Re: Oil pressure switch/sender (Unriced)
There are (2), I think. One in the back of the block behind the distributor and it has an oil temp. sender near it, and there is another in the left rear of the block. One tells the computer pressure and one tells the gauges. Neither measure flow and both monitor the complete oil galley pressure... Hope this helps...

Re: Oil pressure switch/sender (Unriced)
Curious, I think my oil sender may be on the fritz.
Where in the oil path does the oil sender monitor
the oil flow/pressure? Thanks

One just above the oil filter (screwed into the block) is the oil temperature sender which reads out on the digital dash.
There are two just to the driver's side of the distributor, near the firewall, screwed into the block as well.
One of them is the oil pressure sender which reads out on the digital dash
The other is a switch which will energize the fuel pump when it reads a certain oil pressure.
I'm sure on other year cars, they are different; GM "engineers . . . love to change things." (Dr. McCoy from Star Trek - The Motion Picture)

Re: Oil pressure switch/sender (JAKE)
BINGO !!! Right on, JAKE. Also in early 1984, there was only one "device" near the distributor. It had a 3 bladed connector and served the purpose of both the pressure sender, and the pressure switch for fuel pump . Late '84 and up, the oil pressure sender only has a two bladed connector, plus the switch. None of the devices, "sense flow". Only the pressure sending unit measures or senses the variable pressures. The switch only opens and closes at a predetermined pressure. The temp sensor only measures the the temperature. Good luck, and...
