I use a small torch if the screw isn't coming out.
There are no seals or anything that can be hurt from the heat.
The screw can be drilled out and an "easy out" used to remove.
There is a "boss" made into the area around the hole and if needed you can tap the hole to a bigger size.
I've never been able to make the screw seal no matter what I used.
Pipe tape, pipe goop, nothing seems to work.
It always seems to weep a small amount.
I just change/ check the oil a lot as the drives are getting scarce.
I do have a spare but would hate to use it.
Remember it's soft aluminum.
Driving a Torx bit in? Be careful.
