Bit of a pickle here. I discovered the previous owner of my Silverado apparently tried to force a non-AFM oil pressure sensor on, snapped it off, installed correct one over it which is shorter. I was trying to size the right screw extractor (blind) and the small one -#0 - slipped loose and I don't know if it went in, or behind the motor (no room to feel or see above the tranny).
With non - AFM motors if it goes down it can hit the cam, but schematics make it appear that the AFM oil galleys drop from the sensor a bit forward of the galley to the cam - so I'm wondering whether it can be started or not if needed.
I might get a scope to look for it, but then the problem is how to retrieve it if it is in there.
