Melling M295 Ls1 Oil

Melling Oil Pump Stock Pressure Stock Volume M295 Fits Gen III & IV 4.8 5.3 5.7 6.0 6.2 LS1 LS6 LS2 LS3 The Melling M295 pump is a standard pressure, standard volume pump that is considered a suitable replacement for the factory oil pump (GM part # 12586665) and offers improved resistance against cavitation at higher RPMs. The cast aluminum housing is CNC-machined and hardcoat anodized. The cast iron cover is CNC-machined and phosphate coated. The relief valve features a screw-in valve plug. The factory LS oil pump suffers from cavitation above 6,200 RPM, which results in a drop in oil flow of nearly 1 GPM by 7,000 RPM. This cavitation can also aerate the oil, which causes drops in oil pressure and can result in oil starvation. This is why we do not recommend shifting any higher than 6,200 RPM with a stock engine. Engines that run at RPM's above 6,200 should use an upgraded Melling pump to prevent these issues. Features: Factory volumetric flow rate, around 6.8 GPM The cast aluminum housing is CNC machined and hardcoat anodized The cast iron cover is CNC machined and phosphate coated. The cover also features countersunk screws for more timing cover clearance. The relief valve features a screw in valve plug with the optional lower stock pressure spring supplied Compatible with factory GM oil pickup tubes Fits GM GEN III & IV LS and Vortec Engines Without AFM/DOD Applications: Gen III LS blocks LS1, LS6 Gen IV LS blocks LS2, LS3 Gen III Vortec 4800 LR4, LM7 Gen III Vortec 5300 LM7, L59, LM4, L33 Gen III Vortec 6000 LQ4, LQ9 Gen IV Vortec 4800 LY2, L20 Gen IV Vortec 5300 LH8, LH9 Gen IV Vortec 6000 L98, L96, LY6, L9H Gen IV Vortec 6200 L92, L9H This pump is not compatible with engines equipped with the AFM or displacement on demand.
