the motor in my gta was not equipped with an oil switch when it was built so I have to remove the SR to install one. Can I pull the intake off in one piece by removing the lower bolts going into the heads? Ive heard alot of people have problems with vacuum leaks when reinstalling the runners and upper plenum so if I can avoid taking apart the upper and runners I will.
I don't think you can... I haven't tried it, but I have had mine off 3 times, and I don't think it is going to happen... To prevent vacuum leaks, just use alot of RTV, that is what I do...

Im talking about the oil pressure sensor...... I looked at it closely today and I dont even think I could get the injector harness connectors off let alone the entire intake..... oh well it was a thought..
well if your looking to mount the oil pressure sending unit, it wouldn't go under the intake. Its mounted on the block itself. Drivers side just above the oil filter
the sensor above the filter is for the light (low oil) not the pressure. the pressure sensor for a guage is located on the rear of the block next to the distributor on the drivers side

your wrong..its the oil pressure sending unit...thats the only one! Your not going to find the one under the super ram because it doesnt exist
depend s on the year of the car 88 and up use 2 sensors 1 for the gauge behind manifold near the wall and drivers side is for the fuel pump bypass if your realy dies on the fuel pump but you could put the gauge along with the other one just t them off and extend the wire

Why do you keep saying under the superram? Its behind it, and your wrong by the way every trans am Ive had the oil pressure sensor is located next to the distributor.... Im not asking Im telling you
There are 2 sensors, a 1 prong type on the rear china wall of the block for the gauge, the other one is above the oil filter and is for the fuel pump relay, on later cars the 2 are integrated into a 3 prong model just above the oil filter. I think the change came with the speed density setup, not 100% sure but the 92 GTA has the 3 prong combo sensor

You are both wrong.
Some cars had one sensor, some cars had two. I've stripped a few dozen of these cars when I had my business.
Two side sensors are available, a 2-pin which just operates the fuel pump, and a 3 pin which operates the fuel pump AND provides a gauge signal on models that did not have the top sender. (i.e, my 88 TBI car, 91 TBI car, '89 formula 350 car).
I do recall stripping a few that had the gauge sender on the china wall, and a 2 pin sender on the side of the block but I can't for the life of me remember what years. They were earlier and less common.

My '88, and '91 was that way too. I think maybe the earlier cars, like pre 87 were wired that way. I know my 87 vette was.
every sbc Ive ever worked on had the oil sender on the top of the block in the rear,,, which imo would allow you the best point to guage if the oil pump is pushing the correct amount of pressure all the way to the top of the motor. Wouldnt a sensor at the oil filter be miss leading for oil pressure up to the heads? Anyway my 87 TA, 85 TA, and this 87GTA all have the sensor at the top of the block.
The vertical passage that is drilled into the rear china wall intersects with a horizontal main gallery straight from the oil filter and one below that straight from the pump (an inverse v shaped passage, one side drilled from the filter pad, the other from the rear main bore, intersecting with the vertical drilled feed hole under the cap), the 2 parts are separated by the so called hidden plug. This vertical passage extends into the port above the filter pad. As such, it registers the same pressure as when it would put it on the filter pad. There are plenty of factory applications with the pressure sender above the filter pad.
Check the drawing in the lower left corner...se where that vertical passage goes? it meets up w the rear china wall plug up top
