Yes it was a fresh build. Had oiling mods done in the block when I had it rebuilt. Oil pressure didn’t run that low before and the changes in the rebuild were lifters and the oiling mod. So one of the two caused the oil pressure to be lower at idle than before I suspect. When it’s cold, idle is around 30 or 40 I think. It’s been a while since I’ve looked at it cold so don’t quote me on that. But I raised this concern to the engine builder. He didn’t particularly like that it was that low but he also said that it wasn’t a concern if it was only that low at idle. He was more concerned with the pressure at mid to WOT which it stays around 60-70 psi hot. It’s made around 20-25 passes and the rest us been street driving. But even street driving she’s hitting 7200 rpm frequently. Have checked the bearings and they looked great. So the low oil pressure at idle no longer bothers me. It has good oil pressure where it counts and that’s good enough for me.
