Performance Rocker Arms
Pushrod engines new and old are still a hot topic. Overhead cams have been used in many European and Asian engines for years, so when Ford opted to go the overhead cam route with their 4.6L V8 engine, some predicted pushrod engines were on their way out. But, GM stuck with the pushrod design for
Diesel Cranks and Connecting Rods
The demand for mid-size diesel performance products continues to grow. There tends to be two sides of the mid-size diesel spectrum: on one side there is street performance and on the other there is all-out race. Street performance diesels deal mainly with engine parts that are primarily for bolt-on applications and can make great power
Future of Engine Building: Industry Forecast
The more things change, the more they stay the same As we entered into the new millennium, the industry had an optimistic, yet cautious outlook as to what the future held for the production engine remanufacturers and custom engine rebuilders. When we asked various industry insiders this month to look into their crystal spheres, past
Service Issues on Ford 4.6L SOHC & DOHC Engines
In 2005, Ford introduced a three-valve (3V) SOHC version of the 4.6L for the newly restyled retro-look Mustang. Major changes included the use of two intake valves and one exhaust valve per cylinder to increase air velocity, torque and power, variable cam timing and a weight-saving aluminum cylinder block. Ford’s overhead cam 4.6L V8 engine has been
Powertrain Products; Problems With Ford 5.4L Truck Engines
The proper rebuild must contain not only new phasers, but also resized and machined camshaft bores, with the installation of OEM sized cam-bearings or an oversized camshaft with machining to zero runout (along with the traditional re-manufacturing process) Powertrain Products Inc., a national distributor of rebuilt automotive engines, reports on an alarming trend in Ford 2004-2010 trucks, equipped

Diagnosing Engine Noise Under The Hood Of A Ford F-150
This article is about diagnosing a mysterious engine noise in a 1989 Ford F-150 pickup equipped with the venerable 5.0L or 302 cubic-inch V8 engine following a rebuild. Most of us working in the automotive service trades are very familiar with Murphy’s Law and how it affects our shop’s cost of doing business. Murphy’s Law
Chevy 3.1L Cam Bearing Bore Issues
Some of the later roller cam 3.1L blocks for the ’93-’94 Chevy VIN M are showing up with oversize cam bearing bores that appear to have been caused by spun cam bearings. If a new cam bearing is installed in a bore that has been damaged, it will spin in the block, cut off the

3 Practical Tips for Assembling a Race Engine
Keeping clean, high quality oil in the engine is insurance against lubrication related problems – because what you can’t see, can hurt you. A human hair is about 80 microns wide, and the smallest particle size you can see with a naked eye is about 40 microns. That seems pretty small. Can something so small
GM Belt Tensioner May Cause Supercharger Failure
Problem: Premature failure of supercharger bearings. Cause: When the belt tensioner starts to fail, belt tension increases dramatically. This tension shows up as side-loading in the supercharger rear bearing. Solution: Periodic inspection of the belt tensioner should be part of the regular maintenance routine. Before operating the replacement supercharger, the tensioner must be inspected and

How to See Through Pistons for Clearance With the advent of longer stroke crankshafts, one inch plus lift camshafts, raised camshaft locations, lifter angles, bore spacing, etc., exact camshaft lobe and connecting rod clearance may not be able to be determined from looking up from the crankcase area of the block. To see through the
Racing Oils
The latest API-certified SN and ILSAC GF-5 motor oils are fine for everyday driving in late model vehicles, but most off-the-shelf motor oils (even many synthetics) come up short in the anti-wear department in a racing application – especially if the engine is running a flat-tappet cam or a radical roller cam with a lot
Cleaning Engine Blocks & Engine Cylinder Heads
Cleaning engine blocks and cylinder heads is just as important as the machining operations you will perform on the castings. You can’t do a thorough job of inspecting these parts if they are dirty, greasy or covered with paint or corrosion. Checking for cracks in cast iron heads and blocks requires a clean surface for
Built for Auction
The criteria for selecting Engine Builder magazine’s inaugural “Performance Engine Builder of the Year” included much more than the ability to put together race-winning engines. Things like community involvement and the support of training and education were part of the mix. To be sure, our 2012 award winner, Ed Pink Racing Engines of Van Nuys,
Oiling System Technology
Oil is the lifeblood of every engine. Any significant loss of oil pressure can destroy an engine in a split second so the oiling system must provide a constant supply of oil under all operating conditions. With performance engines, keeping the engine lubed with a steady supply of oil can be a challenge because
Sleeves & Liners
I often hear customers ask about the difference between a sleeve and a liner. It’s an understandable question. Automotive guys call them sleeves and diesel guys call them liners. And while they may be used for similar purposes, the perception of what they do may be very different among different groups. Many automotive enthusiasts understand
Racing Oils
Performance engines built for racing deserve the best possible lubrication. Ordinary street oils don’t cut it on a race track. By Larry Carley The latest API-certified SN and ILSAC GF-5 motor oils are fine for everyday driving in late model vehicles, but most off-the-shelf motor oils (even many synthetics) come up short in the anti-wear
Motor Oil Fact or Fiction
1. Synthetic motor oil is too slippery. It causes roller bearings to slide instead of roll, and that causes the bearings to fail. Fact or Fiction? – Fiction If you have ever flown on a jet airplane, you have enough experience to debunk this myth. All jet turbine engines utilize rolling-element bearings, and every jet
