Diesel Performance Head Gaskets
Head gaskets have a tough job sealing combustion pressures in diesel engines because of their high compression ratios and boost pressures. Diesel engines are typically low revving, high torque motors that are designed to last several hundred thousand miles.
Air Filter Show & Tell: Seeing Is Believing
Air filters are normal wear items that require regular checks and replacement. Their role is to trap dirt particles that can cause damage to engine cylinders, walls, pistons and piston rings. In fuel-injected vehicles, the air filter also plays a role in keeping contaminants off the airflow sensor.

Porsche Announces New 4-Cyl Boxer Engine
Porsche’s decision to develop a new four-cylinder engine stems from its need to improve fuel efficiency and emissions ratings across its model line. The new engine will come standard in the Boxster and Cayman models. There has been talk of a four-cylinder 911, but that’s rather unlikely. The new engine features a horizontally opposed, “boxer”
Venturing Into Duramax Territory
Back in the 1990s, GM wasn’t making too many waves in the diesel truck market. The 6.2L and 6.5L engines had been around for sometime, but they were no match for the release of the Cummins 6BT in the Dodge truck in 1989 and the Ford Powerstroke in 1994. GM never really had a strong

Hybrid Data PIDS Tech Tip
In this hybrid vehicle tech tip Dave Hobbs talks about an ‘engine stop request code. If you’ve got a hybrid vehicle and you’re not sure– is it doing an idle stop or is it just stalling– because we have still have an internal combustion engine and that means we still have all other kinds of sensors that can cause drivability issues, including intermittent stalling conditions. Thats why Dave talks about the engine stop request PID and how it can keep you from chasing the boogeyman.

Special Report: Alternative Fuel: Diesel Vehicles Available in the U.S.
In 2008, 12 auto manufacturers have announced or introduced at least 13 diesel models to the U.S. market and unveiled four concept cars with a diesel powertrain. Thus, the growing resurgence of clean diesel technology in the U.S., coupled with the additional environmental and economic benefits of biodiesel, are giving American consumers more options to “drive green” than ever before.
According to the Alliance of Automobile Manufacturers, there are now more than 4.8 million diesel cars, pickups and SUVs registered in the United States.
Most analysts expect continued growth in the diesel market. Researchers at J.D. Power and Associates predict that diesel sales will approximately triple in the next 10 years, accounting for more than 10 percent of U.S. vehicle sales by 2015 – up from 3.6 percent in 2005.
