If a stud bolt is deformed or its threads are damaged, replace it.
Using E6 and E8 "TORX" sockets, install the stud bolts.
| *a | Intake Side of RH | *b | Intake Side of LH |
| *c | Exhaust Side of RH | *d | Exhaust Side of LH |
| *e | Rear Side of RH | *f | Rear Side of LH |
INSTALL NO. 2 STRAIGHT SCREW PLUG
Using a 14 mm hexagon wrench, install 2 new gaskets and the 2 No. 2 straight screw plugs.
INSTALL NO. 1 STRAIGHT SCREW PLUG
Using a 10 mm hexagon wrench, install 4 new gaskets and the 4 No. 1 straight screw plugs.
INSTALL VALVE SPRING SEAT
Install the valve spring seats to the cylinder head.
INSTALL VALVE STEM OIL SEAL
| *1 | Gray |
| *2 | Black |
| *a | Intake Side |
| *b | Exhaust Side |
Apply a light coat of engine oil to new valve stem oil seals.
Note
Pay attention when installing the intake and exhaust valve stem oil seals. For example, installing the intake valve stem oil seal to the exhaust side or installing the exhaust valve stem oil seal to the intake side can cause installation problems later.
Tech Tips
The intake valve oil seals are gray and the exhaust valve oil seals are black.
| *a | CORRECT |
| *b | INCORRECT |
Using SST, push in the oil seals.
Note
Failure to use SST will cause the seal to be damaged or improperly seated.
INSTALL INTAKE VALVE
| *a | 30 mm (1.18 in.) or more |
Apply a sufficient coat of engine oil to the tip area of the intake valve shown in the illustration.
Install the intake valve, inner compression spring and valve spring retainer to the cylinder head.
Note
Install the same parts in the same combination to their original locations.
Using SST, compress the inner compression spring and install the 2 valve spring retainer locks.
Using a plastic-faced hammer, lightly tap the valve stem tip to ensure a proper fit.
Note
Be careful not to damage the retainer.
INSTALL EXHAUST VALVE
| *a | 30 mm (1.18 in.) or more |
Apply a sufficient coat of engine oil to the tip area of the exhaust valve shown in the illustration.
Install the exhaust valve, inner compression spring and valve spring retainer to the cylinder head.
Note
Install the same parts in the same combination to the original locations.
Using SST, compress the inner compression spring and install the 2 valve spring retainer locks.
Using a plastic-faced hammer, lightly tap the valve stem tip to ensure a proper fit.
Note
Be careful not to damage the retainer.
