The intake manifold also includes an integrated oil pump, which is located at the front of the manifold. This oil pump is responsible for supplying oil to the engine's upper end, ensuring proper lubrication. The oil pump is designed to be robust and reliable, with a durable cast aluminum housing and a precision-machined impeller.

The Oldsmobile 400 425 455 L-67 Low-Rise Intake Manifold, 1-147-097, is a high-quality, performance-oriented part that delivers excellent airflow and reliability for Oldsmobile V8 engines.
