Just Imports
So, you aren’t willing to work on import engines? To you they just seem too complicated and overwhelming? So you end up making the statement that you don’t do foreign vehicle repairs – or more specifically, import engine repairs. What happens when you get an offer to do a Mazda B2300 motor or work on
Dirt Track Dollars In the Shop and On the Track With Malcuit Racing Engines
It’s sometimes said that racers have motor oil or high octane racing fuel in their blood. Fearless drivers are accused of having ice-water running through their veins. For Strasburg, OH’s Brad Malcuit, the most likely ingredient pumping through his bloodstream is dirt, a fact he’ll happily attribute to family heritage. Malcuit is owner of Malcuit’s
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
Rebuilding The Ford 3.8L Engine
They needed an economy engine that would fit in their new cars, and they needed it fast. They had a couple of old inline sixes and a small German V6, but none of them were designed for fuel economy or the coming emissions standards, and the 250 cid engine was so tall that it wouldn’t
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
Little Engines, Big Money
For the rebuilding facility familiar with typical automotive or heavy-duty engines, the small displacement, four-cycle, air-cooled engine may seem insignificant. After all, these one-cylinder motors, which may produce just 5 hp, are found in lawn mowers, rototillers and kiddy go karts, for cryin’ out loud! Although the small four-cycle engines from Briggs & Stratton, Tecumseh,
Torque-to-Angle/Yield Threaded Fasteners
All the original equipment manufacturers (OEMs) have fastener labs with lots of sophisticated equipment and well-educated people working on fastening issues. They even have their own professional association – The Bolting Technology Council – which holds meetings and seminars about fasteners. I’m not a fastener engineer, and I’m not going to make you into one.

Engine Cylinder Bore Surface Finishes
What’s the best type of cylinder bore finish for today’s engines? Most would say it’s a finish that allows the rings to seat quickly and completely so the engine doesn’t use oil. For many applications, that may mean a plateau finish. The surface finish must also meet the piston ring manufacturer’s specifications and have the
Rebuilding the GM / Chevy 2.2L Engine
Unfortunately, this four cylinder, pushrod motor didn’t have nearly enough horsepower, so Buick, Oldsmobile and Pontiac all opted for the 1.8L SOHC Opel engine from Brazil for most of their “J” cars, and Chevy promptly made its new engine into a 2.0L/121 cid that delivered more power in 1983. The 2.0L was upgraded in 1987
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 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
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
Rebuilding the Chevrolet LT1 Engine
Although it shared many common dimensions, looked much the same and even had a few common parts, it was totally redesigned to provide more power with lower emissions and better fuel economy. Compared to the 1991 Chevy 350 L98 with TPI, the LT1 made 20% more horsepower, got better fuel mileage, and had a
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
Rebuilding The GM Quad 4
The Quad 4 had four valves per cylinder, tuned intake and exhaust manifolds, no distributor, no plug wires, lightweight rods and pistons to reduce shaking forces, and a crank with eight counterweights that was designed to reduce noise, vibration and harshness (NVH) and bearing wear. It didn’t have an A.I.R. pump or an EGR system,
Toyota 20R Engine
Toyota has built numerous four cylinder engine families over the years, but one that has been in use for quite a long time is the R-series. The R-series has been the main motor used in almost all Toyota pick-up trucks, as well as the rear-wheel-drive (RWD) Celica and Coronas. The 20R was introduced in 1975
Rebuilding the Buick 3300
The Buick 3300 was introduced in 1989 as areplacement for the 3.0L that had been around since 1982. It hadthe updated block with on-center bores, just like the revisedversion of the 3800 that came out the year before, along withseveral other changes and improvements. This engine was installed in many of the "A"bodied cars including
Machine Shop Market Profile
Interviews conducted with parts and equipmentsuppliers, as well as machine shop owners and custom engine rebuilders,generally point to market demand which has remained flat whenengine production numbers are compared to year earlier figures.Recent survey results of machine shops concerning production year1997 confirm these assumptions. Automotive Rebuilder magazine conducted a surveyof the machine shop membership of
Valve Stem Seals
Valve stem seals play a critical role in controlling valve lubrication as well as oil consumption. If the seals do not fit properly or are not installed correctly, the guides may be either starved for lubrication or flooded with oil. Either way, the engine is going to have problems – and you’re going to have
