in the tranny. Now has a remanufactured tranny through the dealer. Best truck I've ever owned.

 

26,700 on my 2005

 

98,000 2006 fx4

 

Good for youz guys with lots of miles on a 5.4L 3V, that is how an engine is supposed to perform - lots of miles year after year. I got one of the 04 POS engines that had major work required at 34,000 miles under original warranty. It died at 98,000 due to oil starvation, burnt valve, and warped head. Now I have a new POS Ford reman 5.4L 3V to live with. That cost $$$. Wrote a nasty letter to Ford, got a typical mealy mouth reply from Ford. This is my last Ford, lost all faith and confidence in this engine. I have paid enough $$$ to hold this opinion.

 

123,000 on my 04 5.4 3v

 

185k miles on my '04 Super Crew. I can't recall anything major other than routine maintenance so far (knock on wood). Handed it down to my kid about two years ago.

 

147K no issues

 

192k and counting on my 05 FX4. Original everything exceot COP's and plugs. Going to some much needed maintenance when i get to 200k

 

Just turned over 150k on my 06

 

Now at 153K. Did new plugs at 110k and also flushed the tranny. Have cleaned the MAF about 3 times after 100k when it wouldn't idle properly. That fixed the issue.

Had a rear pinion gear go out at 100k, but that is all that has gone wrong. Great truck.

2006 FX4

 

Mine 2006 has 151K
I have to change the gear of the rear differential because is making some noise after 45 mph but other than that runs great.

 

101K on my 2006!
