Can You Keep Up With The Changes In The Industry?

In this fast-paced world, keeping up with any industry can be very trying. Keeping up with the latest trends can be the difference between success and failure. Those businesses that remain successful are those that continually stay at the forefront of their chosen field. The engine rebuilding business has seen tremendous change in the past

The Angle On Valve Seats

Valve seats seem to be a fairly simple engine component but they play a critical role in sealing compression and cooling the valves. When a seat becomes worn, it may leak compression and allow the valve to run hotter than normal. The same thing can happen if the seat is out-of-round or has lost its

New Clean Diesel Technology

With gasoline prices in the U.S. bouncing around the two dollars per gallon mark, record high oil prices and growing uncertainty over the price and availability of future oil supplies, any new technology that can give consumers more bang for their buck should be welcomed. Domestic vehicle manufacturers have virtually abandoned further development of electric

Bedplate torque sequence for a Chrysler 4.7L

What is the bedplate torque sequence for a Chrysler 4.7L? My manual doesn’t seem to list all the fasteners. The AERA Technical Committee offers the following information regarding the main bearing cap/bedplate bolt torque and sequence for 1999-2004 Chrysler 4.7L VIN N engines. This engine uses multiple fasteners at many different locations to secure the

PERA’s Core’s Corner

Some months back (December 2003 Engine Builder, to be exact), I wrote about some of the identification features of the Gen III GM V8 engines. Considering that the Gen IV with DOD (Displacement on Demand) is about to be released, this is probably a good time to go over a few other things that you

Ford Timing Chains and Belts

So if a customer is driving a vehicle that is more than 5 or 6 years old, he may be driving on borrowed time if the timing belt has not been replaced. The risk of belt failure goes up sharply once a belt surpasses its recommended replacement interval, which for most Ford applications (except the

Rebuilding The Ford 3.0L V6

The 3.0L Ford pushrod motor has been around for nearly 20 years. It was originally introduced back in 1986 and millions of them have been installed in a wide variety of front and rear wheel drive cars and trucks since then. It’s been used in several FWD applications including the Taurus/Sable, the Tempo/Topaz and the

What head gasket issues does a Toyota 2.2L have that I should be concerned with?

The AERA Technical Committee says that loss of engine coolant has been reported on 1997 Toyota 2.2L 5SFE engines in various amounts. In most cases, there are limited signs of this leakage on the ground directly below the engine compartment after it has set for a long period of time. Depending on the production date

Getting To The Bottom Of The Great Ford Cover-Up

Lately I’ve been noticing an increase of instances where an engine may be the same from one year to the next, with the exception of one major change: the front cover, primarily with SOHC or DOHC engines. Well, we are back this month with an old friend: the Ford 4.6L SOHC engine family and its

Big-Inch Cadillac’s

While some engines are relatively rare in machine shops, the big Cadillacs have remained a consistent source of income. These engines are Cadillac’s last big hurrah at traditional big-cube, flagship GM engines. Surprisingly, they are also a scaled-down version of a V-12 engine that made it through early production and road-testing before being scrapped as

I replaced a ’97 Ford 302 with a 351 Windsor, but the thrust bearing failed after only 200 miles. What gives?

A. We have all seen the thrust bearing failures in the Ford 302/5.0L engine applications. Many if not most of them have occurred due to the insufficient depth of the pilot hole for the torque converter in the rear of the crankshaft when used in conjunction with an overdrive transmission, and in particular with the

Washington Way

Finding and retaining good service technicians and other employees has become an increasing problem in the parts and service aftermarket. There just aren’t enough competent individuals available and the cost of salary and benefits for all employees keeps increasing. Small firms, in particular, may have problems because of the ever-increasing costs of competitive salaries and

Valves, Retainers & Springs

New materials, improved designs and lower prices (at least for some valves). That pretty much sums up what’s going on with valves, retainers and springs today. These are extremely important parts in every engine because of their impact on engine performance, durability and cost. Satisfying demand is the key. Rick Simko of Elgin Industries, Elgin,

Guide and Seat Equipment

Cylinder head work has been and should continue to be a profit center for engine builders. Heads almost always require guide and seat work to restore compression and oil control. This includes drilling, reaming and replacing valve guides, removing worn, loose or damaged valve seats, cutting new seat counterbores, and machining valve seats. For performance

Bad For The Auto Industry, Good For Rebuilding

The headline in the Dallas Morning News caught my eye: “New Car Customers With Negative Equity Are Growing Problem For Auto Industry.” The words “negative” and “problem” are well-recognized around this segment of the “auto industry” so, of course, I read on to see how this story would impact the Engine Builder reader. To my

I’m looking for an oversize O.D. cam bearing for a Cummins L10. Is there anything available?

It has recently been announced that there are oversize outside diameter cam bearings available for 1985-2003 Cummins L10 & M11 engines. This new bearing will allow a single repair operation to many engine blocks, which will put many unserviceable engine blocks back into service. These engines have been prone to engine failure related to cam

PERA’s Core Corner

In this month’s “Core Corner” I am addressing a potpourri of different issues – some old, some new, but all of them offer something that will keep you out of the “Do Over” column and, of course, profitable. I got the idea from my wife some weeks ago while accompanying her (being dragged) to a

Crankshafts and Bearings – Keeping the Relationship Strong

Today’s engines typically have very tight tolerances everywhere and the crankshaft bearings are no exception. The truer the crank is in its alignment with the mainline and cylinder bore, the tighter the tolerances can be. Bearings and mainline bores must be very precise because during operation the crankshaft is not actually straight: it is elastic.

Researching the Rebuilding Market for Multi-Valve Cylinder Heads

Cylinder head work has provided a good income for many of our readers over the years. All engines eventually need a valve job and guide work if they accumulate enough miles. Head work may also be needed if an engine overheats and blows a head gasket, if the head develops a crack, or an OHC

2004 AETC Conference

The 14th annual Advanced Engine Technology Conference (AETC) saw a return to the Antlers Adam’s Mark, in downtown Colorado Springs, CO, Jan. 8-11. The return to this facility, though higher priced than those used in the recent past, was requested by a poll of last year’s attendees because of the higher quality of the hotel
