Risk vs. Reward: When it Comes to Oil Pumps, Knowing Whether to Reuse, Rebuild or Replace Can Be a High Pressure Proposition

Most engine builders appreciate how important good oil pressure is for proper engine lubrication and longevity. They also know that low oil pressure can cause engine noise, bearing failures and customer complaints that result in an expensive warranty claim.

Wet & Dry Sump Oiling Systems – Choosing the Right System for the Right Job

If you are building a customer’s “dream engine” what type of oiling system should you use? The answer to that question will depend on the application (street, drag, circle track, road race, off-road or marine), engine RPM and how much your customer is willing to invest in a lubrication system. Your choices may also be

The Science Behind Wet Sump Oil Pumps & Oiling System Upgrades

All automotive internal combustion engines are equipped with some type of pressurized oiling system. Oil lubrication is essential for reducing friction, preventing wear and cooling vital engine components. Pumping oil to the main and rod bearings creates a friction-reducing hydrodynamic film between the bearings and crank that allows the crank to spin with minimal friction.

PERA to Host Webinar on Oil Pumps

This presentation will review late model crankshaft driven oil pumps and how they compare to traditional camshaft driven oil pumps. It will also cover the pros and cons of their design along with failure modes and other issues experienced in the field.

Oil Pump Pressure vs. Flow

Melling technical director George Richmond talks about the difference between pressure and flow within an oil pump.

Melling Shark Tooth Billet Oil Pumps

Melling Shark Tooth Billet oil pumps utilize an exclusive helical asymmetrical steel gear design which improves the operation of the distributor resulting in less spark scatter and wear on the drive gear.

Choosing the Right Oil Pump

Choosing a replacement oil pump for an engine you are building or modifying is a process that requires some thought. Original equipment oil pumps are usually adequate for most stock applications – but some are not, especially if an engine is being modified.

Schumann’s Puts Wet Sump Oil Pump Program Up for Sale

Verne Schumann has been around racing since the mid-‘50s. He knows a thing or two about the industry and so does his business, Schumann’s Sales & Service, Inc., an engine parts supplier located in Blue Grass, IA, which Verne founded in 1970. Now, nearly 45 years later, Verne and his wife are beginning to ponder

Front-Mounted Oil Pumps: Good or Troublesome?

On late model engines such as Chevy LS, Ford modular V8s and Chrysler 5.7/6.1/6.4L Hemis, engineers have moved the oil pump from its cozy location inside the oil pan to the front of the engine under the timing cover. Traditionally, most wet sump oil pumps have been mounted under the engine inside the oil pan
