Exploring The GM Duramax High Pressure Oil Pump

The oil pump in a GM Duramax engine draws lubricant from the pan and sends it flowing around the briskly moving internals. The oil travels through specially designed passageways called oil galleries. The purpose of the oil is to cool down the moving parts and keep friction to a minimum. A properly working high-pressure pump will keep engine internals alive and functioning correctly for several hundred thousand miles.

Components and Functions

The inside of the oil pump is a simple mix of gears, bolts, nuts and an outer casing. Since the pump sits in the lubricant filled oil pan, there is little chance of rust or corrosion weakening the metal outer case. A high-pressure oil pump uses drive gears to create pressure in the system. The pressure pulls oil up out of the pan at the bottom of the engine and sends it clear up to the heads up top.

Common Problems

The GM engine requires frequent oil changes to keep the fluid from thickening and clogging up the lines. When the oil filter goes bad, it could release dirt and metal shavings collected from the engine into the oil pan reservoir. If this happens, the high-pressure pump will suck up these contaminants and send them back through the oil galleries. When quick moving internal components do not receive the proper amount of oil, the parts could overheat or seize together. The result is a loss of power or an engine that will not even crank over.

If the pump sucks up any substantial contaminants, the teeth on the pump’s gears could snap right off. The broken teeth reduce the pump’s ability to send oil through the system, resulting in sudden fluid starvation. Furthermore, the teeth could jam into the remainder of the moving gears and stop the pump altogether. Once the pump stops working, the GM vehicle will send a fault warning to the dash lights to alert the driver. The engine must be switched off at once to protect the rest of the internals from costly damage.

Dodge Cummins High Pressure Oil Pump

The Dodge Cummins is considered a great, reliable engine that has always had a reputation as hard working piece of machinery. The Dodge Cummins requires proper functioning of the of the oil pump so that it can deliver the perfect type of pressure so that oil can be delivered across the engine. If the pump is not functioning and the pressure is not at good levels problems can occur in the engine. There are certain sign you can watch for that will signal when the oil pump is not operating at his best.

One of the first signals, like with many problems will be the service engine light alerting you. This lets you know that the pressure is not high enough. A service engine light can mean that the engine is leaking oil. It can also mean that it has burned oil faster than is required. When there is a reduction in pressure the oil will not lubricate properly. Ignoring these signs could lead to overheating. Because the Dodge Cummins is a tough engine but it does require that oil be plenty high enough so that the oil is delivered to the engine bearings. When this is not happening you might hear a strange start sound.

  • Do not underestimate the importance of the high pressure oil pump in your Dodge Cummins engine. It is an important device which is repsonible for vital systems to work right. As the engine ages it is very important to keep a close check on oil levels.Dog

Ford Car Seats that Detect Heart Attacks


Things are getting pretty interesting at Ford Motor Company. Ford’s European Research and Innovation Center is working on a car seat that can detect heart attacks by monitoring heart activity. More info via The Daily Mail:The Daily Mail:

The Ford heart rate monitoring seat performs much like a traditional ECG, except the sensors are placed on the surface of the car seat instead of being directly attached to the driver.

These special sensors are capable of reading the heart’s electrical impulses through clothing and are able to use the driver’s natural contact with the seat to maintain a reading in most cases.

Ford expects the seats should be available by 2020.

Dodge Cummins – Don’t underestimate the importance of a high pressure oil pump

The Dodge Cummins is a strong and reliable engine that has a reputation for being a mighty work-horse. This engine, like most, require that the oil pump function properly and deliver the right type of pressure to deliver oil across the engine. When the pump is not function or pressure is not at optimum levels it can cause major problems to the engine. There are some typical signs to be aware of when the oil pump is not operating correctly.

Like with many issues going on in the car, a service engine light will activate when the pressure is not high enough. Hopefully you do not fall in the category of a driver that ignores that light, and places duck tape over it. A low pressure alert could mean that your engine is leaking oil or burning oil at a faster rate than necessary. This reduction in pressure means that oil will not lubricate the vehicle appropriately. This could lead to issues like over heating that can destroy the engine if left unchecked.

