Mitch’s World: Personal Axe Grinding…Shows Ignorance, Especially When Done in “First Person”
I am a “first person” writer. I write about things that I’ve either experienced personally, or that have profoundly affected me in some powerful or compelling way. Almost without exception, these “things” occur either at the shop or have at least something to do with what goes on there. They are things that, in some
Directions: The Evolving Story of Electric Vehicles
The latest chapter in the evolving story of electric vehicles (EV) begins with a tale of two very different models. One is downright sexy, with alluring aerodynamic lines and head-turning, sporty styling. The other is, well, downright cute — a spunky little thing that looks a bit like a colorful helmet on wheels. At first
Diagnostic Dilemmas
It’s Mechanical, Stupid! Just about every student of politics remembers President Bill Clinton’s famous campaign slogan, “It’s the economy, stupid!” Allow me to paraphrase by saying, “It’s mechanical, stupid!” Yes, that’s right, mechanical failures can cause diagnostic trouble codes and, all too often, we tread the Primrose Path because we become lost in a maze
Chevy AVEO Timing Belt Service
As a rule, General Motors uses timing chains rather than timing belts on most of its engines. Timing chains are long-lived and reliable, and do not have a recommended replacement interval. Not so with timing belts. One GM engine that does use a rubber timing belt is the 1.6L E-TECH II engine in the 2004

Tech Tip: Catalytic Converters Play an Important Role in the Emissions-Compliant Engine
The design and function of catalytic converters has changed dramatically since their introduction in 1975. The first "two-way" catalytic converters were oxidizing-only designs that combined hydrocarbon (HC) and carbon monoxide (CO) with oxygen to form water vapor (H2O) and carbon dioxide (CO2). Oxidizing converters were originally manufactured in pellet bed or monolithic "honeycomb" styles. Currently, the monolithic style has proven to be the most durable.
Tech Tip: Can You Explain the Differences? Torque vs. Horsepower
Everyone who works with cars or trucks is familiar with the terms torque and horsepower. But do you understand the difference between the two and can you explain it to a customer? It’s important to have a sound understanding of both, and the ability to comprehend what defines each measurement of output.

Engine Tech Tip: Measuring Blowby
You’ve built an engine exactly the same as the last engine, but the power seems to be down 10 to 20 horsepower on the dyno. Could it be excessive blowby because of a ring sealing problem? One way to find out is to measure crankcase blowby.
