Avoiding Hydraulic Timing Chain Tensioner Trouble Be certain to carefully follow the manufacturer’s recommended torque settings when installing hydraulic (oil pressure fed) timing chain tensioners. Over tightening the tensioner can result in distortion of the tensioner piston bore, which in turn can cause the piston to bind up in the bore instead of doing its
Engine Rebuilding Technical Guide 2011
November 2011 GM 3.4/3.5L Back in 1980, GM introduced an all newV6 that originally displaced 2.8L/173 cubic inches, but over time it grew into a 3.1L/191 cid, a 3.4L/207 cid, a 3.5L/213 cid and finally a 3.9L/237 cid version in 2006. Contributing Editor Doug Anderson takes us through the
Piston Ring Selection In Chrome Plated Cylinders
It is recommended that chrome plated rings not be installed in chrome plated liners under any circumstances. Catastrophic destruction will likely result. Plain cast iron-manganese phosphate coated, or molybdenum rings may be used. It is normally difficult to detect visually in a used cylinder if it is chrome plated or not. If any doubt exists,
How to Grind V8 OHV Engine Cylinder Heads
If the cylinder head is machined and over .010? is removed, the holes in the intake manifold and the cylinder head will not line up when reassembled. To correct this condition, it is necessary to machine surface "B". The amount that must be removed varies with the degree at which the head is machined. The
Caution When Press Fitting Aluminum Timing Gears
When timing gears are subjected to extreme temperatures, the aluminum gears do not return to their original dimensions after cooling. The result is a loose fit between the gears and camshaft. Under no circumstances should aluminum gears be heated with a torch. –Tech Tip courtesy of Hastings Manufacturing
Compression Ring Seating: When is a Piston Ring Seated?
So when is a piston ring actually seated? For a compression ring to seal against the cylinder wall it is important that line contact be established. The sketches below Illustrate cross sections of two popular types used in many ring sets. As can be seen in the illustrations, both the barrel face and the taper

Securing Cam Gears Years ago it came to my attention that the replacement aluminum cam gear used on 4- and 6-cylinder GM inline engines has a tendency to walk off the camshaft. I wanted an easy way to resolve the problem, and here is what I came up with. I grind a notch about 5/16?
How to Check Piston Ring Groove Back Clearance
The piston ring set and the piston must be engineered to complement each other from a standpoint of clearance between the back of the piston ring and the bottom of the piston groove. This clearance is referred to as back clearance. If the clearance is not sufficient, severe engine damage can result when the piston

How Piston Rings Affect Horsepower
The rings seal the pistons to prevent air and oil from being drawn past the rings into the combustion chamber during the intake stroke. During the compression stroke, the rings make sure the air/fuel stays in the combustion chamber and is fully compressed before it is ignited. During the power stroke, the rings prevent pressure

In a recent poll on Engine Builder’s website, we asked our readers how important a dyno is to their business. According to our (admittedly unscientific) results, 44 percent of Engine Builder readers
