The Mid-range Diesel Engine Market
The diesel engine market is a very complex one, but it can be broken down into three basic categories: light-, medium- and heavy-duty. These categories could then be broken down further into on-highway, off-highway and agricultural. In 2004 roughly 1.5 million new diesel engines were produced in North America, a whopping 79.6 percent of which

Engine Kit Opportunities
In nearly all aspects of today’s competitive consumer market, the customer is king, brand means everything, and warranties on parts and services are a given, right? Great news for the value-minded shopper, but what about the supplier? In the automotive industry, of course, OEMs have been offering unprecedented warranties and financing terms for the past
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
Not So Stock: NASCAR Motors and Their Street Counterparts
The engines in NASCAR’s newly introduced Strictly Stock class of stock car racing in 1949 were literally stock, right off the dealer’s showroom floor. Today, they’re anything but. So what happened? Evolution. Like any sport or industry, evolution has moved NASCAR racing to where it is today, a multi-million dollar business. The engines, called ‘motors’
Different engine-to-transmission dowels on Chrysler SOHC V6 engines?
Are there different engine-to-transmission dowels on Chrysler SOHC V6 engines? The AERA Technical Committee offers the following information regarding engine-to-transmission dowels on 1998 and 1999 Chrysler 3.2L and 3.5L SOHC V6 engines. A change was made in March of 1998 to the engine-to-transmission locating dowel length and block counter bore. The new dowel (p/n 06505643AA)
Engine Balancing
In the dark ages of the automotive industry, engine balancing was considered an art practiced exclusively by performance engine builders. Only those wizards of speed (it was widely believed) could understand the forces that caused drivetrain vibration – and more importantly, those that stopped it. Those few who could balance an engine were looked upon
New Clean Diesel Technology
With gasoline prices in the U.S. bouncing around the two dollars per gallon mark, record high oil prices and growing uncertainty over the price and availability of future oil supplies, any new technology that can give consumers more bang for their buck should be welcomed. Domestic vehicle manufacturers have virtually abandoned further development of electric
Front engine oil leak on 1999-2003 Suzuki 2.5 & 2.7L engines
Engine Builders: The AERA Technical Committee offers the following information regarding a front engine oil leak on 1999-2003 Suzuki 2.5 & 2.7L engines. If oil is observed leaking from the left front of the engine resealing the timing cover may resolve those types of customer complaints. To do so, two types of sealers are recommended
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
Researching the Rebuilding Market for Multi-Valve Cylinder Heads
Cylinder head work has provided a good income for many of our readers over the years. All engines eventually need a valve job and guide work if they accumulate enough miles. Head work may also be needed if an engine overheats and blows a head gasket, if the head develops a crack, or an OHC
OBD II Shop
Having come from the era of the muscle car, it is extremely interesting to me to get out and look at the new vehicles, feel the performance and see the technology that makes the tailpipe emissions half of what they were in 1996. This technology is made possible by faster power train control modules that
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
Rebuilding The Chrysler 2.7L
It was rated at 200 HP and it was originally used as the base motor in the Intrepid and Concorde, but it’s been the optional engine in the Stratus and Sebring since 2001 and it will be the standard engine in Chrysler’s new 300 sedan that’s coming out later this year. So, while there are
Core Corner
Whenever I see a new subdivision being built further out into the rural areas of larger cities, I think about the new owners, many of whom will be young married couples moving out of apartments or condos and finally getting to that place where they are ready to start a family. Once that baby booming
Pushrods – Key To Performance
Pushrods are the weakest link in the upper valvetrain. Pushrods transfer and redirect the upward motion of the lifters, which goes in one direction, to the rocker arms which move in another direction. Consequently, they are subjected to bending forces as the load and engine speed increases. For stock engines, mild steel stock pushrods are
In Search Of New Markets, Mike Jeffries
Looking for new markets is one of the toughest things we do, so every time the phone rings we listen for an opportunity. Most of what we find is suspect, but over the past 12 months we have rebuilt a number of compact diesels and sold a number of rebuild kits. As a result we
What’s Wrong With Our Industry
What’s wrong with the engine building industry today? It’s a simple question that has no simple answer. Like many other if not every industry facing difficult times, the factors impacting this market are varied, complex and frustratingly hard to pin down. Are the woes of the industry the fault of customers or suppliers?
