I have a 95 F-150 with the I-6 and 5-speed manual transmission. It has almost 100K miles and I plan to keep it as long as it will run. I have been careful to keep it well-maintained and it has never let me down. Does anyone have any idea how much more life I can expect out of the engine before a rebuild is necessary? I am just looking for an average - I know there is no way to predict an exact mileage.

My dad has a white 78 F-100 longbed (Uncle Jesse Duke) with the same engine and a 3-on-the-tree transmission. He brags that "it ain't never had a wrench on it" (meaning a rebuild).

 

No less than 200K. These motors have a good repuation of getting your money's worth & then some.

 

I had 211,000 miles on mine when I did a rebuild. but they were 211,000 HARD miles.

if you take care of it it will last

 

Check out the "whos high mileage king" thread in this forum, you will be pretty impressed. There is a guy who said his truck had 500,000 mi on it, and another above 450k. I'd say the average is between 200-300k.


Primary rig is Green Thunder:
95' F-150 XLT 4x4, 302, 5 spd, MSD 6A, Sunroof, CD player with 2 10" subs and some 32" BFG Muds .

Check out my Gallery for a look-see.


Then theres:
99' Mustang GT 4.6L
88' F-250 Superduty 4x4 351/c6
95' Mercury Cougar 4.6L V-8
80' E-350 300/6 with a
3 spd column shifter. Top speed is 65mph, Go Baby Go!

 

I suspect if I run across a large amount of money I'll finally rebuild mine, but me and large amounts of money don't ever seem to cross paths.

It's getting close to time to rebuild mine as the compression is finally below 120 pounds on half of the cylinders. I figure that mine will last another 20k if I baby it. Since my commute has dropped to 15 miles I suspect it'll take me almost two years to get there.

Read the sig line below and figure I've owned it for 10 years of it's twenty year existence and I bought it with 93000 on the odometer. I drove it all over western Washington and can remember putting 20000 miles on it two years in a row back in 1998 and 1999.

The body looks like heck and it leaks oil at the front seal, but the engine has never been rebuilt. No internal work has been done to the engine or heads. It has gone through 2 carb rebuilds and a couple of gaskets and that's since I've owned it. The carb was due to bad gas and freezing weather in the Olympic Mountains. But the engine fired right up with the bad float and ran rich for 75 miles at only 35mph in that condition.

I suspect that if you take care of it the engine will out last the truck body. Mine is working on it.

truthfully, I think that if I ever rebuild my 1993's 300, I'm going to convert it to as simple of a carburator set-up as I can find. The money they want for the electrical control and sensor parts I'm buying now, plus the added hassles of diagnosing problems (see one of my headaches at https://www.ford-trucks.com/dcforum/DCForumID39/4589.html ) just isn't worth it in five or ten more years.

And I'm not talking a high performance 4 bbl. carb, either.
I don't care if I lose 5 or 10 HP in the swap, or my fuel mileage goes from the mid-to-high-teens to the mid-teens. Ford's EFI is a PITA.

 

my 95 is going on 188,000 miles and i beat the hell outta it..it still runs great and gets descent milage too. i sugges keeping it stock though. it will kee it running good and also change the oil and keep the motor in good runnig condition

 

250 000+ k's easily on them

 

I noww have 325,000 plus on mine and have good compression and doesn't burn oil. I figure that I will be giving this to my five year old as his first car and it should still have the origanal engine in it. REMEMBER, don't over rev it and your kids will be driving it. We have a 67 F-350 ex hertz rental truck on the farm and it has alot of miles on it and we have no I dea how many miles on it and it still runs fine.

When I bought my truck, I told the wife, I'd just keep it until it wears out. Now, 14 years later, with 198K on it, its still going and looks like plenty of life is left. Now she wants me to get rid of it and my daughter hates riding in it, but I love it. Its lost a significant amount of power and could use a rebuild but that would be descretionary and not out od necessity.
