If that is a four cylinder. Look on you tube. All on top. Should not be too hard.

Could try one of the following:

*Find a socket, pipe, etc. that fits snugly into the tube. Wrap tube as low as possible with tape or other material wrap to prevent damage when gripped with vice grips. Rotate grips and pry out tube.

The socket, pipe, etc. will help prevent the tube from being crushed by grips.

Keep in mind if unsuccessful in removing the tube. Any installed socket, pipe, etc will need to be removed from the tube from the top.

*Make an adapter plate that bolts to the tube using the large tube nut while allowing a slide hammer to also attach to the plate. Then engage hammer to pull out.

*Install sockets, etc. into the tube to allow a base for a jaw pullers threaded bolt to rest on. Engage puller jaws on tube nut to pull out tube. Caution not to damage spark plug threads by whatever is installed into the tube.

Double up the installed nuts to allow more contact with the threaded area of tube when applying force.

If the tube does come out, it will need to be reinstalled. Could freeze tube and slightly heat hole with propane torch.

Clean removed tube and hole. Use a bearing locker fluid. Loctite, etc. that can withstand oil.

Could try to cool tube prior to removal via dry ice inside tube and slight heating around tube base with propane torch.

Localized heating of the aluminum area might help to remove tube but if too hot may warp the head.

Make no claims any of the above will work or will not damage tube.

Personally would find a high temp oil proof epoxy (not silicone or a gasket material). A viscous epoxy to allow better flow better into the space between the tube and hole. Then allow to fully cure before starting engine.

The metal areas would need to be very clean and perhaps abraded with something like Scotch-Brite.
