Remove the needle is possible.
Force it in the normal direction of travel with the handwheel. You can't break it. This tip from a dry cleaners that does repairs and has 6 machines.
Then run the machine full speed with no needle for about 20 seconds.

Why lots of oil leakage?
There might be a mechanical problem with your sewing machine to oil to be leaking and it needs to be repaired and the part that stops the oil from spilling out needs to have something sealing it then too to stop oil from leaking out.
Hi! I have a Juki HZL-25Z. The under side of my fabric is getting birds nest. So I know its the top tension but I have no idea how to fix this!
To be sure it is top thread, suggest you try a thread of a different color other than the bobbin.
Assuming its top thread, you need to increase top thread tension.
Other causes; Uneven feed of top thread can cause nesting of top thread. The machine uses a horizontal spool for top thread. Be sure you use a spool cap that is as big or larger than the spool. Pay particular attention to threading instructions on which direction the thread drops from the spool. If backwards, flip spool.
