Head gaskets are bad 13500 miles only. Spark plugs are also bad replaced 1 and it cost 750.00 to replace that one come to find out the motor is junk. The ford dealership said cut your basically cut your losses they could find motte problems such as Transmission it’s not worth it and I’m not willing to put 10,000.00 more dollars in this truck and have it do this again in 39000 to 15300 miles.

182k miles on the clock, Been used as a work truck its whole life and its still going hard! Most maintenance thats been done is Oil Changes!

I purchased a used 2003 f-150 supercrew short box 4x4 that had been in a roll over and has 409,694km on it all original for $1000. the body took very little damage the family that owned it sustained zero injuries and it landed upright after rolling twice (on the coqihalla highway between Merritt and Hope British Columbia Canada in 7 feet ofs snow hence not much body damage) how ever the suspension and steering system took on some life threatening injuries but after only 6 hours in the ICU with a flux core treatment and some oxy acetylene therapy he once again runs strong. He is now on the wait list for ball joint replacement surgery as his bi-weekly medical coverage was maxed out after the life saving procedures he received. Currently he is on a prescription for 6 pumps of Lucas extra tacky with anti seize directly to all four ball joints twice a week to reduce inflammation, along with half a quart of generic ATF fluid once a week due to a weak front pump seal (genetic disease runs in the 4r100 family) currently on wait list for full transmission rebuild with all forged and cyro treated internals plus pump seals made for the 7.3 power stroke (5.4 triton shares the same transmission as the 7.3 power stroke) power stroke seals are built from a stronger material and designed to handle more torque and high temperature from constant load at low speeds. Only issue I had was that the previous owner never changed the #4 and #8 spark plugs and at 400,000km they are done I removed them and cleaned with gas and stainless steelbrush and gapped them. blew out the coil packs and reinstalled with the old spark plugs. He had full power again for a 1:45 minute burnout before those antique plugs burnt out. To some this may sound like alot of issues but it only has 5 codes and are almost all due to the modifications I made the first code is no air entering the intake this is because I removed mass air flow sensor when I installed a cold air I take with a 5 inch intake hose and (huge power increase did not expect it was going for a deeper rumble at cruising speed) I bet the 2 mods I did gained 50 horse power atleast. The second code is to much air in the combustion chamber lol. That one is from the 5 inch intake pipe and large knn filter. I also removed the muffler and rerouted the pipe to exiit between rear passenger door and rear passenger tire. Sounds amazing when the arc spark plugs and I gained power and almost doubled my fuel mileage (mileage also depending on spark plugs) amazing truck I use my for work (welding) and mud racing/ deep snow offroad adventures, family camping trips everything my woman has her car and yet takes my old ugly beast to work when I'm on night. shift it's unkillable!!!