It is always important that the driver be aware of the sounds and feel of the drive. In many cases, when the oil pump is not working well the care begins to make a noise or the vehicle is just not driving a smoothly as it once did – each are reason to check the oil pump. The Dodge Cummins are tough engines and require that the oil pressure be high enough to deliver oil to the engine bearings as well as insure the car starts properly. If you are noticing a cranky start and might be a pressure issue that is not necessary a bad starter in the car.

The importance of a high pressure oil pump in the Dodge Cummins engine should never be underestimated. This is an integral device and functionality to the car, responsible for several vital systems working correctly. Just like the human body, in an engine all the parts rely on one another to keep the whole working well. There is no part that deserves to be ignored, especially the high pressure oil pump. Make sure to always check your oil as the engine ages to make sure you are not loosing oil through a leak, these changes in pressure will cause larger issues. As parts do not receive the correct lubrication friction and heat build to erode parts and function quickly.high pressure oil pump in the Dodge Cummins engine should never be underestimated.

3 Benefits Of A High Pressure Oil Pump In A Duramax

General Motor’s 6.6-liter Duramax diesel engine greatly benefits from the inclusion of a high-pressure oil pump in the lower pan. The sheer size of this engine demands the use of pressure to push heavy oil through the system. Otherwise, the engine would suffer from poor flow that could lead to overheating, which in turn, damages the bearings and other internal components. Read on to learn about the benefits of including a high-pressure oil pump in the build.

Improves Lubricant Flow

The oil pump pulls lubricant from the reservoir and feeds it through the galleys to send fluids throughout the entire engine. Since the moving internal parts rotate at several thousand RPMs, it’s important for them to maintain a layer of lubricant.

If the oil pump cannot transport the fluid into the entire engine, internal parts will wear down incredibly quickly. A high-pressure pump makes sure the oil shoots all the way through the engine to the heads at the top. This keeps everything from the crank to the camshafts in perfect shape.

Reduces Heat Production

Oil reduces friction between moving parts by lubricating their external surfaces. Reduced friction allows the engine to operate at a lower temperature, which protects both moving and stationary parts inside the engine.

If oil sits at a high temperature for an extended period of time, the seals and gaskets could fail prematurely. Furthermore, sensitive metal parts, such as the aluminum heads, could warp out of shape from the high temperatures. A high-pressure oil pump quickly cools the oil and sends it back through the engine for another pass.

Extends Bearing Life

The Duramax engine uses a series of bearings to support rotating parts, such as the crank and camshafts. These bearings are made out of a thin piece of metal that sits in the supportive cutout in the block and head. In the center of each bearing is a small oil galley that allows lubricant to shoot through onto the bearing surface to reduce wear on the moving parts.

If the bearings wear too early, the rotating parts could end up gouged or even warped. The high-pressure pump ensures all of the bearings receive an equal amount of lubricant to keep the metal from wearing away prematurely.

In the end, the oil pump protects the Duramax engine in so many ways; it’s hard to imagine this build without it.

GM’s New Self-Driving Cadillac

In the near future, General Motors expects to start selling a Cadillac vehicle that can drive itself. This luxury car could be on America’s roads by the summer of 2016. The company’s CEO recently revealed these plans during a speech that she delivered at Detroit’s Intelligent Transport Society.

Super Cruise

Speaking to ITS World Congress attendees, Mary Barra explained that an unnamed 2017 model will feature an advanced form of cruise control. The system enables a vehicle to intelligently operate its own brakes and accelerator during traffic jams and highway travel. She predicted that a fully self-driving auto might be available by 2020.

The Super Cruise system was first demonstrated about two years ago. It won’t allow drivers to safely fall asleep or watch movies behind the wheel. Motorists would have to remain aware of road conditions and take control when the situation becomes too complex for the automobile.

V2V Technology

Barra also announced that the 2017 model of the Cadillac CTS sedan will feature a new vehicle-to-vehicle communications system. The V2V technology enables a car to gather data from other nearby autos and use it to warn drivers about oncoming hazards. Cars with this feature share information on their current speeds and locations.

The system could help Cadillac develop more sophisticated self-driving autos that can adapt to urban conditions. However, this capability won’t be very useful to computerized or human drivers until a significant number of vehicles feature it. Other automakers have yet to announce specific plans to incorporate V2V technology.


