Cylinder Head - Installation

INSTALLATION










1. Clean all sealing surfaces of engine block and cylinder heads. Engine Gasket Surface Preparation
2. Position new gasket(1) on engine block. The left bank gasket is identified with the "L" stamped in the exposed area of the gasket located at front of engine. The right bank gasket is identified with a "R" stamped in the exposed area of the gasket also, but is located at the rear of the engine (2).










3. The cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts must be replaced.
4. Necking can be checked by holding a scale or straight edge (2) against the threads. If all the threads do not contact the scale (2) the bolt should be replaced.





5. Tighten the cylinder head bolts 1-8 in the following sequence. Using the 4 step torque turn method, tighten according to the following values:
- Step 1: Bolts 1 - 8 to 61 Nm (45 ft. lbs.)
- Step 2: Bolts 1 - 8 to 88 Nm (65 ft. lbs.)
- Step 3: Bolts 1 - 8 (again) to 88 Nm (65 ft. lbs.)
- Step 4: Bolts 1 - 8 turn an additional 1/4 Turn. (Do not use a torque wrench for this step.)

NOTE: Bolt torque after 1/4 turn should be over 122 Nm (90 ft. lbs.). If not, replace the bolt.

6. Inspect push rods and replace worn or bent rods.
7. Install the push rods.
8. Install the rocker arm and shaft assemblies. Valve Rocker Arm - Installation

11. Install new O-ring on dipstick tube. Install dipstick tube assembly.
12. Install the spark plugs.
13. Install upper and lower intake manifolds. Intake Manifold - Installation
14. Fill the cooling system. Service and Repair
