I started up my 0-320 this am and noticed that my Vans oil pressure guage registered 0 zero. I waited for it to respond and nothing for longer than I felt comfortable. I shut down and looked around the engine, checked sensor connection, already knew I had oil and looked for other evidence of leak or some type of problem. Nothing. Got back in and restarted. Oil pressure within seconds went to safe limits. Only difference was the first start took about 4 trys due to cold conditions. It was about 38 degrees. Anyone have an explanation for the lack of oil pressure registering on the guage on the first start and not the second. I monitored the guage during flight and it was in the green all the way. thanks, Jack
