Although I have never lost oil pressure to the extent you did, the vernitherm valve on my rear engine was not safetied by Continental, and the valve worked its way loose, causing an "oil paint job" as Chachi put it. I had oil pressure the whole time though. I have EI voice annunciator system connected to oil pressure probes (as well as other things). They are checked every time I shut down, when Stephanie (name of woman who recorded the messages) says "Check oil pressure".
