Abstract
A method of covering a valve and rocker arm area of an internal combustion engine is disclosed. The engine includes an engine exhaust outlet and an engine air inlet. The method includes the step of providing a valve cover assembly which includes a housing having a chamber defined therein, and a conduit positioned in the chamber. The conduit connects the engine exhaust outlet to the engine air inlet. The method also includes the step of securing the valve cover assembly to the engine so that the cover portion of the valve cover assembly covers the valve and rocker arm area. The method further includes the step of advancing exhaust gas from the engine exhaust outlet to the engine air inlet through the conduit. The method still further includes the step of advancing fluid through the housing so as to cool the conduit. A valve cover assembly for use on an internal combustion engine is also disclosed.
