Can someone ID this part?
Hi, I have had an oil leak that keeps getting worse. This spring I am getting 20 drops a minute. I cleaned the bottom of the engine and followed the stream up to the left of the air cleaner box and found this down in behind an oil hose. It looks like maybe an oil pressure switch leaking? A tight space to get into. Does the engine need to be dropped to fix? Thanks!

If you can see it, then I'm guessing you have a 3.2 911, not an SC.
That is the oil pressure warning light switch, and when the crimp starts to give way, you end up with a gusher of oil on your hot exhaust pipe. If it's a 3.2, then you are looking at a 30-minute job even if the motor is hot. If an SC, then it's an all day job at best.

OK, cross-posted.
Remove the air box, and air flow meter "flapper" box. Take care to not break the plastic connectors.
Use a socket wrench. I want to say 24mm (?) to remove the old one and install new.
You should also probably change the oil thermostat o-ring. Buy the green one (viton). You may need a small right-angle screwdriver to pry it out. Very easy job.
Tip: If you have the stock AC, remove the compressor and place it on top of the right side intake. This will allow you to have easy access to the air box clips to undo the lid.

Once the airbox and air flow meter are removed, use a strong flashlight, and stick your head in there sideways, then look down on to the motor. Use care not to bend the engine harness wires too much.

Next to the leaking oil pressure warning switch. Little oval plate held on with two nuts. See this image, to the right of the oil pressure warning switch:

If you unbolt it and lift it out, you'll find the engine oil thermostat (Part 35 in Steve's diagram) that is sealed by an o-ring. Often leaks, so if you're already back there, worth replacing.

Thanks guys....I just had this in the garage and they couldn't find the leak....said the engine would need to be pulled as it was leaking on top somewhere. Hard to find someone around here (NE PA) to work on these that knows what they're doing. You guys are lifesavers. I got the airbox and air flow meter out. My buddy thinks he has a 24MM socket....can I order the switch, and O-ring, from a local parts store?
