I've got a question:
If you look at the pic below, there is a hole immediately to the right of the oil filter, which I now know is the pressurized oil feed port (for your oil pressure sender). I didn't realize that, and I screwed the pressure sender into the hole directly above it. Needless to say upon initial startup, I made a huge mess in the driveway, followed by lots of cursing. ALWAYS have a friend there to watch when you first start your engine in case of any leaks! Anyway, we caught it in time, and I plugged the pressure sending hole temporarily with an aftermarket sending unit. Now my question is, what is supposed to go in the hole directly above the filter just to the left of the freeze plug? The reason I stuck the sender in there is because I saw it goes into a passageway in the block, and I made the wrong assumption. I can't see it in my dis-assembly photos, because the wiring harness blocks it.
