Assembly

NOTE:
- Thoroughly clean all parts to be assembled.
- Before installing the parts, apply new engine oil to all sliding and rotating surfaces.
- Replace all gaskets and oil seals with new ones.

1. Install spark plug tubes.
NOTE: When using a new cylinder head, spark plug tubes must be installed.




(a) Apply adhesive to the end of the spark plug tube.
Adhesive: Part No. 08833-00070, THREE BOND 1324 or equivalent.




(b) Using a press, press in a new spark plug tube until there is 42.4 - 43.4 mm (1.669 - 1.709 inch) protruding from the camshaft bearing cap installation surface of the cylinder head.
CAUTION: Avoid pressing a new spark plug tube in too far by measuring the amount of the protrusion while pressing.

2. Install Positive Crankcase Ventilation (PCV) pipes.
NOTE: When using a new cylinder head, PCV pipe must be installed.




Using a wooden block and hammer, tap in a new PCV pipe until its top side is flush with the cylinder head edge.
CAUTION: Be careful not to damage the cylinder head edge.

3. Install valves.



(a) Using Special Service Tool (SST) Valve Stem Oil Seal Replacer # 09201-41020 or equivalent, push in a new oil seal.

CAUTION: Pay close attention when assembling the oil seal for intake and exhaust. Assembling the wrong one may cause a failure.



The intake valve oil seal is light brown and the exhaust valve oil seal is gray.

(b) Install these parts:



(1) Valve.
(2) Spring seat.
(3) Valve spring.
(4) Spring retainer.




(c) Using SST Valve Spring Compressor # 09202-70020 (Attachment # 09202-00010) or equivalent, compress the valve spring and place the 2 keepers around the valve stem.




(d) Using a plastic-faced hammer, lightly tap the valve stem tip to ensure a proper fit.
