Ford 5.4L Internal Oil Pressure Leak Diagnosis

My technique used to determine erratic oil pressure problem in Ford 5.4L. I ended up dressing the front of the motor (tensioners, chains, guides, phasers, HV oil pump) and my original problem shown in my other video is solved. I feel I could have probably been cheap and just hung tensioners, but I plan on keeping the vehicle long term so the correct fix was applied. I'm thinking the leak had the oil pressure right at the edge of failure and when the VCT system was applied it drew too much volume away from the already compromised system. Additional bonus is that this diagnosis helped to ensure there weren't other problems before investing $850 in timing related parts.
