Cylinder Head Removal and Installation
Installation
1. Set The Crankshaft To Top Dead Center
1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with the pointer (B) on the engine block.
2. Cylinder Head Assembly
1. Install a new coolant separator (A) in the engine block whenever the engine block is replaced.
2. Clean the cylinder head and the engine block surface.
3. Install the new cylinder head gasket (A) and the dowel pins (B) on the engine block. Always use a new cylinder head gasket.
4. Install the cylinder head on the engine block.
5. Measure the diameter of each cylinder head bolt at point A and point B.
6. If either diameter is less than 10.6 mm (0.417 in), replace the cylinder head bolt.
7. Apply new engine oil to the threads and under the bolt heads of all cylinder head bolts.
8. Torque the cylinder head bolts in sequence to 39 Nm (4.0 kgfm, 29 lbfft). Use a beam-type torque wrench. When using a preset click-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it from the first step.
9. After torquing, tighten all cylinder head bolts in two steps (90 ° per step) using the sequence shown in step 8. If you are using a new cylinder head bolt, tighten the bolt an extra 90 °.
NOTE: Remove the cylinder head bolt if you tightened it beyond the specified angle, and go back to step 6 of the procedure. Do not loosen it back to the specified angle.
3. Rocker Arm Assembly
1. Clean and dry the No. 5 rocker shaft holder mating surface.

NOTE:
* Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A).
* If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
3. Install the lost motion assemblies (A) in the cylinder head.
NOTE: Apply new engine oil to the lost motion assembly.
4. Insert the bolts (B) into the rocker shaft holder, then install the rocker arm assembly (C) on the cylinder head.
5. Remove the bolts from the rocker shaft holder.
4. Camshaft

1. Install cam chain guide A and the tensioner arm (B).
2. Install cam chain guide B.
8. Cam Chain Auto-Tensioner
1. Compress the auto-tensioner when replacing the cam chain. Remove the pin (A) from the auto-tensioner that was installed during removal. Turn the plate (B) counterclockwise, to release the lock, then press the rod (C), and set the first cam (D) to the first edge of the rack (E). Insert the 1.2 mm (3/64 in) diameter pin back into the holes (F).
NOTE: If the chain tensioner is not set up as described, the tensioner will be damaged.
2. Install the auto-tensioner.
3. Remove the pin from the auto-tensioner.
4. Remove the camshaft lock pin set.
9. Cam Chain Case
1. Check the chain case oil seal for damage. If the oil seal is damaged, replace the chain case oil seal.
2. Remove the old liquid gasket from the chain case mating surfaces, the bolts, and the bolt holes.
3. Clean and dry the chain case mating surfaces.
4. Apply liquid gasket (P/N 08718-0004 or 08718-0009) to the engine block mating surface of the chain case and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.
* Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A) and (B).
* Apply a 3.0 mm (0.118 in) diameter bead of liquid gasket along the broken line (C).
* If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
5. Apply liquid gasket (P/N 08718-0004 or 08718-0009) to the oil pan mating surface of the chain case, and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.
