This engine was rebuilt around 2000 miles ago. On a completely cold start, oil pressure is around 100, sometimes 100+ (In this video, car was very slightly warm so it didn't hit 100). Once warmed up, however, everything is fine and within specification. But should my oil pressure be 80+ at 4500 rpms+? It doesn't seem right. I have no other issues with the car though, besides the fact that it doesn't like to move when it's cold (leans out, bogs down, backfires) I am using Mobil 1 5W-40.
Any thoughts as to what it could be?
