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

Crank And Cam Polishing: Are You Smooth Enough?
Manufacturers are designing today’s engines with tighter tolerances and less room for error. They make more power, live longer, produce less noise, vibration and friction, burn less fuel and produce lower emissions. So in light of all this, it is more important than ever for engine builders to be as perfect, or near perfect, as
What’s Hot In Performance – Cams, Lifters & Rockers
The camshaft is really the heart of every performance engine because the cam defines the engine’s breathing potential, its torque curve and peak horsepower. The camshaft controls when the valves open, how quickly they open, how far they open (with some help from the rocker arms), how long the valves are held open, and when
Jeeps: 4.0L Cylinder Heads
The 4.0L came on the scene in 1987 and is still being used, however 2005 may be the end of the journey in domestic production. It’ll be a bittersweet farewell: most who have it love it. This is an old school inline six with lots of torque and there are still many of them out
Ford Timing Chains and Belts
So if a customer is driving a vehicle that is more than 5 or 6 years old, he may be driving on borrowed time if the timing belt has not been replaced. The risk of belt failure goes up sharply once a belt surpasses its recommended replacement interval, which for most Ford applications (except the
Big-Inch Cadillac’s
While some engines are relatively rare in machine shops, the big Cadillacs have remained a consistent source of income. These engines are Cadillac’s last big hurrah at traditional big-cube, flagship GM engines. Surprisingly, they are also a scaled-down version of a V-12 engine that made it through early production and road-testing before being scrapped as
Guide and Seat Equipment
Cylinder head work has been and should continue to be a profit center for engine builders. Heads almost always require guide and seat work to restore compression and oil control. This includes drilling, reaming and replacing valve guides, removing worn, loose or damaged valve seats, cutting new seat counterbores, and machining valve seats. For performance
Bad For The Auto Industry, Good For Rebuilding
The headline in the Dallas Morning News caught my eye: “New Car Customers With Negative Equity Are Growing Problem For Auto Industry.” The words “negative” and “problem” are well-recognized around this segment of the “auto industry” so, of course, I read on to see how this story would impact the Engine Builder reader. To my
Building Drag Racing Cylinder Heads
One thing every drag racer wants is to go faster – even bracket racers. There are lots of ways to shave tenths of seconds and even whole seconds off an elapsed time. It all comes down to how much money the racer is willing to spend in his quest for speed. One way to go
Cylinder Bore Refinishing with Honing Tools
By ring friendly, we mean a finish that provides good support for the rings, retains oil and does not require a lengthy break-in period. For most engines today, a ring-friendly finish means a plateau finish. A plateau bore finish is what all types of rings eventually produce when they are fully seated, so the closer
Spray Washer Maintenance Tips
In the 2003 Engine Builder Machine Shop Market Profile (Engine Builder, June 2003), shop owners said cleaning/disassembly were their most time consuming parts of the rebuild process. Survey respondents said that 13.8 percent of an average rebuild is spent in this area, down 2 percent from the previous year. In the same survey, 80 percent
The New Sport Compact Market
The most popular nameplates are imports such as Honda, Acura and Mitsubishi, but coming on fast are Nissan, Toyota, Mazda, Subaru and Volkswagen – plus domestic models such as Ford Focus, Dodge Neon and even Chevy Cavalier. Nobody is abandoning the small block Chevy or any of the other V8s that have traditionally been the
Back to Basics: Preventing Piston Problems
Burned pistons. Scuffed pistons. Cracked pistons. These are problems no customer wants to experience in an engine you’ve built. Warranty claims can kill your business, so here are some tips on how to prevent these and other common piston problems. First and foremost, if you’re custom building an engine that has already suffered some kind
Cleaning – Do You Know Where Your Dollars Are?
Cleaning parts in the machine shop doesn’tcome cheaply. According to Automotive Rebuilder’s Machine ShopMarket Profile about 15.2% of engine machining and rebuildingproduction work involves disassembly and cleaning. According torebuilders that we surveyed, disassembly and cleaning accountedfor the highest percentage of total rebuilding production timein the shop. So there can be significant benefits to reducingcleaning costs
Building Horsepower Through Dyno Testing
Pick up a copy of any racing-oriented automotive publication andas you thumb through its pages you’ll notice a smorgasbord ofads from engine builders. Most of them will have an assortmentof horsepower figures large enough to rival the national debt. Of course, all the numbers are suspect because, in most cases,they were obtained on the advertisers’
Valvetrains: Better Materials & Design
Pushrods would seem to be an endangered species these days, atleast as far as most new engine designs are concerned. The onlybrand new engines built in recent years with a pushrod valvetrainhave been Chrysler’s 8.0L V10 for the Viper and Dodge Ram, andGeneral Motors new "LS1" 5.7L small block V8. All therest have either been
Niche Market Opportunities
In today’s highly competitive market, it makes sense to constantlybe on the lookout for new opportunities. Information on the marketsdescribed in this article may provide some new business prospectsfor those shops not already involved with them. However, rebuildersshould constantly be prospecting for other niche markets for theirexisting products or services. There are potentially many products
Blasting Technology: This Cost-Effective Cleaning Procedure Has Improved
When it comes to parts cleaning by blasting,the idea of propelling abrasives at parts to clean them of rust,carbon, paint or other difficult contaminants is a simple one.But the technology involved with this cost-effective cleaningprocedure has improved, and rebuilders can take advantage of manyoptions to eliminate out-dated, labor-intensive cleaning practicesin the shop.

So it’s important to remember when deciding on a specific approach to cleaning to strive for cleaning effectiveness, while at the same time, staying in compliance with Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) regulations. In order for a machine shop to have a positive return on investment, cleaning systems and
