2011 F150 5.0 oil pan leak and transmission coolant line swap

Last year I did some work to my F-150. It was really fun and a little bit nerve-wracking given I had never done any work like this on my own before. It turned out well, I made mistakes and learned from them, and fixed up a very old truck to keep it going and help facilitate a move.

  • Front suspension shock / strut, sway, upper control arms
  • Transmission coolant lines and radiator
  • Transmission fluid and pan gasket
  • Oil pan gasket
  • Rocker panel covers black plastic molded
  • Interior work (water damaged)
The transmission coolant lines are prone to breaking at the forward plastic connectors, causing catastrophic failure for the 6r80 transmission.
Oil pan and rear main seal area after replacing the gasket with fresh RTV. The oil leak stopped.

The oil pan gasket was leaking which prompted me to investigate and found that there was oil dripping off the bottom of the rear main seal. The rear main seal is not leaking and I have changed out the gasket for the oil pan. The oil pan is tough to finagle out of the truck and it requires the front differential to be lowered. The oil pan gasket has held luckily for more than 6-months now despite a bolt shearing on the rear passenger side of the oil pan. A single bolt is not enough of a problem when you have fresh RTV.

The sway bar end links provided noticeable improvement for the ride quality.

Upper control arms and shocks. Not OEM so we’ll see how long they last…

I swapped the carpet out of the interior for some ebay vinyl. Removing the supercab seats is annoying but once you do it once, you’ll be able to do it the second time in no time. Ebay vinyl floor material came as one uncut sheet. I formed and cut it to the interior and mounted the seats back in. Steam cleaning the seats, replaced the door handles, and painted the speaker grilles black. Invisible glass to the windshield and a decent android auto head unit make it feel like a new truck again.

Stitched on a leather steering wheel cover. Oh yeahhh…

Runs great through the NC Mountains. Even with 130k+ miles, the 5.0 sings.
