My high volume pump runs 75 psi at start up as it is sucking 10W40 from an 8 quart pan...What's wrong with 70 +psi? Perfectly normal for a High volume pump.
Well, since it's now apart......I have never in my time as a mechanic heard valvetrain do that and still have oil pressure that consistent, so I knew it wasn't in that part. What RPM's did you hit?
