For 1990-2009 cars

1. Install the oil pump cover to the balance shaft housing.
2. Install the oil pump bolts to the balance shaft housing.

Tighten
Tighten the long oil pump to balance shaft housing bolts to 12 N·m (106 lb in).

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.

Tighten
Tighten the short oil pump cover to oil pump housing bolt to 10 N·m (89 lb in)

3. Install the balance shaft chain guide.

Important: A brass feeler gauge needs to be used to ensure correct measurements are obtained. If a steel gauge is used, it will not bend to conform to the guide and will cause incorrect measurements.

4.1. | Inserting a 1 mm (0.040 in) brass feeler gauge between the chain guide and the chain.

4.2. | Press the guide against the chain. Use about three pounds of force.

4.3. | Tighten the chain fastener bolt.

Tighten
Tighten the bolt to 13 N·m (115 lb in).
