So I bought a 6ft finish mower and after replacing the coil had a good time mowing. I was about an hour into mowing I glanced down at the oil pressure gauge and was shocked to see it either 0 or really close. I instantly put in the clutch, engine revs up without load, I go to push the kill switch and the oil pressure jumps right back to 10lbs where it had been constant since warming up. At this point I am thinking it was a fluke so some sort so I turn around to make one last pass on the way back to put the tractor in the shop. I get 30feet and the oil pressure reads 0 ish again. same thing happens.. This time, I disengage the PTO and put it in 3rd gear and went straight to the shop. I checked the oil and it was at the bottom of run, so I will be adding some, but that shouldn't be low enough to cause a loss of oil pressure.
I recently changed the gauge. The old gauge would always show pressure immediately, sometimes while cranking. The new gauge from time to time takes a second or 2 to show pressure.
So my questions are.
Is there anything inside the engine that could cause this?
If it were a bearing spinning, I would think the oil pressure wouldn't come back. I mean what are the odds that it lines back up after spinning..
Is it more likely that my new gauge is faulty?
Should I be asking any other questions?
