Memory Lane: Culture Club – Restoring a Vehicle to ‘Car Culture’ Status

What some call the “car culture” still exists today as many large, organized “cruises” are held in various metro areas during the summer, as well as a number of car shows in the country’s smaller towns. This year was special because my body and paint (B&P) man and I had just finished putting the finishing touches on my old 1st-series 1955 Chevrolet 3100 pickup, which I inherited from my dad in 1973.

Book Report: “Carroll Shelby, the Authorized Biography”

In the book “Carroll Shelby, the Authorized Biography,” author Rinsey Mills goes in-depth into Shelby’s historical racing and performance background.

Tech Tip: Importance of Valve Seat Concentricity in Engine Building

When it comes to gas engine remanufacturing, the subject of valve seat concentricity is a very serious one. Concentricity, as we are discussing here, is the relation between the centers of the valve guides and the centers of the valve seat surfaces.

Tech Talk: Career Building — Developing Engine Building Experiences in School

Though many high school automotive programs have been cut or reduced in recent years due to funding, community colleges and technical schools are seeing steady enrollment in their automotive programs.

Memory Lane: Marketing 101 — Seeing things from the Customer’s Perspective

What is important to you may not interest the customer at all.

Turbocharger Technology Continues to Improve

With the ability to increase fuel economy by up to 20% on gas vehicles and up to 40% on diesel vehicles, manufacturers have resorted to turbochargers to compensate for lowered engine displacement. Additionally, the improvements on turbocharging technology have increased the number of turbocharged vehicles on American roads. Some turbocharger manufacturers have even projected the number of turbocharged vehicles in the U.S. to quadruple in the next five years.

Returning Engine Power Through Fuel Injection Service

Over time, fuel injectors will become flow restricted from both the deposits that the gasoline leaves in them as it flows through the injectors and the carbon deposits that form on the head of the injectors, causing engine driveability issues

Ford Wins International Engine of the Year Awards 2012 in Dominant Style

The small but powerful 999cc, three-cylinder turbo unit wins Ford its first ever Engine of the Year Award

Tech Tip: Audi MIL Is On, Misfire DTCs P0300-P0312 Set

If an Audi customer complains that the engine has reduced performance without a significant loss of power or stalling, verify if Campaign 28F2/J1 has been performed (model years 2002-’07 only). Also determine if the vehicle is experiencing rough idle, the MIL is flashing or constantly illuminated, or one or more of the following DTCs are stored: DTC P0300 (Random/Multiple Cylinder Misfire Detected); DTC P0301-P0312 (Cyl. 1-12 Misfire Detected).

The Ins and Outs of Variable Valve Timing (VVT) Systems and Their Role in Vehicle Emissions

By the early 1990s, almost all import automotive manufacturers had a successful variable valve timing (VVT) system in production. These systems offered higher performance from smaller displacement engines at higher rpm. Do you know that VVT is playing a direct role in vehicle emissions and the way gases are burned in the combustion chamber?

Book Report: Tips for Ford Power Stroke Service and Rebuilds

The book covers the vast majority of Power Stroke diesel engines on the road, and gives you the full story on their design.

Tech Talk – Engine Innovations to Reach Government Fuel Standards

In recent years, the primary driving force behind engine innovation has been the never-ending quest for better fuel economy with little or no sacrifice in performance. Government regulations and rising fuel prices are forcing automakers to develop new technologies and powertrains that squeeze more power out of every drop of fuel while producing less pollution and greenhouse gas (carbon dioxide) emissions.
