Calico Coatings Moving to New, Larger Facility in North Carolina
“We have been planning this move for more than a year now,” said Calico Coatings president, Tracy Trotter. “We’re having our best year since we’ve been in business and it was crucial that we completed this expansion in order to keep up with current demand and accommodate future growth opportunities.” Headquartered in the Denver area,
What You Can
To put things in perspective, .0015? isequal to 32 micron. These particles are small enough to get into that space justahead of the cam lobe and lifter contact area. Small particles can get in betweenthe roller and the axle on a roller lifter. Even worse, hard particles canscore the bore of the plunger in hydraulic
Performance Oil Systems
For the engine to survive, the oiling system must be capable of supplying an adequate volume of oil under a wide range of operating conditions. The oiling system must also maintain adequate pressure to keep the oil flowing to all of the places where it is needed. Critical among them are the crankshaft and camshaft
New Products for Modern V8 Engines
The numbers aren’t there yet, but engine builders and suppliers are taking notice of the new V8s. What has taken so long? For one, the new engines are more expensive and more complex. Some shops do not have the capability or expertise to work on them just yet, but more and more shops do. One
Engine Bearings and Crankshafts: Best Friends Forever (BFFs)
Bearings appear to be such simple engine components. On the surface, they’re just half-circles of metal whose only purpose is to reduce friction between and support moving parts. The engine bearing has to establish and maintain a film of oil between moving and stationary parts to prevent wear to expensive engine components. They look like
Making Dollars and Sense Cleaning Blocks, Heads
Unless you’re starting with all new parts, cleaning is as important to your engine build as disassembly, inspection, machining and reassembly. Without taking the cylinder heads and engine blocks down to bare metal, you can’t properly inspect the castings for cracks, wear and other defects. For something so important, proper cleaning technique is often misunderstood, overlooked
Cylinder Bores-Machining To Sleeving
The function of a cylinder bore is fairly simple yet quite demanding. The bore is nothing more than a cylindrical void which contains the engine’s air/fuel mixture as it undergoes compression and combustion. The walls of the cylinder have to be strong enough and rigid enough to withstand high combustion pressures and temperatures
PCV System: Sometimes Things Just Have To
I am certain that each and every one of you have, at some time in your life, experienced the horrific event of having the “wind” knocked out of you. If you can remember back to the first time it ever happened, before you knew that you would in fact breathe again, it was like you
Smooth Moves: Today’s Surfaces Often Demand Different Finishes
When multi-layer steel (MLS) head gaskets became commonplace a number of years ago, there was a lot of concern that aftermarket surfacing procedures might not be able to reproduce the mirror-like finish that the vehicle manufacturers said was absolutely necessary to seal MLS head gaskets. The challenge was to duplicate the factory finish using out-dated
Understanding Today
Metallurgy is one of the oldest sciences in the world – it’s a history that can be traced back to the beginnings of civilization. It’s hard to believe that in the thousands of years since the discovery of gold and silver there have only been 84 new metals discovered. In fact, when the automobile was
Nailing Down The Buick Nailhead
Likethe Small Block Chevy, the Rocket 88 Olds, the Ford Flathead and the ChryslerHemi, the Buick Nailhead engine is one of those that has the immortal smell ofhistory all over it. Yet,unlike its more familiar brothers, cousins and even competitors, the Nailheadhas an aura of mystery about it as well. TheNailhead had a
Rally and Off-Road Racing Engines
Early automobile races were held on horse tracks or dirt covered roads, but then came pavement and over the decades, many racers forgot about dirt. Today, racers who like to kick dirt will tell you there’s a whole other world of racing in the off-road market. Cleanliness may be next to godliness, but getting dirty
Cylinder Sleeves and Liners
Iron sleeves provide a wear-resistant surface for the piston rings, and they don’t have to be very thick because they are supported by the surrounding block. Cast iron blocks, by comparison, don’t need cylinder sleeves because the iron is hard enough to resist ring wear. If a cylinder is cracked, damaged or worn to the
High Tech Cleaning Options
Yet while machining tolerances and performance expectations have changed dramatically over the past few decades, when it comes to getting parts clean, many of those high-tech shops struggle with the same technology they used 30 years ago. The simple fact is, times have changed for parts cleaning, and so have the methods. Engine builders have
Cleaning: Different Methods for Different Needs
Back in the late 1800s, the director of the U.S. Patent Office was said to remark “Everything that can be invented has been invented.” Charles Duell, U.S. Patent Commissioner in 1899 reportedly told the President of the United States that there was no more innovation and, therefore, no more need for the patent office. Except
Understanding Dyno Numbers’ Place in Your Business
It is very difficult to cover all of what you need to know about dyno testing in an article of this length, but perhaps I can take a swing at nailing some of the critical information down. Dyno testing is an important part of engine development programs and can provide an improvement in quality control
Engine Blocks & Cylinder Sleeves
In our February 2009 issue, Technical Editor Larry Carley provided a comprehensive overview of the changes in engine blocks over the years. Thanks in part to natural attrition (after all, many of the most popular engines were actually designed and built more than 50 years ago) and the high price for scrap metal in the
Putting the Pressure On High Power Cleaning Systems
Despite these automated times in which we live today, many shops still use manual cleaning systems to hand-clean each engine component piece by piece. This may seem slow and tedious to some, but for others it’s necessary quality control in order to remove all of the hidden particles that can cause damage to an engine
Cleaning Rules
One of the least pleasant parts of any engine builder’s day is the cleaning process. Removing the oil, carbon and general gunk from blocks, cylinder heads and assorted parts before your inspection, machining and rebuilding process can even begin may seem as painful as a trip to the dentist’s chair. But if you think that
Engine Sealing Technology
Since the days of sealing engines with asbestos, cork, rope and paper are, for the most part, ancient history, new-age materials and designs have elevated the critical role gaskets and seals play in the longevity of an engine. Finding the optimum sealing material and design remain a challenge many gasket manufacturers face as engines are
