You can't simply weld an oil passage for the oil switch. If you had overwelded the passage, it could get clogged. You should have drilled out the old switch instead.

Get a new switch. Measure the size of the threaded part and get a drill bit that is smaller by at least 2 mm. Drill through and use the stud remover to get the part that is stuck to come out. You might need a punch that is sharp if the thread remover does not work.

I was tempted to stop answering your question by my professsionalism tells me not to.

Anyway, good luck.
