I'd check the pressure pressure gauge and sender as well as the electrical connections and grounds. If you can't solve the problem that way, try an after-market oil pressure gauge, if for no other reason than to see if you really DO have an over-pressure condition.
Note, if the oil pressure really is that high it's caused by a sticking regulator. You'll need to pull the pan and get into the regulator assembly to find why it's sticking.

Chevy Venture brake line leaking?
When a brake line is leaking on the Chevy Venture the brake line should be replaced as soon as possible. A leak, however small, can cause hydraulic fluid to escape the brake line which will cause a loss in brake pressure. The brakes should be bled of air after the new line is put in to remove gaps in brake pedal pressure.
