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
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
Cleaning With Jet Spray Washers: Replacing Solvent Cleaning Processes With Aqueous Cleaning.
As more environmental regulations phase outmany chlorinated solvents and ozone depleting chemicals, manyautomotive machine shops and engine rebuilding operations arereplacing their solvent cleaning processes with aqueous cleaning.Some argue that while replacement chemicals have been found, theirtotal safety and part cleaning applicability has not been researchedenough. According to many rebuilders and equipment makers, developmentsin aqueous cleaning
Small Engine Performance
Most businesses have the same problems and each must look for ways to remain competitive by reducing costs and exploring new markets for existing products or services. And so it is in engine building. There is always someone that is able to provide more features per dollar than you (or at least make someone believe
The Nitty Gritty On Small Parts Cleaning: Many Ways To Clean Small Engine Parts
Tom Nichols, CEO and president of AutomotiveMachine & Supply, Inc., Fort Worth, TX, said availabilityis most often the key to why his shop cleans and reuses smallparts. Nichols said each day his shop cleans and reuses many smallparts, including valve locks, shims, springs, retainers, rockerarm assemblies, cam bore caps, nuts, bolts, etc. "Becausewe only
Performance Marine Engines – Meeting Customer Expectations
Life is a series of compromises. Human relations almost alwaysinvolves compromises of some sort. You want Chinese for dinner,she wants Italian; something has to give. Even if you go yourseparate ways, it’s a compromise and a decision to not dine together. Believe it or not, it’s the same with machinery. Any exercisein design is a
1997 Shop Kinks
Machine shops and custom engine rebuilders are, and always havebeen, a resourceful group. Our industry was founded on the principalof bringing component parts from a condition of disrepair to onethat offers equivalent performance to that of a new part. Rebuilt engines offer cost savings and performance benefits thatcan not be found with any other products,

Ontario Reman isan authorized Chrysler engine rebuilder selling remanufacturedengines and small parts to Canadian Chrysler dealers. We thankthem! Chrysler introduced a whole new family of 60degree V6 engines beginning with the 3.3L OHV
Power Investments, Inc.: Building An Empire In The Rebuilding Industry
Mike Jarvis, 53, president of Power Investments,Inc., is quietly building an empire in the rebuilding industry.If you want proof, just take a look at his frequent flyer miles(he’s averaged about 2,500 business miles per week over the pastfour years), and the fact that company growth has averaged between12-18% per year, mostly through acquisitions, since 1983.
Blasting Technology: This Cost-Effective Cleaning Procedure Has Improved
When it comes to parts cleaning by blasting,the idea of propelling abrasives at parts to clean them of rust,carbon, paint or other difficult contaminants is a simple one.But the technology involved with this cost-effective cleaningprocedure has improved, and rebuilders can take advantage of manyoptions to eliminate out-dated, labor-intensive cleaning practicesin the shop. Scott Christiansen of
Engines Market: Total Engine Production Generated By Manufacturers In The U.S. And Canada Increased in 1996
Annual production of remanufactured enginesclimbed from 1.32 million in 1995 to 1.57 million during 1996– an increase of about 19.4%. Engine production figures are based on a universe of 120 U.S.and Canadian rebuilders that rebuilt an average of 13,113 short,long and complete engines each last year. Survey results werecompiled from a detailed questionnaire mailed to
Ensuring Bearing Life: Crankshaft Bearings Are Always Replaced When Rebuilding An Engine
Crankshaft bearings are always replaced when rebuilding an engine because they’re a wear component. Heat, pressure, chemical attack, abrasion and loss of lubrication can all contribute to deterioration of the bearings. Consequently, when an engine is rebuilt new bearings are always installed. “Reading” the old bearings can reveal a great deal about conditions that may
