Shop with Blessed Performance for the 73DipStick Adapter Repair Kit for your Ford 7.3L Powerstroke diesel. The leak at the dipstick flange is a well known issue with the 7.3 Powerstroke motor. The leak develops because the factory O-ring mounted inside the adapter swells over time due to exposure to oil. As the seal swells it actually deforms the inner piece of the adapter causing the outer nut to loosen. Some people will try tightening the nut to stop the leak and that can work temporarily, but it only deforms the inner piece more. This kit reuses the internal part and moves the seal to the outside of the pan. Nothing left abandoned inside the pan and no welding. This is currently the only product on the market that creates a permanent repair for the oil leak at the dipstick adapter in the oil pan that reuses the factory adapter. This allows the leak to be reapaired with the pan on the engine and no parts abandoned inside of the pan. This kit can be installed with just basic hand tools, no need for special tools.
DISCLAIMER:
It has been determined that this kit ONLY WORKS with Factory or Dorman internal dipstick flanges. If the internal part has ever been replaced with a part not made by these two manufacturers, this kit may NOT work. Also, if the dipstick nut has ever been overtightened, and the threads are pulled, you could still end up with a small leak.
