Don't rule out the head gasket. Those things can leak ever-so sightly and not cause any other issues. Remember, on a turbo car, you're pumping pressure into the cylinders while combusting fuel.

The oil pressure sensor is located on the back side of the engine about 1/2 up the block, dead center. It's close to the starter. It should have 1 wire connected to it.

When you mention the clutch, it makes me wonder what you are leaking. Are you leaking brake fluid, oil, transmission fluid, coolant, or maybe even power steering fluid. If we open the search up to all of those things, a common culprit would be the power steering lines which run in that general area on the back of the engine.

I suggest buying about 2 cans of engine degreaser and 1 can of brake cleaner. After you get through both cans of degreaser, use the entire can of brake cleaner and then towel-dry everything off as best you can. then with your car on jack stands, start it up and get under it with a flashlight. You should be able to pinpoint the start of a leak pretty quickly if it's leaking enough to drip onto the cat.

Good luck
