What is the most miles anyone has logged so far with either the 5.4 or 4.6 Triton engine? I just bought a '99 F-150 with the 5.4 and would like to know what kind of total miles I can expect out of the engine assuming oil changes every 3,000 miles and running Mobil 1.

------------------

 

I have a 97 F-150 with a 4.6 (Romeo) and it has 176,000 miles on it. It uses 1-2 quarts of oil in 5000 miles. It runs great and still has good power. It does make a slight knock (wrist pin?) when stone cold that goes away in 10-30 seconds depending on temperature. Triton motors are said to commonly last 300,000 miles in police and taxi service. These are very good engines. The biggest complaint I have heard from fleet mechanics is that the factory plug wires don't last much over 60,000 miles, though I think mine still has the factory wires.

 

WOW! where do you go to put so many miles on yopur truck?
Have you had any other problems with your truck?

Last year my company did a transmission test on 2 F150 with 5.4 and new transmission, was given a spare transmisson, test was to last for only 25m miles, at 250,000 miles test was stopped, 5.4 started using a little oil, transmissions operated flaulessly, had pan off tranny once, replace pans with out replaceing with new gaskets, never leaked, oil used was ford's, test was done for Ford. No need to tell you I'm a owner of a new F150 5.4. Since last I have been driving Dodge trucks , I'm happy to get into F150 in morning to go home.

 

It's about time we got some upbeat news on this board !

 

Bent6,

How has the rest of the truck held up so far?
Do you have a lot of squeaks or rattles?
Is the steering still tight? Are the seats still comfortable? How has everything held up in general? How much longer do you plan on keeping it?

My 4.6 Romeo runs great at 3,000 miles. I am knida glad to hear it has such a promising future.

Seacrow,
The rest of the truck is great. There is lots of sandblast on the windshield and grill shell. There are no sqeeks or rattles except for the things rolling around in the door pockets. The steering is still as tight as a new truck. The binder clips on the rear leafs got lose and started to rattle. I cut them off and replaced them with the 4x4 recall parts. There are no oil leaks. The seats and interior are near perfect. The drivers side door panel has an elbow mark/dent on the top of it. It has all of the typical F-150 problems: sqeeky steering, leaking rear window, start up engine noise, pitted right rear wheel, warped rotors(by me), and worst in my mind rust starting on the bottoms of the door and tailgate.

I have only had the truck for about a year. I bought it with 165K. It is a loaded S/C LWB XLT. I paid $8200 for it. I was owned by the local electrical union and spent its early life going from Chicago to Georga. I did speak with the driver. He said no problems ever and that the oil use started at 100K.

I plan on keeping the truck for another 10 years or so. As tight as the truck is and the way the miles were put on, I feel it will go at least another 100K with no problems. Even if I do wind up putting an engine or trans in it($1000-$1500 either way), I feel like I'm money ahead.

Just what does Ford do engineering wise that makes Triton engines last so long? Most American V-8's are shot after about 120,000 miles and I was wondering what is special about the Triton's that apparently makes them last longer? Do they use special bearings, piston rings, valve guides, etc? You hear stories all the time from guys with Toyotas with 22RE engines that have 200,000 or 300,000 miles on them, but you hardly ever of an American V-8 that lasts that long. I traded in a 93 Toyota with 100,000 trouble free miles on my new F-150 and I hope I can look forward to at least that many miles on my new Ford.

That overhead cam makes a big difernce from the old push rod type.

 

Met a fella, last week with a pretty beat up 97 sc 4x4 with the 4.6 with 325 000 kms!
I heard the truck idling and it sounded mint.
He said that he had some problems with the 4x4 system soon after he bought it but nothing since. This should bode well for the rest of us.

 

I hate to disagree with you Redrider, but most American V8s are capable of 200,000 miles if you keep the oil changed. My '93 5.0 (an engine design dating back to 1962) has over 160,000 miles and runs great. When I was a kid my family put over 150,000 miles on a '68 Plymouth and it ran great when we sold it. We replaced it with a Chevy van and put 140,000 miles on it. It ran great too, but the body was a rattletrap. The American 4 bangers and some V6s are the ones of questionable quality. Although my previous Company had some 4 cylinder Taurus' that took incredible abuse for 100K and still ran good.

Equipment of all kinds, including engines, wear out quicker the more start and stop cycles it's exposed to. Case in point. We all knock Chevies and Chevy engines, however, take a look at the NYC cabs. Haven't been there in a few years, but at one time, the yellow cabs were all Chevy Caprices and they've rolled over the odometer 2 and 3 times. Nothing unusual about it. Oil is changed regularly and the engines are running most of the day.

Ask any engineer. Short cycling is the kiss of death for the vast majority of equipment both mechanical and electronic.

 

Dennis ... Remember Chequer (sp?) cabs? Someone told me that it wasn't unusual for those babys to last well over a million miles. Several years ago I went to Key West for some fishing and noticed the police cars there were Chequers. They told me the same thing ... well actually they said ("Get up off the sidewalk you stinking DRUNK!") It sounded like "My car has well over 1.2 million miles and is still going strong".

 

Tenderpaw theres no way a chevy engine can go 140,000 miles a chevy engine is lucky to go 10,000 miles before a rebuild I know this because a friend of mine from work had a chevy that blew the engine after 10,000 miles.

 

hmustang,

Never say never...I have a 1990 Chevrolet Astro 4.3 liter V-6 work van that has 183,427 miles on it. Runs excellent!! Only problem I've had in the two years I've had it was the thermostat go bad ($5 fix).
