Dipstick tube removal

[Andersonville]

How do you remove a dipstick tube from the mighty Cummins? I think mine is cracked and blowing oil out under pressure. Thanks

It is pressed in and has an oring on it to help it seal. They are a pain to remove without damaging the tube. I had my pan off so I just tapped it out from the inside. Shadrach
