CAUTION / NOTICE / HINT
Tech Tips
Use the same procedure for bank 1 and bank 2.
The following procedure is for bank 2.
PROCEDURE
INSTALL SPARK PLUG TUBE
Tech Tips
When using a new cylinder head LH, the spark plug tubes must be replaced.
| *a | Application Width |
| *b | 9.0 to 15.0 mm (0.354 to 0.591 in.) |
Apply adhesive to a new spark plug tube as shown in the illustration.
| Adhesive |
|---|
| Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent |
| Standard Application Width |
|---|
| 1.0 to 3.0 mm (0.0394 to 0.118 in.) |
Note
Install the spark plug tube within 3 minutes of applying adhesive.
| *a | Wooden Block |
| *b | Protrusion Height |
| *c | Cylinder Head LH Top Surface |
Using a hammer and wooden block, install the 3 spark plug tubes to the specified protrusion height.
| Standard Protrusion Height |
|---|
| 73 mm (2.87 in.) |
Note
Do not tap in the spark plug tube more than specified.
Do not start the engine for at least 1 hour after installation.
Be careful not to deform the spark plug tubes.
Be careful not to let adhesive drip into the cylinder head LH.
INSTALL NO. 3 STRAIGHT SCREW PLUG
Using a 10 mm hexagon socket wrench, install 4 new cylinder head screw plug gaskets and the 4 No. 3 straight screw plugs to the cylinder head LH.
Note
Do not apply adhesive to the No. 3 straight screw plug.
The cylinder head screw plug gasket for No. 3 straight screw plug is not same that or water hole gasket for No. 1 straight screw plug.
INSTALL NO. 2 STRAIGHT SCREW PLUG
Using a 14 mm hexagon wrench, install a new cylinder head screw plug gasket and the No. 2 straight screw plug to the cylinder head LH.
INSTALL NO. 1 STRAIGHT SCREW PLUG
Apply adhesive to the 2 No. 1 straight screw plugs.
| Adhesive |
|---|
| Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent |
Note
Install the 2 No. 1 straight screw plugs within 3 minutes of applying adhesive.
Using a 10 mm hexagon socket wrench, install 2 new water hole gaskets and the 2 No. 1 straight screw plugs to the cylinder head LH.
INSTALL VALVE SPRING SEAT
Install the 12 valve spring seats to the cylinder head LH.
INSTALL INTAKE VALVE STEM OIL SEAL
| *a | Gray |
| *b | Black |
| *c | Intake Side |
| *d | Exhaust Side |
Apply a light coat of engine oil to new intake valve stem oil seal.
Note
Make sure to install each valve stem oil seal to the correct side. Installing an intake valve stem oil seal to the exhaust side or installing an exhaust valve stem oil seal to the intake side can cause installation problems later.
Tech Tips
The intake valve stem oil seals are gray and the exhaust valve stem oil seals are black.
| *1 | Valve Stem Oil Seal |
| *a | Correct |
| *b | Incorrect |
Using SST, push in the 6 intake valve stem oil seals to the intake valve guide bush.
Note
Failure to use SST will cause the intake valve stem oil seal to be damaged or improperly seated.
Do not push in the intake valve stem oil seal at an angle.
INSTALL EXHAUST VALVE STEM OIL SEAL
Tech Tips
Use the same procedure as for the intake side.
INSTALL EXHAUST VALVE
| *a | 30 mm (1.18 in.) or more |
Sufficiently apply engine oil to the tip area of the exhaust valve shown in the illustration.
| *1 | Valve Spring Retainer |
| *2 | Inner Compression Spring |
| *3 | Cylinder Head LH |
|
Top Side |
Install the 6 exhaust valves, 6 inner compression springs and 6 valve spring retainers to the cylinder head LH.
Note
Install the inner compression spring with its tapered side facing upward (towards the valve spring retainer).
Install the same parts in the same combination to their original locations.
| *a | Wooden Block |
Using SST and wooden blocks, compress the inner compression spring and install the 6 valve spring retainer locks to the valve spring retainer.
Note
Install the same parts in the same combination to their original locations.
| *a | Plastic Hammer |
| *b | Wooden Block |
Using a plastic hammer, lightly tap the valve stem tip to ensure a proper fit.
Note
Be careful not to damage the valve stem tip.
Be careful not to damage the valve spring retainer.
INSTALL INTAKE VALVE
| *a | 30 mm (1.18 in.) or more |
Sufficiently apply engine oil to the tip area of the intake valve shown in the illustration.
| *1 | Valve Spring Retainer |
| *2 | Inner Compression Spring |
| *3 | Cylinder Head LH |
|
Top Side |
Install the 6 intake valves, 6 inner compression springs and 6 valve spring retainers to the cylinder head LH.
Note
Install the inner compression spring with its tapered side facing upward (towards the valve spring retainer).
Install the same parts in the same combination to their original locations.
| *a | Wooden Block |
Using SST and wooden blocks, compress the inner compression spring and install the 6 valve spring retainer locks to the valve spring retainer.
Note
Install the same parts in the same combination to their original locations.
| *a | Plastic Hammer |
| *b | Wooden Block |
Using a plastic hammer, lightly tap the valve stem tip to ensure a proper fit.
Note
Be careful not to damage the valve stem tip.
Be careful not to damage the valve spring retainer.
