I'm currently at 321k

 

I have read so many forums about how bad the Ford F150 5.4 Triton engine and transmission is, well today I reached 250,000 miles on mine, and have to say either I am lucky or I do take care of my truck, but I have changed coils, mainfold, alot of brake pads and tires, and lots of Mobil one oil. I have changed the trans fluid probably every 50,000 miles, I'm not the best on fuel filters, but I use this product Dyno-tab, which is fabulous. I have heard about the spark plug issue, but I changed them, and used anti-seeze paste, like they recomend. It has had that anoying tap, and sounds like a knock when cold since it was new. I guess it must be nothing since it is still running sweet. Im starting to get this stumble when under light load, I read its the Oxygen sensor starting to go, might attempt it over the winter. THe exhaust, is original too. I'm hoping that this does no jinks me, because I want to take it the next 50,000 miles before giving her up. So I hope whoever gets tired of reading the bad threads, that they read this, and see there are some wonderfull Fords out there. The only bad thing I see down the road in the future, is that a replacement is $50,000

 

I'm running a 2000 E250 with the 5.4 gas motor----has reached 273K miles without any problems--still runs pretty strong too.

Best thing was I bought it with 203K miles---it was and still is maintained properly.

(Old thread I know but good to update these from time to time!)

 

Currently have 237k oil change every 4-5k regular oil. Only had to replace throttle block motor so far.

 

we have 2 at the body shop that are used as parts runners. one has a little over 560,000 on it, the other one has a little over 610,000 miles on it.
both still purr and have never been opened up.

 

Just noticed my step dads 03 f150 has 175k on it. Damn thing runs perfect still. He bought it in 09 with 95k on it.

 

03 nav with 170k but it just puked a plug out of number two cylinder ruined cop and threads I believe

 

I have a 2003 F250 bought brand new January of 04. I have just over 225,00 on it. Basic maintenance for most part. I did have #6 spark plug blow out. After it happened the second time no problems until now. I just replaced the battery this week and now it won't start at times, not even a click. I take the key out and put it back in and turn ignition switch and it will go. Sometimes it takes 2 or 3 tries though. I hope I am not getting to the nickel and dime part of owning the truck now. Any thoughts on my current issue?

 

I have a 01 expedition with the 5.4. Last summer it started missing and lost compression on #3 at around 175,000 miles. I went ahead and changed the engine out with a fresh rebuild. I got it at 77,000 miles. The 100,000 I put on it were hard miles, pulling a 32 foot 9500 pound camper all over the country. I am not great about remembering oil changes. I never did pull the heads to see why I lost compression, I am suspecting a broken valve spring, but it was starting to burn oil pretty bad. Until that time though I had no problems. The EGR pressure sensor had an issue, the vacuum hoses would melt and the nipple the hose slips over melted off. I had to put a new alternator on it once. I also had to replace the front brakes once. Now it eats batteries. For some reason once a year the battery goes bad. So far in the last 4 years I have gone through 5 batteries all with a bad cell.
My pickup is a 99 F150 with the 5.4. The kid I got it from was not good to it! It is pretty beat up. The original engine spun a bearing and locked up at around 115,000 miles. I got it with around 35,000? miles on the rebuild. It is not in my shop torn down again with a spun bearing due to timing chain issues.
My dad has an 05 F150 with the 5.4. I think he is over 200,000 miles with no problems yet. It does have a bad knock when it first starts up, but still runs great once warmed up.

 

I'm running a 1998 E250 with the 5.4 183K miles without any problems still runs pretty strong too. I am original owner. Spark plugs and coils only.

 

Although not nearly as impressive as some of the other posters, my 2000 Expy E.B. 5.4 has over 108K on it and it tugs a 5,000 LB 23' Travel trailer where ever I ask it to without complaint.

Still pleanty stout even nearing 14 yrs old!

Please delete.

 

Sounds like fuel pump is going bad. Are you replacing the fuel filter every 15k miles?
