Rebuilding The Ford 2.0L
The old 1.9L was modified and upgraded in the process of making it into the 2.0L. The new engine was bored and stroked, it had siamesed cylinders that made the block stronger and quieter, the crank had four more counterweights that made it run smoother, and it had domed pistons for more compression. The
Coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines
Engine Builders: The AERA Technical Committee offers the following information regarding coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines due to failure of the intake manifold gasket. GM has redesigned a new intake manifold gasket (p/n 89017279) to reduce the chance of failure. The material used in
Rebuilding the Ford 5
Doug Anderson is president of Grooms Engines, Parts, Machining, Inc., located in Nashville, TN. He has authored numerous technical articles on engine rebuilding for Engine Builder magazine for more than 15 years. Anderson has also made many technical presentations on engine building at AERA and PERA conventions and seminars. The 330/5.4L Ford engine was introduced
Repair Of Worn Cam Bearing Housing Bores For Detroit Diesel 11.1l And 12.7l Diesel 60 Series Engines
Engine Builders: The AERA Technical Committee offers the following information regarding the possible repair of worn cam bearing housing bores for Detroit Diesel 11.1L and 12.7L diesel 60 Series Engines. These engines use an overhead camshaft design with seven individual location precision bearing inserts. Over time, the bearing bores may become worn oversize or out-of-round,
Ohc Journal Repairs
One of the advantages of an overhead cam cylinder head is that it eliminates the need for certain valvetrain components. Mounting the camshaft in the cylinder head rather than the engine block eliminates the need for lifters and pushrods. On some OHC engines, the cam lobes run directly atop the valve stems. On others, cam
Where Should The Cam Bearing Oil Hole Be Located On A 3400 Series Cat Diesel?
A: The AERA Technical Committee offers the following information regarding cam bearing oil hole location for 3400 series Caterpillar diesel engines and installation of all cam bearings for these engines. This bulletin should be used, and service manuals published before 1985 should not be used. The correct location for the oil hole in the camshaft bearing
Rebuilding the Ford 4.6L SOHC Engine
The 4.6L was lower, shorter and lighter than the 302, but the base engine made more power than the 302, got better fuel economy and passed all the emission tests without a thermactor pump. Ford called it its “modular” engine because it was part of a whole new family of engines that were intended to
Porting For Performance The Science of Horsepower
Air flow makes horsepower. The more cubic feet per minute (cfm) of air that flows through the intake ports and into the combustion chambers, the more horsepower the engine makes. A larger carburetor or throttle body, bigger valves, a high-lift, long-duration camshaft, three-angle valve job and exhaust headers are all performance enhancements that increase airflow
Engine Crack Detection Technology
It doesn’t matter if you’re rebuilding a high mileage engine and reusing salvaged components or using brand new parts right out of the box – any highly stressed component or casting that has to withstand high loads, temperatures and/or pressures should always be inspected to make sure it is free from cracks or other defects
Rebuilding The Ford 3.8L Engine
They needed an economy engine that would fit in their new cars, and they needed it fast. They had a couple of old inline sixes and a small German V6, but none of them were designed for fuel economy or the coming emissions standards, and the 250 cid engine was so tall that it wouldn’t
Ford 4.0L V6 Engine
The original 2.6L engine was replaced by the 2.8L, which was upgraded to the 2.9L and then finally bored and stroked to make it into the 4.0L that was used in the Rangers, Aerostars and Explorers starting in 1990. It was replaced by a SOHC engine from this same family at the end of model
Rebuilding the GM / Chevy 2.2L Engine
Unfortunately, this four cylinder, pushrod motor didn’t have nearly enough horsepower, so Buick, Oldsmobile and Pontiac all opted for the 1.8L SOHC Opel engine from Brazil for most of their “J” cars, and Chevy promptly made its new engine into a 2.0L/121 cid that delivered more power in 1983. The 2.0L was upgraded in 1987
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
Rebuilding the New Chevy 262
This enabled GM to shorten the development process dramatically because it was able to adapt a proven design. But it also allowed it to share a lot of the existing tooling from the V8 production lines so the engines could be on the road sooner. The original 200 V6 that came out in 1978 was
Rebuilding the Chevrolet LT1 Engine
Compared to the 1991 Chevy 350 L98 with TPI, the LT1 made 20 percent more horsepower, got better fuel mileage, and had a much broader torque band with 90 percent of its peak torque available from just over 1,000 rpm all the way up to nearly 6,000 rpm. GM Powertrain accomplished all of this by
Heads Up: Rebuilding Aluminum Cylinder Heads
In our last article (Automotive Rebuilder, July, 1999 issue page 54) we discussed how to check valve stem to guide clearances and the methods used to replace valve guides and seats. Camshaft clearances and techniques used to bring clearances to within specification were also covered. In this article we will cover the final assembly of
Valve, Guide and Seat Repair Options
Valve, guide and seat repairs are the cornerstones of rebuilding cylinder heads. It makes no difference if the head is a 350 Chevy or one with dual overhead cams and four-valves-per-cylinder. The basics of refinishing the valves, guides and seats are essentially the same. The newer high tech heads will usually have smaller parts, the
Rebuilding the Chevrolet LT1 Engine
Although it shared many common dimensions, looked much the same and even had a few common parts, it was totally redesigned to provide more power with lower emissions and better fuel economy. Compared to the 1991 Chevy 350 L98 with TPI, the LT1 made 20% more horsepower, got better fuel mileage, and had a
Rebuilding Toyota 3.0L V6 Engine
In 1988 Toyota introduced its first V6. Most of the information that follows applies to the 3.0L version used in Toyota’s truck applications. The 3.4L is still fairly new to the aftermarket at this point. 3VZ-E – 3.0L SOHC V6 – ’88-’95 The 3VZ-E was also introduced for the 1988 model year on Toyota 4×4
Rebuilding The GM Quad 4
The Quad 4 had four valves per cylinder, tuned intake and exhaust manifolds, no distributor, no plug wires, lightweight rods and pistons to reduce shaking forces, and a crank with eight counterweights that was designed to reduce noise, vibration and harshness (NVH) and bearing wear. It didn’t have an A.I.R. pump or an EGR system,
