Media Frenzy — How Shot Blasting Gets Done
Opinions on which type of blast medium works best for cleaning automotive parts vary among engine builders about as much as the types of media themselves. One rebuilder may say he never uses a particular type of media to blast clean his parts, while another swears by it. Expand that out to the entire rebuilding
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

Bio-Remediation-Managing Munching Microbes
The practice of using microbes to break down and clean up hazardous and unwanted chemicals has been used for many years. However, most people were first introduced to the practice of using oil digesting microorganisms in 1989, when television news broadcasts showed microbes being used in the cleanup of the Exxon Valdez spill, which deposited
The Fit Is In The Finish
Clean, flat and smooth. These three words describe the surface in an engine, not just the head and block. But how clean, how flat and how smooth do the surfaces really have to be to get a good, long lasting seal? It depends on the application. Clean means no dirt, oil, grease or residual gasket
1998 Market Update – CV Shafts
One of the biggest issues still facing rebuilders is the controversyover the pros and cons of grinding CV joints.

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
Why Parts Get Coated
I never would have believed you could get those kind of resultsfrom a glorified paint job. With those words, another skeptic(in this case, a NASCAR Winston Cup engine builder) had come toaccept the value of special coatings applied to engine components. At the time, such skepticism was not totally unwarranted. Likeany emerging technology, the coating
