Description
7.3 Dipstick Part # 110448
The leak at the dipstick flange is one of the most common oil leaks on the 7.3 Powerstroke. The factory O ring inside the adapter swells from oil exposure, deforms the inner piece, and loosens the outer nut. Tightening the nut only makes it worse, and the factory fix means dropping the oil pan.
The 7.3 Dipstick kit fixes it from outside the pan. It reuses your factory internal adapter and moves the seal to the outside, so nothing gets left loose in the pan and no welding is required. Install takes about two hours with basic hand tools.
Features
- Permanent external repair for the 7.3 Powerstroke dipstick adapter leak

Fitment
1994.5 to 2003 Ford 7.3L Powerstroke
Important: This kit works with factory Ford or Dorman internal dipstick flanges only. If the internal part was ever replaced with another brand, the kit may not fit. If the dipstick nut was overtightened and the threads are pulled, a small leak may remain.
Installation Video
Installation Instructions
- Disconnect the negative cable on both batteries, since the starter has to come out.
- Remove the engine oil dipstick and the dipstick tube hold down. On early models it sits near the middle of the valve cover; on later models it is at the front of the valve cover.
- Remove the starter.
- Pull the dipstick tube up out of the adapter.
- Insert a holding tool into the adapter so it can't fall into the oil pan. Tie a wire or rope to the tool so you can retrieve it if it drops. Note which direction the dipstick tube hole faces. It must face the same way when the repair is done or the tube will not go back in.
- Remove the factory nut from the outside of the adapter, slide it over the holding tool and discard it.
- Carefully push the adapter into the pan and pull the O ring out from inside with your finger or a pick.
- Pull the adapter back into the hole and clean the surfaces well with brake clean and rags. Wire brush heavy buildup if needed. Confirm the tube hole is still facing the right direction.
- Spread a thin layer of Ultra Black sealer on one side of the gasket and slide it over the tool, sealer side toward the pan. Line up the two notches in the gasket with the notches in the adapter.
- Apply a little more sealer to the adapter threads, slide the stainless washer over the tool, line up its notches and set it against the gasket.
- Slide the new aluminum nut over the tool and carefully start it on the threads. Tighten with slip joint pliers or a wrench until sealer squeezes out around the gasket. Do not overtighten and strip the threads.
- Once the nut is tight, remove the holding tool.
- Remove the old O ring from the dipstick tube and install the new one in the groove. Coat it lightly with sealer or silicone lubricant and push the tube back into the adapter.
- Reinstall the dipstick tube hold down bolt.
- Reinstall the starter.
- Reconnect both batteries.
- Start the truck and check for leaks.
