One of the most successful and longest-lived projects of Cosworth has been its Indy car engine program. In 1975; Cosworth developed the DFX, by destroking the engine to 2.65 L and adding a turbocharger, the DFX became the standard engine to run in IndyCar racing, ending the reign of the Offenhauser, and maintaining that position until the late 1980s.
In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be ...
A long block engine replacement typically requires swapping out parts from the original engine to the long block. These parts can include the oil pan , timing cover , valve covers , intake manifold , emission-control parts, carburetor or fuel injection system, the exhaust manifold(s) , alternator , starter , power steering pump (if any), and ...
The common valve spring system is satisfactory for traditional mass-produced engines that do not rev highly and are of a design that requires low maintenance. [1] At the period of initial desmodromic development, valve springs were a major limitation on engine performance because they would break from metal fatigue.
An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.

The most common use of a rocker arm is to transfer the motion of a pushrod in an overhead valve (OHV) internal combustion engine to the corresponding intake/exhaust valve. In an OHV engine the camshaft at the bottom of the engine pushes the pushrod upwards. The top of the pushrod presses upwards on one side of the rocker arm located at the top ...
