Oil pressure (as measured on my Dynon Skyview) went to zero last evening on the ground while testing the installation of my new CS prop. I had done a couple of run ups, exercised the prop, etc and then got a warning from Skyview. I taxied the 200 yards back to the hangar while watching the oil temps and CHTs. By the time I got there, the indicated pressure was zero and I shut down quickly. Oil temps and CHTs were all about what they were before the warning (121F for oil, mid 300s for CHT), so in looking for corroborating information that I really had an oil pressure problem, I wasn't able to find it.
No oil loss, no oil leaks, dry as a bone FWF. I did do an oil change very recently and had 7 qts in the engine. I send oil samples to Blackstone at every change and I had a great report from them on this change. The engine has about 200 hours on it, a Titan IOX-370.
So, need a plan to figure out what's happening. One obvious possibility is a bad oil pressure sensor (it's the Kavlico sold by Dynon). So, plumbing in a mechanical gauge makes sense and then I'd remove the top plugs and run the starter with ignition off to see if I get a pressure indication. Another idea is to remove the oil pressure line and fitting to check for obstruction. If none of these point to the answer, what's next (other than a teardown)? Ideas?
