Melling 10355HV LS Oil Pump 20% Higher Volume, 10% Higher Pressure Suitable for VE VF Holden Commodore & HSV L76 L77 LSA Engines. Melling Select Performance has been manufacturing and providing cutting edge performance engine parts for over 65 years. One of the most trusted names in the business, this is a direct high volume, high pressure replacement for your factory oil pump.
The Melling 10355HV oil pump is a high volume, high pressure oil pump that 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 oil pump. Engines that run at RPM's above 6,200 should use an upgraded Melling pump to prevent these issues.
The pumps are built using a proprietary casting process, which yields maximum performance and reliability. Every Melling oil pump is completely pressure-tested, including idle and bypass pressure, before it leaves the factory. This makes the Melling 10355HV oil pump a perfect addition to any camshaft upgrade or simply as a serviceable replacement - all whilst remaining incredibly cost effective and very simple to install. The Melling 10355HV oil pump is an excellent upgrade for the factory GM high-flow oil pump.These pumps flow more fluid than most standard LS pumps and Melling M295/M365 pumps to accommodate Active Fuel Management (AFM), also known as Displacement On Demand (DOD). The additional oil volume can improve engine lubrication and is considered a suitable performance upgrade for LS engines still using AFM/DOD with larger capacity oil pans.
Issues often become apparent when removing your old oil pump when working on your engine. Remove this risk and replace your worn-out unit with this high quality, high pressure oil pump and feel assured your engine is getting the oil it needs for many years to come. This oil pump also includes 2 pick-up O-rings. The thicker green O-ring is to be used on a pick-up tube that has a recess in it for a captured O-ring seal, whereas the black O-ring is suitable for a more traditional style pick-up tube. Both are included to ensure you have the correct seal for your application.
