Reassembly [12/2013 - ]: Procedure
- INSTALL SPARK PLUG TUBE
HINT:
When using a new cylinder head sub-assembly, the spark plug tubes must be replaced.
- 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.
- Be careful not to deform the spark plug tube.
- Do not expose the spark plug tube to engine oil for at least 1 hour after installing it.
- Using a wooden block and hammer, tap in the spark plug tube.
*a Cylinder Head Casting Surface Standard Protrusion Height
112 mm (4.41 in.)
NOTE:To avoid tapping in the spark plug tube too far, measure the protrusion height while tapping it.
- Apply adhesive to a new spark plug tube as shown in the illustration.
- INSTALL CYLINDER HEAD STUD BOLT
- INSTALL NO. 1 STRAIGHT SCREW PLUG
- INSTALL NO. 2 STRAIGHT SCREW PLUG
- INSTALL VALVE SPRING SEAT
- Install the valve spring seat to the cylinder head sub-assembly.
- INSTALL VALVE STEM OIL SEAL
- Apply a light coat of engine oil to new valve stem oil seals.
*a Intake Valve Stem Oil Seal *b Exhaust Valve Stem Oil Seal *c Gray *d Black NOTE:Pay attention when installing the valve stem oil seals. For example, installing an intake valve stem oil seal onto the exhaust side or installing an exhaust valve stem oil seal onto the intake side can cause installation problems later.
HINT:
The intake valve stem oil seals are gray and the exhaust valve stem oil seals are black.
- Using SST, push in the valve stem oil seals.
*a Correct *b Incorrect - SST: 09201-41020
NOTE:Failure to use SST will cause the valve stem seal to be damaged or improperly seated.
- Apply a light coat of engine oil to new valve stem oil seals.
- INSTALL INTAKE VALVE
- Sufficiently apply engine oil to the tip area of the intake valve shown in the illustration.
*a 30 mm (1.18 in.) or more - Install the intake valve, compression spring and valve spring retainer to the cylinder head sub-assembly.NOTE:
Install the same parts in the same combination to their original locations.
- Using SST and wooden blocks, compress the compression spring and install the 2 valve spring retainer locks.
- SST: 09202-70020
- 09202-00010
- SST: 09202-70020
- Using a plastic hammer, lightly tap the valve stem tip to ensure a proper fit.NOTE:
Be careful not to damage the valve spring retainer.
- Sufficiently apply engine oil to the tip area of the intake valve shown in the illustration.
- INSTALL EXHAUST VALVE
- Sufficiently apply engine oil to the tip area of the exhaust valve shown in the illustration.
*a 30 mm (1.18 in.) or more - Install the exhaust valve, compression spring and valve spring retainer to the cylinder head sub-assembly.NOTE:
Install the same parts in the same combination to their original locations.
- Using SST and wooden blocks, compress the compression spring and install the 2 valve spring retainer locks.
