Valve Guide Reconditioning
A valve loses about 15 to 30 percent of its heat through the stem. On the exhaust side where there is no cooling effect from the incoming air/fuel mixture, the guides are critical, because cooling through the stem is especially important for valve longevity. Worn intake guides or ones with too much clearance can also
What’s Wrong With Our Industry
What’s wrong with the engine building industry today? It’s a simple question that has no simple answer. Like many other – if not every – industry facing difficult times, the factors impacting this market are varied, complex and frustratingly hard to pin down. Are the woes of the industry the fault of customers or suppliers?
Valve Seat Installation Procedures
If a valve seat is damaged, cracked, loose, receded or too badly worn to be recut or reground, it can cause a variety of problems: loss of compression, valve burning, valve failure, valvetrain wear and breakage, even head and valve damage if the seat comes loose. For that reason, replacing valve seats is often necessary
The lower intake manifolds on some Ford vehicle models are not fitting correctly after machining
Engine Builders: Some AERA members have reported that the lower intake manifolds on some Ford vehicle models are not fitting correctly after machining. To reduce the likelihood of coolant contamination of engine oil, a revised, thicker intake gasket is now available for the 3.8L and 4.2L Ford car and truck engines. These models have VIN
Conferences And Seminars Offer Many Potential Rewards
Getting away from the day-to-day grind and going to a seminar or conference with fellow shop owners and machinists has rewards that far outweigh the expense, and often may even present new business opportunities. At the Engine Rebuilders Association Tech Expo (AERA) I attended this past April in Indianapolis, a presentation given by John DeBates,
Heavy Duty Technology: Piston Failure Analysis
The air/fuel, coolant and oil systems and relationships between various engine operations and the cylinder liner temperatures are critical to maintaining proper operation of all cylinder components. A variety of conditions can cause excessive piston growth or melting, and each will cause varying results – including catastrophic engine failure. The correct air/fuel ratio balance of
Interruptions To Your Day Compromise Earnings
By now everyone has heard about the electric and natural gas shortage we have been experiencing here on the West Coast. Our power company, Pacific Gas and Electric, sold off all its power plants, and the company has not built any new plants to keep up with the rapid growth of California, particularly in the
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.

The ARC Is Making Headway Promoting The Benefits of Rebuilt Engines
Progress is being made by the Automotive Repower Council (ARC) in its effort to better educate consumers concerning the benefits of repowering, i.e, installing a rebuilt engine, or utilizing machine shop services, compared to purchasing a new or used vehicle or installing a used engine. ARC Chairman, Dave Deegan, recently made a presentation to the
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
On Market Issues: Staying In Touch With The Forces Driving Today’s Market.
The Automotive Parts Rebuilders Association(APRA) incoming chairman, Steve Fallen, knows the importance ofstaying in touch with the forces driving today’s market.What are those market forces? Fallen, 49, who is also presidentof Ennis Automotive, Inc., Ennis, TX, a supplier of rewound stators,rotors and armatures to electrical rebuilders, feels that demandfor rebuilt product is expanding. However, due
LPG Conversions: Renewed Interest In The Use Of LPG (Liquefied Petroleum Gas) And LNG (Liquefied Natural Gas)
The recent move to clean up inner city exhaustemissions has resulted in renewed interest in the use of LPG (LiquefiedPetroleum Gas) and LNG (Liquefied Natural gas) as motor fuels.These fuels are almost pure propane with a little butane present. Tax incentives are being offered to encouragefleet operators to convert to gaseous fuels and more vehiclesare
Washington Way: The Activities Of ACC
Americans have a love/hate relationship withtheir motor vehicles. We love the freedom and mobility the automobilegives us.

The information provided in this article is excerpted from a presentationmade by Doug Barron, Manager of Freedom Battery Design & Application,Delphi Energy & Engine Management Systems. The presentationwas made at last year’s Independent Battery Manufacturers Association(IBMA) Convention in Chicago, IL. Barron’s comments pertain to the future requirements of automotivebatteries. However, they also address the increasing
Labor and the Law
Grit, grime and grease are just a few of theworkplace unpleasantness with which you contend. Employees areexposed daily to hazardous materials such as solvents, paints,cleaning and restoration products, as well as welding fumes. Protecting your employees’ health and safetyis not only the right thing to do, the law requires it. Your failureto be familiar with

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
Cylinder Bore Honing: Main Objective When Refinishing The Cylinders
When an engine is rebuilt, the cylinders usuallyneed attention. Wear tends to create taper in the upper part ofthe cylinder that can reduce ring sealing and increase blowbyand oil consumption if not removed. The cylinder may also be outof round, scored or have other damage that requires correctingbefore a new set of rings will seal
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,
