Bought my first Powerstroke 2 days ago, and have been doing some serious digging on here and on the truck to get a grasp of what all is going on... only mod that I can visibly see is that the stock muffler was cut off and a piece of pipe added in.
- First thing I've noticed is that it runs great and smooth, but still lacks some "oomph" down low. The truck cranks and runs great at ~40 degree weather in the mornings. I had both batteries load tested, along with the alternator and all checked out great. The turbo really comes on around 2k rpms, but I feel that it is still lacking compared to friends trucks I've ridden in.
- Changed the fuel filter and air filter today. The fuel bowl was nice and clean. The stock airbox is still in tact, and there was enough loose dirt in the box that I went ahead and took my shop vac and cleaned it out, to hold me over until I can get the big filter conversion done.
- I had to add about a half quart of diff fluid to the front and rear diffs.
- The power steering pump is whining at me, which after checking it was a touch low on fluid. I filled it to the fill line and it is still whining, although not as loud. Guess I need to go ahead and replace the pump? Don't want to lose the brakes when it does decide to peace it
- Do the F250s come with greaseable ball joints and tie rod ends? I know that my F150 did not, so I'm trying to figure out if these have been replaced?
- Lastly, back to the first part about the power loss... on the ride home from purchase, it was about 120 miles of highway. With the cruise set on 73, the overhead display read 15.5, which I am figuring to actually be less. After going over the engine bay, there is not any soot on the firewall to show a boost leak there, BUT there is a significant amount of residue/buildup on the cold side pipe where it runs into the boot for the intercooler. Reading around on here, I'm guessing that replacing the boot there with new clamps may bring it back to life and pull the MPG's back up?
I'm open to any and all suggestions/tips to point me in a good direction. I'm loving it so far, and looking forward to many many miles of fun
