Coolant PSI Question.

For those that are familiar with the coolant PSI gauge and using it to test for blown headgaskets or ruptured egr cooler, here's my scenario.

I let the truck come up to operating temp in my driveway - PSI gauge reads 3 - 4 range. (EOT 196)

I drive 1 mile to the freeway on ramp and from there drive 5 miles up a moderate grade at 75-80 MPH - PSI is 7-8 range. (EOT 198-200)

I turn around and come back down 5 miles into town. Doing a few WOT runs up to 90MPH - PSI is 6-7 range. (EOT 196-198)

Once in town I go 2 miles up steep hill at 30-35MPH - PSI gauge reads 10. (EOT is at it's highest point of 206)

Once in the drive way, truck shut of the PSI Gauge will drop 5 PSI in one hour.

I have a new BPD EGR cooler, so that can be eliminated.
