so i was putting my oil pressure guage in and like anyone i was extremely excited to get it down and see how it looked and worked. after i got all the wiring done and the sensor hooked up i put the new oil in, got in and started it up. LOL then i heard a swoshing sound like oil dumping out. in all my times of changing oil this has never happened. so i thought i t was the sensor. i got out and all my new mobil1 oil was laying on the ground. I forgot to put the damn oil filter back on, aaaaaaaaahhhhhhhhhhhhh i was so pissed, so i finally got it al fixed and done it works great. anyone know what oil pressure and mp3 runs at?
