Car Information:
Ford F250
Year: 2001
Engine Size: 6.8 l v10
Trans: Automatic

Issue / Question:
My truck’s oil pressure drops to zero after it has been running for a while. When I turn off the truck and then start it back up again, the oil pressure is normal. The pressure only drops when the engine is hot.

Answer:
Sounds like the sump is getting plugged up with sludge. I would recommend running a mechanical oil pressure test first. If it starts to fade at 2000 rpm after running a while, the oil pan will need to be removed and the sump and pick up screen inspected.
