The racing oil community has been very busy this past year. This is much more satisfying to an old “oilhead” who has seen years where there were no new racing oil developments. Racers and engine builders traditionally focus more on improvements in hard parts, because that’s what they understand best....
The National Street Rod Association (NSRA) provides the best definition of what street rods are all about. “By definition a street rod is an automobile of 1948 or earlier manufacture which has undergone some type of modernization to include any of the following; engine, transmission, interior refinements, and any other...
I asked if any of them had any V8 models coming in for timing belts so I could get some pictures of the process. Either a blank stare, or a question like: “What Toyota V8?” was the general response. The idea that there was a Toyota V8 needing a timing...

But if I were a professional engine builder, or even a highly competent amateur engine builder, one of the first things I would do is learn as much as possible from the smartest people in the business. While we at Engine Builder magazine provide countless articles on the subject and...
Since most people who are involved in racing do not run in NASCAR Sprint Cup, IndyCar or NHRA Top Fuel, we think that it is fair to say anything below these high profile professional racing series is a large group of grassroots racers who support the industry through the dollars...
Munro had a problem with melting his cast pistons so he kept trying to develop his own out of melted down GM pistons. Today’s piston makers use a little more modern techniques, but the principle is the same: try, test and improve. On the outside, pistons tend to look the...
The fuel system of a modern computer-controlled fuel injected engine is so reliable that it seems to be almost maintenance free, but these modern fuel injected engines have injectors that become flow restricted or “dirty” with use. This means that if you expect the engine you build to perform like...
In that discussion we hashed over the disparity in coefficients of expansion between cast iron and aluminum (that caused a revolution in head gaskets around the time of the Cadillac 4.1L). We discussed surface conditions and how that affects gaskets and scrub. We discussed gasket coatings and how they remain...
The light turns green and the truck bellows out a plume of black smoke and in a flash all you see are the taillights. You’re struck that diesel trucks have really made an improvement over the past fifteen years. It’s amazing when you realize that a Corvette would have a...
By now, most shops should have implemented their information security programs and taken steps to ensure compliance with the Safeguards Rule. If you have not, we recommend taking steps to get in compliance immediately. If you have, it’s still important to periodically review and assess your program to ensure you...
Over time, erosion and corrosion can eat away at the metal resulting in compression leaks, elevated valve temperatures and sometimes valve failure. If a valve seat insert doesn’t have the correct amount of interference fit in the cylinder head, it’s possible the seat may loosen up and fall out damaging...
Unless you’re starting with all new parts, cleaning is as important to your engine build as disassembly, inspection, machining and reassembly. Without taking the cylinder heads and engine blocks down to bare metal, you can’t properly inspect the castings for cracks, wear and other defects. For something so important, proper cleaning...
The function of a cylinder bore is fairly simple yet quite demanding. The bore is nothing more than a cylindrical void which contains the engine’s air/fuel mixture as it undergoes compression and combustion. The walls of the cylinder have to be strong enough and rigid enough to withstand...
Since diesel engines ignite by using the heat of combustion, they usually need help when the climate changes to the cold of winter. Veteran owners of “old school” diesel engines understand what I’m talking about when I mention the “one-minute of silence.” This was the time every morning when you...
