ISM, ISMe, and QSM11 – 003-013   Rocker Lever Housing

The internal engine harness is located inside the rocker housing.

A pass through connector joins the internal and external engine harness. This connector has two clips that can manually be opened to allow separation of the two harnesses. Engines with pass through connectors in the front of the engine have clips on the outside, engines with pass through connections in the rear of the engine have clips on the inside of the rocker housing that require the valve cover to be removed to access.

Disconnect the ground wire connection of the actuator harness (1) from the engine.

Tag the end for future identification.

Remove the external section of the actuator harness.

Use care not to damage the plug as it is being removed from the rocker housing.

NOTE: If high blowby is a symptom, the rocker housing gasket must be inspected before it is removed from the cylinder head.
