2006 Silverado Noisy, Low Oil Pressure

Asked by Aug 22, 2017 at 04:45 PM

Question type: Maintenance & Repair

Recently bought a 2006 Silverado with a 4.8 v8.
The truck starts at 40 psi of oil presume when cold,
then makes its way down to just above 20psi.
Makes a ticking noise that seems to be louder
under the motor than over so I'm not sure if it's a
valvetrain noise. Not driving it for now just I'm
case. It's a 4x4 so I'm not looking forward to taking
down the oil pan if need be in order to change the
pump, but I do have one already. Thanks
