Washington Way, President’s Agenda Daunting, But Is It Workable?

No matter what your political persuasion, no one can accuse President Bush of backing off or slowing down now that he has been re-elected. The debris from the inaugural parade and the many inaugural balls had barely been swept away before the administration began pushing its second term agenda. Many of these programs, such as

Crankshafts:Stock and Performance

The crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The leverage effect of the force exerted on the crank journals twists the shaft and converts the up-and-down reciprocating motion of the pistons into rotational motion of

Secret to Success is No Secret, Says Incoming AERA Chairman

John DeBates doesn’t understand what all the fuss is about. "I’m just a guy with a machine shop," he suggests. "I’m no superhero."

Perhaps it’s because he’s just a naturally funny, engaging and friendly personality. Perhaps

PERA’s Core Corner: Learn To Read The Bumps On GM Gen III Heads

Back a couple of hundred years ago, some brilliant thinkers believed that the bumps on your head could be used to diagnose your health or predict personality traits.

The Latest in TIG Welding Techniques & Equipment

Like the swallows coming back to Capistrano, the monarch butterflies finding the same wintering site in Mexico generation after generation or the buzzards returning faithfully to Hinckley, OH, in my neck of the woods, I am back with an annual March update on TIG welding in general and welding aluminum cylinder heads and other engine

Has Hot Honing Cooled Off?

No matter how perfectly straight and round it may be when it is machined, a cylinder bore will change shape when cylinder heads are installed and when the engine reaches normal operating temperatures.

Making Horsepower and Horse Sense From Your Dyno

A dyno can give an engine builder an enormous wealth of information and even separate the truth from lies. It’s one thing for a builder to have an idea of what the engine he or she is building is capable of and quite another to know exactly what’s been created. That’s because a dyno, more

Surfacing Equipment Options

On older cast iron engines with conventional soft-faced head gaskets, as long as the surface finish on the cylinder head and block deck is roughly 60 to 100 microinches Ra (roughness average), the head gasket should cold seal and remain leak-free for the life of the engine. But on late model bimetal (aluminum head/cast iron

Washington Way: Battle Over Heavy Duty OBD Repair Info Continues

In early 2003, the California Air Resources Board (CARB) decided to extend to heavy-duty vehicles the on-board-diagnostics information access rules then applicable only to automobiles and light duty vehicles. These access rules specify the information which the vehicle manufacturers have to make accessible from within the OBD system on their vehicles and from outside the
