What year model is the engine?

The best way to diagnose for an HPOP leak without a teardown: Remove the ICP sensor and use this hole to pressurize the HPO system with air. Remove the oil fill cap, remove the CCV hose that goes into the air intake from the other valve cover, take a piece of heater hose and listen in BOTH spots. If you hear air coming from either one it's probably a leak in one of the oil rails. If you hear air coming from BOTH sides it's probably the STC fitting or from the HPOP itself. The HPOP itself if virtually bulletproof on the 05-07 motors, but leaks can and do occur.

Beginning at apprx 40:00 minutes in the video below is some troubleshooting of the HPO system:
