CYLINDER HEAD GASKET (for Bank 1) > INSTALLATION |
for Preparation Click here
1. INSPECT CYLINDER HEAD SET BOLT |
Using a vernier caliper, measure the diameter of the elongated thread at the measuring point.
- Standard diameter:
- 10.85 to 11.00 mm (0.427 to 0.433 in.)
- Minimum diameter:
- 10.6 mm (0.417 in.)
- HINT:
- If a visual check reveals no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the lowest diameter.
2. INSPECT CYLINDER HEAD SUB-ASSEMBLY LH |
Using a precision straightedge and feeler gauge, measure the warpage of the contact surfaces of the cylinder block and manifold.
- Standard warpage:
Item Specified Condition Cylinder head lower side 0.05 mm (0.00197 in.) Intake side 0.08 mm (0.00315 in.) Exhaust side 0.05 mm (0.00197 in.)
- Maximum warpage:
- 0.10 mm (0.00394 in.)
Using a dye penetrant, check the intake ports, exhaust ports and cylinder surface for cracks.
If cracked, replace the cylinder head.
3. INSTALL CYLINDER HEAD GASKET LH |
Check the piston protrusions for each cylinder.
Clean the cylinder block with solvent.
Set the piston of the cylinder to be measured to slightly ATDC.
Place the cylinder head gasket on the cylinder block surface with the front face of the Lot No. stamp upward.
- NOTICE:
- Be careful of the installation direction.
- Make sure that no oil is on the front end (indicated by the arrows) of the cylinder head gasket.
4. INSTALL CYLINDER HEAD SUB-ASSEMBLY LH |
Place the cylinder head on the cylinder block.
- NOTICE:
- Ensure that no oil is on the mounting surface of the cylinder head.
- Gently place the cylinder head in order not to damage the gasket with the bottom part of the head.
- HINT:
- The cylinder head bolts are tightened in 3 progressive steps.
Apply a light coat of engine oil to the threads and under the heads of the cylinder head bolts.
Step 1:
Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 10 cylinder head bolts with the plate washers in several steps, in the sequence shown in the illustration.
- Torque:
- 36 N*m{ 367 kgf*cm , 27 ft.*lbf }
Step 2:
Mark each cylinder head bolt head with paint as shown in the illustration.
Tighten the cylinder head bolts another 90° in the sequence shown in step 1.
Step 3:
Tighten the cylinder head bolts an additional 90° in the sequence shown in step 1.
Check that the painted marks are now facing rearward.
Install and uniformly tighten the 2 bolts in the sequence shown in the illustration.
- Torque:
- 21 N*m{ 214 kgf*cm , 15 ft.*lbf }
5. INSTALL VALVE STEM CAP |
Apply a light coat of engine oil to the valve stem caps.
Install the 16 valve stem caps to the cylinder head.
6. INSTALL VALVE LASH ADJUSTER ASSEMBLY |
Inspect the valve lash adjuster (Click here).
Install the 16 lash adjusters to the cylinder head.
- NOTICE:
- Install the lash adjuster at the same place it was removed from.
7. INSTALL NO. 1 VALVE ROCKER ARM SUB-ASSEMBLY |
Apply engine oil to the lash adjuster tips and valve stem cap ends.
Install the 16 valve rocker arms as shown in the illustration.
8. INSTALL CAMSHAFTS (for Bank 1) |
Install the camshafts (Click here).
9. INSTALL EXHAUST MANIFOLD SUB-ASSEMBLY LH |
Install the exhaust manifold LH (Click here).
