Got a Minute? – Educating the customer
Time is an interesting construct. If you look at its history, you begin to realize that there is no real reason for a minute to have 60 seconds, an hour to have 60 minutes or a day to have 24 hours, or for us to divide those 24 hours into 12 hours of daylight and
Timing Chains & Gears
As a rule, most pushrod engines use a timing chain to drive the camshaft, though some older four and six cylinder engines use a gear set. A short chain or gear set works well in this kind of application because the camshaft is located in the block just above the crankshaft. In overhead cam (OHC)
The Tool Salesman Doesn
Our tool man, or perhaps I should say tool person, doesn’t stop at our shop any longer. First one week, then another went by without seeing the tool person pull in. I thought perhaps our tool person had gone on vacation without telling us, or even worse had gotten sick. After a few weeks, I
How Wegner Automotive Reverse Engineers Cylinder Head Porting
Casey Wegner, head of the CNC department at Wegner Automotive, Markesan, WI, can still picture this scene from his childhood: His father Carl meticulously hand porting a cylinder head, which took several days to finish an entire set of ports for an eight-cylinder engine. Fast-forward 30 years: Casey Wegner has become an expert head porter,
Coretalk: Key Industry Speakers Slated For PERA’s Chicago Convention

Engintel: Learning Not To Feel Like A Sucker
I recently encountered an interesting situation that initially had me wondering if all hope for installation and general repair technicians was gone; and that perhaps some of the bum rap that they seem to get may be justified. Instead, I got a healthy meal of "crow" wrapped in a tortilla of humility. Imagine getting a
Resurfacing Cylinder Heads & Blocks? Mistakes to Avoid
Cylinder heads and blocks may need to be resurfaced to restore flatness or to improve the surface finish, or milled to change the deck height for a variety of reasons. The deck surface on the head or block may need to be resurfaced if the surface isn’t smooth or flat. A head may need to
Honing Stones & Equipment
The finish on the cylinder walls is critical for proper piston ringlubrication and sealing. The bore geometry is also important, and mustbe round, cylindrical and straight for optimum sealing and minimumblowby. The equipment used to hone cylinders has changed in recent years as thedemand for better surface finishes, faster cycle times and lowerproduction costs have
Coretalk: Engine Builders Asked To Show ERC Support on Business Web Sites
The Web site contains a variety of tips, articles and other tools aimed at consumers seeking information about engine repowering. An update of the site’s engine installer and remanufacturer/rebuilder shop finder service is still under construction. “We need to get more engine builders and installers to get involved with ERC so that customers can easily
From Block Work to Manufacturing – CNC Machines Wear Many Hats
From a shop owner’s perspective, a good employee is one who’s never late, is extremely productive and never asks for a raise. Enter the perfect employee: the multi-purpose computer numeric controlled (CNC) machine center can do the work of several employees and never complain about it. There is no doubt that today’s machine shops must
Stroker Engine Kits
For more than 50 years the old saying “There’s no substitute for cubic inches” has been the credo of nearly every racer and hot rodder. Whoever created this unwritten universal law could never have imagined to what extremes today’s speed enthusiasts would take it. Now, unless you have a 420cid-plus small-block or a 550cid-plus big-block
Dynamometers and Dyno Operating Systems
The data collected while an engine is running on a dyno can be analyzed to maximize the power gains from various modifications (changes in the fuel mixture, ignition timing, valve timing, compression, the induction system, exhaust system, etc.). Performance engine builders use dynos to measure horsepower and torque so they can optimize engine performance. By
Building Hot Rods & Muscle Car Engines
Sometimes the best opportunities are cleverly hidden in plain view. As one example, when Chris Lafferty of Lafferty Engine Creations was asked why he opted to expand beyond race engines into the hot rod and muscle car arenas, he snorted, “Just look outside.” His North Carolina facility sits squarely in the middle of both NASCAR
Over the Peaks and Into the Valleys – Hones, Diamonds and Bores
“Your mission, should you choose to accept it, is to find the recipe for perfect bores…your instructions are to produce bores that are perfectly straight and round. This message will self-destruct after five minutes. Good luck.” Although it’s not “Mission: Impossible,” good bore geometry is critical in order to achieve proper ring sealing. Bore distortion
Coretalk: MAHLE Group to Acquire Dana Corp’s Engine Hard Parts Business Units

In connection with the transaction, the parties will enter into ancillary agreements including an agreement granting MAHLE exclusive distribution rights to Dana’s retained Victor Reinz branded products in the independent aftermarket in the
Tech Notes
Engine Builders: What is viscosity breakdown? All of us in this business understand an SAE 5W-20 oil is thinner in viscosity than an SAE 10W-30 and that the “W” stands for winter, but that’s probably about where it stops even though there is more to the story. Motor oils thin in viscosity as they warm
Engine Parts ETs Drop From Inspiration to Installation
It’s a simple process for those down in the trenches. An engine builder will make a phone call or click on a computer and within days, the latest parts show up at his shop, ready to be installed. But the traditional Stork method of delivery notwithstanding, exactly where do new engine parts actually come from?
Machine Maintenance: There’s Nothing Boring About Boring Bar Maintenance
You know the feeling: the machine you want, you can’t afford, and the machine you can afford you already have. Don’t you wish, just once, you could call up the sales representative and say “My turn, send me one of those new ‘XYZ’ machines?” You know the kind, the new state-of-the-art machining center that can
Coretalk: New Brochure, Poster And Web Site Promote The Benefits of ‘Repowering’
Limited quantities of the “Serious Engine Trouble?” brochure are available to industry professionals by contacting ERC at [email protected]. “The new brochure encourages motorists to talk with their automotive technician and consider all of their options when faced with major engine trouble,” said ERC Chairman Tom Schrader. “Often times, choosing to repower the current engine is
Fast Lane: Boosting Your Business With A Web Presence – Part II
In part one of this series (“A Web Site Can Add To Your Business Bottom Line,” August 2006 Engine Builder, page 38) we talked about the need for every business to have a Web site, regardless of what type of business you are in. Sadly, in the recent Machine Shop Market Profile in this very
