I'm in the process of cleaning up and painting the engine on my '53 3100. I'd like to remove the dipstick tube so I can clean it and paint it better and I don't want to destroy it in the processs.

How do I get this tube out? Does it unscrew or is it pressed in?

I can't get any wiggle out of it at all.

Now that I've got the oil pan off can I put a snug fitting punch in the bottom of the hole and tap the tube out from the bottom?
