How are the rocker shafts oiled on a top fuel donovan engine?

In Top Fuel Donovan engines, the rocker shafts are pressure-oiled. The engine utilizes a high-pressure oil pump that ensures a continuous supply of high-pressure oil to the rocker shaft assemblies. This pressurized oil is then directed through dedicated oiling passages or lines to directly lubricate the rocker shafts and related components. The precise design and configuration of the oiling system may vary depending on the engine builder and specific Donovan engine model.
