Quote: Is it just me or this a common thing... everytime I do an oil change on the 400 it seems to take forever to get oil pressure. I had the truck run twice for about 30 seconds each time (after changing the oil) and I still have no pressure... I'd hate to run too long without knowing for sure...
Sounds like it's loosing prime. My 496 did this once and while after an oil change and prolonged drain. So far the Hemi hasn't done this.
