of a note when I bought my 2003 f150 back in 2010 the ford garage knew these had a knack for the seal to give out on high milage rigs between the transmission and transfer case . He checked mine and sure as chit the tranny was losing oil into the transfer case . If your transfer case is dripping out oil from the breather this is why .

 

I have 270000 miles on my 2000 f250 sd and just had to replace the exhaust manifold gaskets. other than that it runs great and pulls great.

 

I have a 2000 f250 sd with 270,000 miles on it and still runs great! thanks Ford for making such a good engine!

 

I have 185,000 on 5.4 expy. Engine is so full of life. Girlfriends old boss has expy with 325,xxx and going. So between 200 and 400,000 mi. Seriously. They are good if you take care of them. Motorcraft or napa gold filter. Must have metal anti dbv. I run 15w40.In everything. Period. Live in michigan and have instant oil psi at 2 deg f. So ya grsat motor. The 02 - ?? Vct had some ticking issues but still great. Always use metal end oil filters. And strong anti drain back valve.

 

Im thiking about buying a 2004 fx4 f150 with 216000 miles on it, truck is very clean, was registered as a fleet vehicle so im thinking the maintenance was kept up on it, going to test drive today. Ive read that if the cam phasers are bad it will make a ticking noise after it reaches operating temp. Is there anything else I should check really good to warn of major issues?

 

And I also read about the seal between the transmission and transfer case leaking, to lok and see if fluid is coming out of breather

 

our 05 was supercharged from about 20k miles and made it to 160k before it went out...threw a reman from ford in it put the supercharger back on it. tranny made it to 175k, got it rebuilt and am at 200k now. we had a 4.6 in a 97 that went to 300k before it quit, well was running on 3 cylinders but still drove itself to the crusher.

 

IS the leaking seal on those with automatic or manual transmissions?

 

The '98 was bought w/100k on the clock, no records no manual. No real issues, work out of it with gross weight of 8,000 lbs ALL the time. lots of highway miles, quaker state dino oil changes w/motorcraft filters. rear pinion bearing seal went at 300,000miles, replaced seal only, rear brake lines rusting through, retired to fishing truck and bought a 2004 w/100,000 on the clock. Still running lots of highway miles, still using quaker state. The 1988 van 302 ran 330,000, original trans & motor and drove to the junkyard, the 1994 van, 302 at 290,000 is on original motor, but trans rebuilt twice (wife drove that one!) still running as a crabbing truck (nj) I guess I'll have to stop changing oil to get rid of them!

 

I'm a boat captain and pull a 9,900 lb boat on a daily basis... 330,000 miles and still rolling strong ..and it was a northern truck prior to my ownership.. Had to replace the bed (due to there not being much of a bed left )BC of rust ,and normal stuff (ie.coil packs ,voltage regulator, idler pully ,shift cable, column components, what you would expect out of a 330,000 mile truck). As I type this I get a txt msg ftom pops that it's broke down (battery connection issue I expect) lol

I'm only a little less than half way there! Nothing done (except plug changes & stuff) that's considered way beyond normal maintenance.

 

Half a mil is a great accomplishment, but we've got a guy on the Van forum who runs a fleet of long-distance transport E vans. He has 3 or 4 E vans with over a MILLION miles on each. (They are about model year 2006--and remember the vans kept the 2 valve engine). He is getting 800,000 miles out of transmissions on 5.4's and *only* 500,000 with 4.6 engines because the trans has to work harder.

EDIT--look at this thread. Photo of some spark plugs and a serpentine belt that he ran for 429k miles (cough):

So half a mil is great, but over 1.3 million is really great. Read down the thread a bit and he talks a bit about his fleet of vans.

185,000 on my 2001 F250 5.4 4x4 with no major problems with either the engine or the transmission. The only issues I have had were minor and included a cracked manifold on the passenger side, a new alternator at around 150,000 miles, and minor oil leaks.
