- Install the camshaft.
- Coat the camshaft lobes and journals with high viscosity oil with zinc (GM P/N 12345501) or equivalent.
- Handle the camshaft carefully in order to prevent damage to the camshaft bearings.
- Install the thrust plate bolts.
- Install the camshaft position sensor.
Important: If you install a new camshaft, replace all of the valve lifters.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
