TMeyer Oil Flow Modification Diagram - 1/4" Pipe Plug & 5/16" Drill Oil Passage

This document is an annotated color photograph illustrating an engine oiling system modification. The photo shows a section of an engine block around a bearing/bushing bore (likely the distributor or cam area) with overlaid arrows indicating oil passage routing. A legend identifies two flow paths: red lines labeled 'Original Oil flow' show the factory oil routing, and yellow lines labeled 'TMeyer Oil flow' show the modified routing. Two callouts describe the required modifications: one oil passage is blocked with a '1/4" pipe plug' (marked in black on the photo), and another passage must be enlarged, with the instruction 'Drill out to 5/16"'. The image serves as a visual guide for redirecting oil flow within the block, presumably to improve lubrication, by comparing the stock passage path against the modified TMeyer path. No year, model, engine designation, torque specifications, or part numbers are visible in the image; the only textual content consists of the two legend entries and the two modification callouts. A reader can learn where to install the pipe plug and which passage to drill to convert from the original oiling scheme to the TMeyer oiling scheme.
