SERVICE MANUAL INTRODUCTION Introduction DESCRIPTION A unique feature of this lubrication system is the pressure regulating valve. It not only controls the pressure and flow of clean oil released from the oil filters going to the main oil gallery and other critical areas of the engine, but this oil regulator controls the flow of unfiltered oil entering the filters. Excess unfiltered oil is dumped back into the oil pan before it can reach the filters. This added control eliminates the possibility of overloading the filters by dumping oil before filtering, thus adding to oil filter life. CGES- 185-3 *PRINTED IN UNITED STATES OF AMERICA Page 5
