Tech Notes
Engine Builders: The AERA Technical Committee offers the following information regarding camshaft identification for 2001-2003 Hyundai 3.0 and 3.5L engines. Previously published service manual information has been called misleading, resulting in incorrect assembly. Each of these engines use four unique camshafts that look the same. Each camshaft for the 3.0L and 3.5L engine is etched
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
Tech Notes
Engine Builders: The AERA Technical Committee offers the following information regarding engine failure on 1998-2004 Chrysler 2.7L VIN R, U & V engines. There have been reports of premature engine failure on these engines, failures that may include tensioner failures, oil consumption and engine bearing failure. It has been suggested that many of these failures
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
Tractor Pulling: It’s Not Your Granddad’s John Deere Anymore
Tractor pulling has been with us for as long as there have been tractors. Farmers used to pull their horses, mules or oxen and, just as today, each bragged that he had the biggest and strongest. Today, at the top echelons of pulling, the technology is equal to anything else in motorsports. Although you won’t
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
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)
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
PERA’S Core Corner
Unless you maintain the correct Focus on the engine blocks being used for Ford 2.0L SOHC applications beginning in 1997 you could certainly end being Escort-ed down the wrong path and ending up in that awful position of a “do over.” In fact the block choices per application remind me of the “Mounds” and “Almond
Is there any updated information regarding cam timing on Ford 4.0L engines?
Some service manual information regarding camshaft timing for 1997-2003 Ford 4.0L VIN E engines is erroneous. Ford published the correct information in a service bulletin dated May 2001 as part of a cam chain guide campaign. Subsequent year manuals should have the updated information depending on their source. Basically, the left and right side camshafts
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
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

Engine Builders: The following information is for installers regarding timing belt installation procedures on 1994-2001 Acura B18 Series engines. Failure to follow these procedures could result in engine damage. Position the crankshaft and the camshaft pulleys as shown in Figure 1 before installing the timing belt. Set the crankshaft so that the No. 1 piston
Coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines
Engine Builders: The AERA Technical Committee offers the following information regarding coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines due to failure of the intake manifold gasket. GM has redesigned a new intake manifold gasket (p/n 89017279) to reduce the chance of failure. The material used in
Engine Crack Detection Technology
It doesn’t matter if you’re rebuilding a high mileage engine and reusing salvaged components or using brand new parts right out of the box – any highly stressed component or casting that has to withstand high loads, temperatures and/or pressures should always be inspected to make sure it is free from cracks or other defects
Ford 4.0L V6 Engine
The original 2.6L engine was replaced by the 2.8L, which was upgraded to the 2.9L and then finally bored and stroked to make it into the 4.0L that was used in the Rangers, Aerostars and Explorers starting in 1990. It was replaced by a SOHC engine from this same family at the end of model
Toyota 3SGTE Engine
First of all, one needs to realize that Toyota, like GM, Ford, etc., has engine “families”. However, rather than calling them names such as “big block” or “small block,” Toyota assigns them a letter code. The engine family code is the first letter (not the first numeral). The codes are as follows: A-series: 1.5L, 1.6L
Rebuilding Toyota 3.0L V6 Engine
In 1988 Toyota introduced its first V6. Most of the information that follows applies to the 3.0L version used in Toyota’s truck applications. The 3.4L is still fairly new to the aftermarket at this point. 3VZ-E – 3.0L SOHC V6 – ’88-’95 The 3VZ-E was also introduced for the 1988 model year on Toyota 4×4
Mopar Engine Platforms – 318, 360
Chrysler Corp. hasn’t built a rear wheel drive, V8-powered car (with the exception of the Viper) since the turn of the decade. And the cars that harbored V8s beneath their hoods during the late 1980s were about as appealing to performance enthusiasts as the front-wheel driven vehicles that replaced them. In spite of that fact,
