Review on 🔧 Optimize Performance with High Volume Internal Oil Pump for GM LS-Series Engines by Cameron Novak

Very happy with it. My standard oil pump had a defective high-pressure bypass valve. I replaced it with this one. As expected, the oil pressure has improved. Hot idle 49 psi. The oil pressure at the top of the red line reaches approximately 110 psi. Stay away from cheap or flimsy filters as they can burst. It would be a good idea to do this job with an oil cooler check plate gasket. An older one may be prone to leaking due to the added pressure. I have no trouble vacuuming the sump dry.
