REASSEMBLY
HINT:
Thoroughly clean all parts to be assembled.
Before installing the parts, apply new engine oil to all slid-
ing and rotating surfaces.
Replace all gaskets and oil seals with new ones.
1. INSTALL SPARK PLUG TUBES
HINT:
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 in.) protruding from the
camshaft bearing cap installation surface of the cylinder
head.
NOTICE:
Avoid pressing a new spark plug tube in too far by measur-
ing the amount of the protrusion while pressing.
2. INSTALL PCV PIPES
HINT:
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.
NOTICE:
Be careful not to damage the cylinder head edge.
3. INSTALL VALVES
(a) Using SST, push in a new oil seal.
