New crate motor woes

I performed the procedure to check for an intake leak this weekend. I removed the breather and the plug from the valve cover on right side of the car and used duct tape to seal the holes. I then removed the PCV valve and covered the opening. I the put the Vacuum gauge on the valve cover PVC grommet and started the motor. The vacuum gauge registered 1 psi of pressure and began rising slowly. The duct tape was also bulging on the other valve cover. As the engine warmed up the pressure stropped rising and settled at about ½ psi (after pressure was relieved). At no time was a vacuum ever registered and I do not believe the crate motor has an intake leak; the good news is that I didn't consume oil on the drive to the MoPar Alley car show (30 miles round trip) last weekend. Thanks again to Guitar Jones for the procedure, I guess I will watch and wait.
