2000 Dodge Caravan oil dipstick

Can you upload a pic of what is left so I can see what you are dealing with?

I don't no how to upload a picture the oil stick is inside the tubing and I don't have anything to grab hold to to pull the oil stick out.

If there is nothing to grab, the only thing I can suggest, short of removing the tube, is a magnet or a very small set of needle nose pliers. See if you can grab it and let me know what happens. If needed, I'll explain how to remove the tube, but that is a last resort.

how do I remove the tube? I couldn't grab it with a magnet or needle nose pliers.

how do I replace the tube for the oil dipstick?

If you follow the dipstick toward the engine, you will see a bolt holding it in place. Once the bolt is removed, the dipstick tube will pull out of the engine. There will be a rubber o-ring at the end. Make sure it is in place and not damaged when you reinstall it. It is a good idea to place a thin layer of oil on the o-ring prior to installation.
