well yea, that make sence, u right about spinning. So im looking at the first pic, which is here

i can see that speed sensor is the one which above Shaft, clip on top and yellow end on bottom, right? and then the thing ive circled in red, is that OIL sensor that you referring to? that is broken? please look at this pic again.

That'* the part that threads in to the filter adapter, the part below that is what broke off of that.

so what i circled in red, that thing that is in the adapter, thats the sensor sending unit, right? i got confused about you talking this: "the part below that is what broke off of that" i mean what part? Do you actually see a broken peace of it below it?

shoot! thats embracing!!! i got it now, it is indeed one broken peace. To my own emplacement, i was in hurry and newer even touched anything, just raised a car and snapped pics. I just got out from under it, since i been talking to you back and forth, and yea, that yellow plug thingy, was actually broken off sensor laying behind a boot. Thanks Dan! so now all i can is to hope that after i replace it, the gauge will pop right back up, (that the engine does have good PSI in it).

I may have a few in my drawer if you want one a bit cheaper then new.
