Couldn't find an answer for this. I recently had my oil pressure peg in flight. My oil pressure sensor is VDO and remote driving a GRT 2000 EIS. I vaguely remembered that air in the line could cause this so I bled the sensor feed line and the pressure returned to normal. (It seemed like there was air in the line when I bled it.) Then it climbed again, but did not peg. I bled it again and it returned to normal. Questions:
  1. Does this sound like normal behavior for the gauge? Would air in the line cause it to peg?
  2. I recently did an oil change so I'm hoping the air came from that. However, is it reasonable that I would be getting air some hours after the change, and not right after?
  3. My Kitfox has the oil cooler on the suction side of the oil system, between the tank and engine. Is it likely or possible I have a crack somewhere in that system that's drawing air? And if I did, would it be reasonable that said crack would never leak oil, since I have no visible oil leaks?

Thanks,

Hi Guy,

This doesn't sound like air. it looks to be more sender caused. It could also be a bad ground not making good contact. These two items are the most common causes.
