Hey guys, so I finally got a break from the wife's ToDo list and installed my AmsOil Bypass kit and put in AmsOil full synthetic 5w-40. After getting everything installed and filled up I took it for a drive. About a mile down the road I start to hear what sounds like a pump hum that changes with the rpm. Its really noticeable at lower rpms when my oil pressure is down around 30. At increased rpm my oil pressure seams normal, around 60. I have checked my oil levels, all fine. I tried finding the noise but cant due to the engine noise, I only seem to be able to hear it from inside the cab. Anybody got any ideas, and should I be worried?
