Oil pressure issues 6.0L Vortec LY6… SOLVED.

Vortec 6000 low oil pressure issue solved with a $2 gasket. The oil sump pick up tube o ring was flat and dried out… bought an oil pan gasket, which it already needed and the o ring… replaced them and life is good. Time to upgrade the mirrors, headlights, brakes and give her a massive detail.

Keep an eye on it, my o-ring was bad, replacing helped but ultimately it was the oil pump, relief valve went on it

Oil pump just went out on my 07 2500 HD yes it’s the oil pump not an O-ring. I completely agree with you replace the oil pump.

Just below the oil pump inside the oil pan.
