Timing Chains, Sprockets and Gears
Look back at the events in your life an examine how timing has played a part in the outcome. When you showed up at party and met the girl who would eventually become your wife? When you stayed late at work and missed the 18-car pile up on the interstate? Even without realizing it, your
Rebuilding the Chrysler 3.3L / 3.8L Engine
Before we run through the changes, though, here’s a quick overview of the 3.3L and 3.8L engines: (download the illustrated pdf here) • They’re conventional 60 degree V6 motors with iron blocks and aluminum heads, including some castings that are shared by both engines and some that aren’t. • The differences between
AERA to hold Don Gross Regional Conference
AERA is doing its part to make gaining knowledge and networking opportunities easier by holding a series of regional conferences instead of a larger, national one. Along with the outlined technical programs, AERA is inviting leading manufacturers of engine building/rebuilding tools, supplies, services, parts and machinery to attend this conference. These suppliers will have table-top
Valve and Guide Material, Selection Update
Today’s engines are being designed with more valves per cylinder with smaller valves to reduce valve train weight and increase intake volume. Cylinder heads typically require valve guide and seat work to restore compression and oil control if you are rebuilding the heads. For the valve to seat properly and to gain the most power
Chevy LT1 Engine and Reverse-Flow Technology
The Chevrolet LT1 5.7L V8 engine that was produced from 1992 to 1997 has some significant differences compared to the previous small block Chevy it replaced, and the third generation LS1 small block that later replaced it. The most obvious difference that distinguishes the LT1 from these other engines is the front-mounted Opti-Spark ignition system.

Diesel Cylinder Head Rebuilding
If you have ever tried to start most diesel engines in cold weather, you know that you have to have an engine heater, or you have to have a starting aid like starting fluid. These engines most commonly did not have a computer, and the fuel pressure would be in the range of around 3,000
Rebuilding the 3.8L Buick Engine
The Buick 3.8L has evolved from its humble beginnings as a cheap, easy to build, economy motor in 1962 into one of the best pushrod motors in the world. It started in life as a Buick V8 that had two cylinders “missing,” because that allowed GM to machine it on the same line as their
Tech Notes
Engine Builders: Maintaining oil drain intervals to those established by OEMs is always recommended because they know how each of their vehicles’ engines performs in the field. Always consult the owner’s manual for oil specification and drain interval. Premium quality motor oil will maintain its effectiveness over the life of the drain without a significant
Rebuilding The Chrysler 2.4L
Chrysler replaced its old SOHC four cylinders with an all-new family of SOHC and DOHC engines in 1995. There were 2.0L SOHC and DOHC versions, along with a 2.4L DOHC that was installed in the FWD cars and minivans. Add seven different head castings that came with and without EGR and A.I.R. and throw in
Shop Line
We’ve had customer complaints about recurring MILs (malfunctioning indicator light) on some Chrysler 3.2 and 3.5L engines. Any idea what’s going on? The AERA Technical Committee offers the following information regarding a revised valve spring for 1998-2004 Chrysler 3.2 and 3.5L VIN J, G, K, M & V engines. This revision is the result of
Performance Notes: Cashing In On Power Adders: Blowers, Turbos, Nitrous
The demand for high performance vehicles has never been stronger. A good indicator is that automakers are turning out more powerful models with each successive new car introduction. Remember when 500 horsepower was a pretty good number for a race motor? Today you can purchase a number of vehicles that eclipse 500hp, from a Z06
Crack Detection
Take a look in the mirror. Smiling back at you, you’ll notice that row of pearly whites. They probably look pretty good. Maybe a bit stained from coffee or smoking, but overall, they seem to be pretty solid, right? If you’re like many people, the fear sets in as soon as you sit down in
Line Boring Equipment: A Boring Subject?
But as the British philosopher Bertrand Russell noted, "Change is one thing; progress is another." While some might say the basic techniques for line boring main and cam bearing bores in engine blocks hasn’t changed much in 30 years others say that isn’t such a bad thing. A horizontal boring bar with cutters mounted on
Cylinder Head Crack Repairs
It seems as if many cylinder heads are doomed to crack from the very start because of their lightweight construction and design. Aluminum overhead cam (OHC) heads, in particular, are often found to be warped as well as cracked. But so too are many pushrod cast iron heads. One of the causes of cracking in
Connecting Rod Reconditioning: More to it than you might think
The connecting rod plays a vital role in the engine. But a connecting rod is under tremendous stress, with the weight of the piston sitting on top, changing direction thousands of times per minute. This continuous stopping and changing of direction combined with the weight of the piston and speed of the engine hammer on
Gen III GM Small Block Engine, LS1 Motor for Cars, Trucks
The first generation small block was revised to create the second generation LT1/LT4 that was used for some applications from ’92 to ’97, but the results didn’t satisfy the people at GM Powertrain, so they started all over in ’91 and designed a brand new small block. It’s officially called the “Gen III” motor, but

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
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
