Got a 5.3 2013 suburban oil 10 psi at idle and 20 with throttle. Not major ticking or knocking. Changed oil psi sending unit and screen, reading manual guage. I was told it's possible I might have a bad vlom and only need to change that and intake gaskets, before wasting time on that is there any way to test the vlom?any help would be appreciated.
