Usage:
The C7 from the factory has the crankcase breather on the side of the block, next to the cam followers. (A location inside the engine where there is a lot of splashing - This complete breather assembly was blocked off, so it no longer functions. The new engine breather is mounted on the top of the valve cover, where there is no oil splashing. Location of the injection actuation pressure control valve. SMCS Code: 1925-081. System Operation Description: Use this procedure under the following situation: Use the following information in order to troubleshoot. The system when there is an active code: 164-02 Injection Actuation Pr Sensor Erratic (15).
