Some people wonder why do they make those expensive billet adaptors to use the oil pressure switch and a pressure sender... Sure the brass ones from the plumbing dept at the hardware store work... sometimes for years, but then they develop stress cracks and fall off if you really drive hard.

So I'm down for the night, luckily i was parked somewhere safe when i noticed something was odd...

if you can't do it to an aircraft, you probably shouldn't do it on your car either...
