Review on 🚗 GM LS-Series Melling M295 Internal Oil Pump, Wet Sump (Standard Volume) - Each by Emanuel Guffey

The oil pump was as advertised, good value and worked as well as it could. My oil pressure was restored but I think the real problem was the o-ring on the intake manifold was very loose and sucked in air when cold, after the engine warmed up the oil pressure was decent but the new OIL PUMP increased that Print. about 20 pounds to 55 pounds per square inch. Personal note: The oil pan can be removed without lowering the front differential, an engine mount was used to raise the engine.
