Rebuilding the Chevrolet LT1 Engine

Compared to the 1991 Chevy 350 L98 with TPI, the LT1 made 20 percent more horsepower, got better fuel mileage, and had a much broader torque band with 90 percent of its peak torque available from just over 1,000 rpm all the way up to nearly 6,000 rpm. GM Powertrain accomplished all of this by

Rebuilding the New Chevy 262

This enabled GM to shorten the development process dramatically because it was able to adapt a proven design. But it also allowed it to share a lot of the existing tooling from the V8 production lines so the engines could be on the road sooner. The original 200 V6 that came out in 1978 was

Updating GM’s Quad 4 Engine

The Olds Quad 4 was the first production, four-valve, DOHC four cylinder engine built by General Motors. When it was introduced in 1987, it was heralded as a revolutionary new design that was expected to be as historically significant as the original Olds Rocket V8 was in 1949. The Quad 4 had four valves per

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 Today’s Cylinder Heads

Everybody wants to get ahead in the cylinder head rebuilding business

Core Cleaning: A Closer Look at the Issues and Regulations That Are Driving Today’s Market

On the list of hot button issues in the engine rebuilding business, the disposal of waste usually takes a backseat to supplier consolidations, market share position, profitability and other topics. On the other hand, the amount of time, effort and money that rebuilders spend, all of it non-productive, in meeting regulatory requirements can be significant.

Chrysler Shop Solutions

Chrysler/ Mitsubishi 2.6L/3.0L Some of the late 2.6L engines and all of the 3.0L Mitsubishi engines have a very small "auto-lash-adjuster" installed in the tip of the rocker. All too often, air gets trapped in the lower chamber of the lifter and prevents oil from filling the lifter. When this happens, the lifter holds the

Newer OBD-II Blocks Require Much More Attention To Proper Honing Procedures

Smoother finishes, tighter tolerances mean stricter standards and processes Want to guarantee a comeback? When you are honing the cylinders on a late model engine, use the hardest cutting stones you have. Run the hone as fast as you can so you finish the job quickly. Working hard and fast generates a lot of heat

TIG Welding Aluminum

The last thing you want to find when rebuilding a cylinder head is a crack. Yet cracks are common in many of today

Understanding Today’s Machine Coolants

Many types of grinding and honing operations require the use of a "process fluid" for cooling and lubrication. Remanufacturing procedures such as crankshaft grinding and surface grinding generate a tremendous amount of heat and require a fluid primarily for cooling. Heat control is absolutely essential for a good finish and accurate tolerances. Use of a

ECU Affect on Rebuilt Engines: Knowing the Basics Can Prevent Costly Comebacks

When a customer purchases a rebuilt engine they expect to get many miles from their investment. But there are many things which must be done right to assure that this happens. One area that is increasingly important in this regard pertains to the engine
