This is going to sound kinda Bubba, but find a torx that is a little too large to fit in the allen socket in the plug. Use a hammer and pound the torx into the plug as far as it will go, hoefully to the bottom of the socket head. Try and remove it with a ratchet now. The torx bite better than an allen. I have had this work for more than once, although not always. It's better to try this first instead of drilling through a plug that leads to a main oil passage that will allow filings to fall into critical areas of the engine. You will not get it all out either unless you do a complete engine disassemble.

If you can't get the plug out, go to the lower, rear, left driver side of the block. Your oil sending unit should be there. "T" into this passage.

Thanks for the advice. I'll might try the torx tip.
But about the lower rear left side position I already have a "T" with one gauge pressure unit and a oil temp unit. Either I need to remove my oil temp gauge/sender or find a combined unit with both gauge sender and switch...

The torx bit and a hammer worked like a charm. I now have the pressure switch mounted.
Thanks for the advice!
