I think they only run at half a bar of oil pressure, there should be a plug there.. If you've got a oil pressure gauge then it shouldn't matter but don't quote me on it. Welshpug will have more info about it.

Where abouts on the engine was it?

There should be one just above where the heat exchanger sits, I believe thats for the low pressure light and it should have a plug from the loom on it.
Off to the right of this (just left of where the small breather pipe goes into the block) theres a port which i've found on some previous engines has had a sensor in it's place to seal it but no connector should go to this one.

right next to the oil breather t peice underneath the inlet manifold. i think where/what you are describing with the small breahter pipe into the block.

grey 2 pin plug (i think, was very dirty) went and had a google, found the ubiquitous picture of the colour coded engine block sensors

red - oil pressure warning switch.

Some use two sensors, one is just a blank.

Both the red and the pink (205 drivers link) are oil pressure and can be used.
