I have an OM617 with 0 oil pressure. It still runs. I'm not sure that I'd trust if I fixed the oil pressure problem (which is why I'm pulling the injectors and calling it a day). It "lost oil pressure on the highway" and the previous owner had it towed home. The oil pan is smashed in and the cam is dry. I suspect that he hit something just before he lost pressure although he doesn't seem to think so.

For that period of time, don't worry about it.
