I saw a post in "Engines" asking who was in the 100,000 mile club? I though there might be some interest here. If you have a high milage 4.2 V6 let us know, and feel free to pass down some wisdom. I have a Bronco II 4x4 with 177k original miles. It is a great truck and other than the power steering pump, shocks, and nice BFG 235 70 15 tires is completely original. My new 2003 F150 4x2 4.2L is running great at 1000 miles .

My tip to you all is drain your engine coolant regurlarly, and put some Ford, or your favorite brand, of stop leak pellets in with the new fluid. Im going to do this at 50K on my 2003, and try to ward off the gasket issue, just in case. LOL

 

98 XL, 118k miles. Had gaskets replaced 3k miles ago. everything else is perfect

 

Approaching 96k miles.Had my lower intake gaskets replaced at 80k miles. :santa:

 

97 XL 2wd 4.2 with 212,600 miles all original including water pump and alt. It has Lt 265 75 16" tires ever since the originals wore out. Oil change @3000 Quacker State 10w30 & Fram filter. I did have problems with the Auto trans had it rebuilt & a large cooler installed . Still Runs like new and looks it to.

 

2000 XL 4.2 manual 102,000 miles... the only thing original on my truck will be the engine... alt and whole drivetrain gets changed once or twice a year... but thats b/c how hard i drive the truck... oil is changed every 3,000 miles along with filter... 10w30 castrol GTX and STP filter... plugs, wires, and coolant never has been changed... but im giving her a good tune up next weekend....

 

I just hit 116,000 today. No problems . . .

 

142,000 miles on my '97, original engine. Spark plugs, wires and front brakes at 93,000. Replace rearend at 124,000. Replaced battery at 6 1/2 years. Drained and refilled trans at about 90,000. Used Motorcraft 5w30 until about 115,000, now use Castrol 5w30 and Fram or Motorcraft filter. Gasket replaced under warranty early on for water leak. Added stop leak to radiator about 2 years ago for water disappearing from reservoir, was seeing some steam and smelled antifreeze on startup. The stopleak fixed it. It leaks about one quart of oil in 4,000 miles. Overall, I couldn't ask for a better vehicle at this mileage and nearly 7 years old, rides and drives like a new one.

 

Nice to see some good numbers for the 4.2. I really like the truck, and the fact that I can see the plugs and wires. I told my salesman I was getting the V6 because it looked like a servicable engine, over the v8's.

Bartruth, that is exactly how I plan on maintaining my F150. I run a little stop leak in all my vehicles, as insurance, especially the one with Dexcool, it is bad stuff.

If you repost, why did you switch from Motorcraft 5w30 to Cast. I too use Cast 10w30 in everything else, and Im just curious.

Keep the posts coming, and keep on wheeling.

 

Hell yeah im over 100,000 miles, i have one 4.2l that has over 225000, all original, rolling on 265/75r16, an another 4.2l that has 120000, all original, rolling on 265/70r17, but i have had one where the motor went out i like 110k. but hey 2 out of 3 over 120k

 

oh and by the way both the 225k and the 120k are both manual transmission, the auto is the one that died on me

 

I have a 97 f-150 xl 4.2L with 206,000 miles on the original motor. My check engine light has been on for the last 60,000 miles or so. According to the code that is making the light turn on i am losing compression in the #1 cylinder. The idle is rough when i start the truck but other than that it runs great. I have also been running 35" tires with 4.56 gears for the last 100,000 miles or so. I'm very glad to see after reading this post that there are people out there with more miles on their trucks than me! It gives me hope that there might be a little more life left on my motor.

Howdy,

I had 136,000 miles on mine when I broke the engine. Replaced it and now I'm back on the road.

I have a '91 Escort 4/5-speed w/ 238,000 miles that still runs great. It will hit the rev limiter (6,200rpm's) in 4th gear even.

Guys I have a fully stock 97 ford f150 w/auto tanny(tranny is as smooth as can be). It has 170,000 miles! Never rebuilt or anything still runs good.

thanks,
Brad



also have a 2002 Ford f150 Thunder. Thunder is a upgraded lightning package. 18" rims, catback dual side exhaust system, euro's, fog lights, type of side skirts, fiberglass bed cober, and some type of winged rear bumper. I also have a few mods to the engine: Airaide intake, Helix throttle body spacer, and a chip, but not sure what type(It came w/the truck when I bought it w/12,000miles).


ALSO LOOKING FOR ANYONE WHO HAS TURBOED A 4.2. IF NO ONE KNOWS I'M GOING TO CUSTOM MAKE IT W/ONE OF ONE OF MY FRIENDS. WOULD LOVE TO KNOW WHAT YOU GUYS THINK!

Thanks,
Brad

 

turned 112k on mine still tryin to blow it up so i have a reason to rebuild it with some head work and other custom stuff.

only problems i ever had was O2 sensors at 50 k and dpfe sensor at 107k

still need to get around to lower intake gaskets and clean out egr ports.

 

299,980 miles***V-6 4.2 1998*** On my way back from the moon! The oil pressure guage is not reading like it used to, every now and then lately. Have a noise up front. Watch out for those money guzzling shops who want to do nothing but drop a new engine in. I have a few suggestions if any body wants to beat the (whoopee?) 100,000 mile club.
