I have always found it amazing how many miles a truck can last when proper maintenence and common sence are used. I've seen people that have their trucks destroyed by the time they hit 100,000 and others who's trucks are just getting comfortable hitting twice that.
My '86 F150 has what is assumed to be 142K miles, but you can't say for sure since the mileage reading only has a 5 digit figure, but since it is kinda on the rough side, i'd say it has at least turned over once. Maybe twice, but that's highly unlikely, even though it probably will since I plan to keep it for quite some time. And no, my avatar pic is not of my truck, I lost my cam b4 I bought the truck and haven't found it since, but plan on buying another camera when time permits. Seems to be running strong still, no burning oil or major leaking from what I can see.
My '86 F150 m/t has right at 340K. Original motor no major work done to motor or tranny....yet. I hope it stays that way for many more years to come. My friend bought the truck new in sept of 86 and I have been bugging him to sell me the truck for quite some time.
It has the 300 I-6 with the manual tranny but I am not sure which one it is yet. I just dropped it this past weekend to replace the clutch and I have yet to finish cleaning it. I got a pilot bearing removal tool from the parts place and it didn't work so my buddy made me a special slide hammer at work so I get to try it out tomorrow. We also went ahead and replaced the u-joints and trans mount since it was down.
mine has 250,xxx but the engine only has about 1000 mimles on it since i rebuilt the motor in the spring. its runs so much better after the rebuild since the only original parts i used were the block, crank, and connecting rods. everything else was new including a brand new head from ford for only like $350 that inlcuded the valves, keepers, and springs too all assembled. i love my motor
