Ford 390 V-8 Lubrication System Diagram - Oil Flow Schematic (Fig. 11)
Schematic diagram of the 390 V-8 engine lubrication system showing oil pump, galleries and rocker-arm oiling paths.
This is a scanned page from an automotive service manual showing Figure 11, a cutaway schematic of the lubrication system for the Ford 390 V-8 engine (illustration code A2023-D). The diagram depicts the engine block in cutaway view with directional arrows tracing the oil circulation path: oil is drawn up by the oil pump at the bottom of the engine, passes through a full-flow oil filter (shown in cross-section with internal flow arrows), and is distributed through the main oil gallery along the top of the block. From the gallery, branch passages feed the five main crankshaft bearings and the camshaft bearings, with additional passages routing oil up toward the valve train (the cropped page heading references lifter operation). The front of the engine, including the fan and pulley assembly, is shown for orientation. Surrounding body text from the manual page and the reverse side bleeds through faintly and is largely unreadable, though a heading referencing the cooling system is discernible. A reader can learn the general oil flow routing of the 390 V-8 — pump, filter, main gallery, bearings — from this single illustration.
