ABSTRACT:
A reciprocating piston engine in which oil cooling is provided by a hollow oil jet assembly located accurately by a location tool and pressed into position in a bore in the crankcase of the engine. Accurately drilled and aligned jet passages are formed in the assembly which is then fitted into position with good accuracy to enable accurate direction of a jet or jets of cooling oil to a desired point or points on the underside of a piston.
