# METHOD OF REMOVING ROCKER ARM COVERS

#### VEHICLES AFFECTED: 1984-86 'A-F-N-P-X' Cars, S/T Trucks and 'M' Vans With 2.5L L4 Engines

Tools have been developed to remove the rocker arm cover from 2.5L L4 engines without damage. The essential tool is Kent Moore J-34144-A.

To use these tools, remove the PCV hoses and grommets from the rocker arm cover and insert a tool into a PCV opening as shown in the illustration. Turn the tool 90 degrees to place the lips under the bottom of the baffle, then slide the tool to the right side, orrear of the engine, placing the end of the screw over a cylinder head bolt. Turn the screw handle to extend the screw from the tool until snug. Repeat this procedure with the second tool. Turn both screw handles simultaneoulsy until the cover breaks loose.

Remove the tools from the cover by turning each 90 degrees to disengage the lips from the baffle and take the tools out of the PCV openings.

Use applicable labour time and operation number.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
