Low oil pressure after lifter release and VLOM modify
i have a 2014 Silverado with 5.3L AFM and after releasing the lifter and completing the VLOM modification. It worked but now the Oil pressure is around 15psI. I also replaced the fuel pump, fuel injectors w/rail, PCV valve and oil pressure sensor. Any suggestions?

Well, the VLOM only flows oil during AFM activation. However, that part where the sensor is plugged into actually goes into the main oil galley at the top of the engine. This is so that I can read engine oil pressure and the part the vlom plug blocks off, is the part that feeds from the main oil galley to the solenoids in the VLOM.
