Oil Pressure Sensor Relocation

Oil Pressure Sensor Relocation Kit

But why?

The C5's oil pressure sending unit/sensor is really good at randomly ceasing function. Unfortunately, it's kind of a pain in the ass to get to. With a relocation kit, you only have to go through that pain once!

These parts should be listed in their order of assembly.

Wouldn't hurt to double check my parts list, either! Just make sure all the male to female and vise versa make sense. AN to AN, etc.

Tools I strongly suggest using/buying just for this job

1. 1-1/16" Oil pressure sensor socket - Your auto parts store of choice!
2. Teflon tape

Instructions

The instructions are pretty bare bones here, there are lots of YouTube videos that go over this process fairly well. Just search "c5 corvette intake manifold removal" and a good one should pop up. I'll write down the general instructions here though.

1. Pop the hood
2. Maybe lift your car? You won't have to bend over as much, but it's not necessary. Do it safely!
3. Remove the spark plug boots from all of the spark plugs. Just leave them attached to the coils.
4. Remove the ignition coils by undoing all the small bolts that hold them to the valve covers. Also unplug all of your fuel injectors!
5. Loosen/remove the hose clamp that fastens the intake to the throttle body. It's really best to just move this out of the way.
6. Loosen/remove all the bolts that fasten the intake to the motor. The 2 bolts closest to the firewall are a bit tricky, a ratcheting wrench or low profile ratchet is your friend here.
7. Remove any other hose or wire connections from the intake... there are some miscellaneous emissions (I think) connections on the driver's side, flexible fuel line running to the rail, and I think there are also coolant tubes connected to the throttle body. Might depend on the year of your car!
8. Another pair of hands here would be helpful. You're gonna have to lift the intake and pull the rear most captured bolts up as far as possible, until you can wiggle the intake out, and the bolts are freed.
9. Using your special socket, gently loosen and undo the old oil pressure sensor. Make sure to unplug it first. By the way, don't drop anything down into the hole once the sensor is removed.
10. Cleaned up the area a bit with a non-linting rag or towel, and some solvent.
11. Go ahead and install the metric adapter (M16x1.5 to 1/8 NPT), make sure the copper crush washer is installed with it! Also, I'm not sure what the torque rating is, but don't go gorilla mode on it. You really don't want to strip these threads.
12. Next, apply some teflon tape to the male NPT threads and install it into the adapter in the block. Same tightening methodology as above. This one is a little more tricky as it's got a 45* angle, so just get it tight/sealed in a good spot that generally allows the hose to go around the intake and coils.
13. Next is the hose, followed by the Summit AN reducer, then the Redhorse reducer, then the oil pressure sensor itself. Make sure all of these are nice and tight, but not crazy tight!
14. Reassemble everything, and make sure the sensor is plugged into the harness. Start your car and check for leaks, and a functional oil pressure gauge.
