  1. A bit of topic I know but, on a cross country several years ago in a constant speed machine I suddenly lost oil pressure - it was reading zero by the time it was noticed. I reduced power, bought the pitch back to full fine and started looking for a suitable field. Every 15 - 20 seconds the oil pressure flickered and rose to about normal and then dropped back to zero just as quickly as it came up. I turned for home and nursed the engine at low rpm heading back to the closest airfield, all the time looking for a more suitable forced landing area. Although I lost some altitude, I managed to make it back the the departure airfied and landed safely. The aircraft flew for over 20 mins in this state. On the ground, the covers came off and we discovered a broken flare on the propeller governor oil line running from the rear to the front of the engine. In this case an IO-360 Lycoming. It seems that with the prop in full fine (on this engine at least), there is no pressure in the governor line, so no more oil was lost after full fine was selected. There must have been just enough oil left in the sump to intermittently allow the pump to push a bit out as it returned from the engine. I know that some constant speed prop's will go to feather when they lose oil pressure, but some don't - check your machine, know your machine and this little tip might save your engine or your life one day.