Although it may take a number of years for automakers to develop cars that safely automate all driving, impressive progress toward this goal has been achieved in recent years. Bloomberg reports that certain Acura models automatically apply their brakes when the next car travels at a slower speed.

As GM’s CEO pointed out in her speech, completely automated vehicles already exist but aren’t for sale. A computer-driven Chevrolet Tahoe successfully traveled 60 miles in 2007, making its way through intersections and traffic. However, automakers still need to enhance and verify the safety of such vehicles before the public can use them.

Ford Releases more info on 2015 F-450

Straight from the horses mouth, we wanted to share this press release from Ford about the revamped F-450.


  • For customers who require no-compromise towing capability, the 2015 Ford F-450 Super Duty Class 3 pickup boasts the highest rating of any pickup truck in the United States – 31,200 pounds, measured using the Society of Automotive Engineers J2807 standard
  • F-450 Super Duty towing capability is 2,200 pounds greater than its closest competitor’s crew cab 4×4 pickup truck
  • Ford will rate 2015 F-Series Super Duty maximum payload using base curb weight, aligning its payload rating practices with other manufacturers to make it easier for customers to compare vehicles

Ford reaffirms the undisputed heavy-duty towing leadership of the 2015 Ford F-450 Super Duty Class 3 pickup at 31,200 pounds after testing using the Society of Automotive Engineers J2807 standard.

SAE J2807 establishes tow vehicle performance requirements against certain performance criteria to determine a truck’s maximum trailer tow rating. Ford is a founding member of the J2807 committee, which includes other truck and trailer manufacturers.

“We leave no doubt with customers that the F-450 pickup truck has best-in-class towing of 31,200 pounds – whether tested using our own internal towing standards or SAE J2807,” said Raj Nair, Ford group vice president, Global Product Development.

2015 Ford F-450 upgrades
Ford improved the 2015 F-450 pickup by giving it a more capable version of the F-350 frame, plus a more capable suspension and 19.5-inch wheels and tires to enable its best-in-class towing.

The F-450 pickup is available exclusively as a crew cab 4×4. The truck’s J2807-certified maximum tow rating is 2,200 pounds greater than its closest competitor’s crew cab 4×4 pickup.

Best-in-class towing performance is achieved with Ford’s second-generation 6.7-liter Power Stroke® V8 turbo diesel engine that has been developed to provide the segment’s top combination of power, torque and efficiency. The Power Stroke boasts best-in-class 440 horsepower across all Super Duty pickup models – from F-250 to F-450. Super Duty also offers 860 lb.-ft. of torque for the same models.

Ford is the only heavy-duty pickup truck manufacturer that designs and builds its own diesel engine and transmission combination – from concept to execution – ensuring the powertrain will work seamlessly with all chassis components and vehicle calibrations. This approach enables Ford engineers to optimize the vehicle’s performance across the entire lineup.

Ford previously determined F-450 pickup towing capacity using rigorous internal testing standards exclusively. Now it has added SAE J2807 test procedures, reaffirming the F-450 pickup rating. F-450 passed the additional tests with 31,200 pounds in tow, just as it passed Ford internal tests.

SAE J2807 requires the vehicle to be loaded with about 400 pounds more weight than Ford’s internal test (two passengers instead of one, and base curb weight instead of minimum curb weight), but the weight addition has no effect on F-450 towing capacity. Using either standard, F-450 has best-in-class towing capacity of 31,200 pounds.

As a result of the J2807 test results, Ford is also increasing the F-450 pickup’s already best-in-class gross combined weight rating from 40,000 pounds to 40,400 pounds – topping the nearest competitor by 2,500 pounds

Payload rating changes
Ford is migrating to the J2807 standard when it introduces all-new vehicles and will use base curb weight, rather than minimum curb weight, to determine payload ratings for all of its pickup trucks. The change will align Ford’s payload rating practices with other manufacturers to make it easier for customers to compare vehicles.

Using base curb weight, maximum payload for the 2015 F-450 pickup goes from 5,450 pounds to 5,300 pounds.

As always, actual payload ratings are determined for an individual vehicle in its as-built condition at the factory. Ford F-Series Super Duty customers continue to have the flexibility to add or delete equipment to meet their specific payload needs. Each truck’s unique payload rating can be found on the tire and loading label on the door frame.
