5. Measure the camshaft journal oil clearance using the following procedure:<\/p>\n

\n

\n
(1)Clean the camshaft journal and the journal receptacle part.<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(2)Put the camshaft on the cylinder head with the rocker arm detached.<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(3)Cut the plastigauge to the same length as the journal width and position it parallel to the camshaft.<\/dd>\n

<\/dd>\n<\/dl>\n
\n
(5)Remove the camshaft caps. (See CYLINDER HEAD DISASSEMBLY (I)<\/a>.)<\/dd>\n
<\/dd>\n<\/dl>\n
\n
(6)Measure the camshaft journal oil clearance.<\/dd>\n

6. Measure the camshaft end play using a dial gauge.<\/p>\n

\n

\n
\n
\u2022 If it exceeds the maximum specification, replace the cylinder head or camshaft.<\/div>\n<\/dd>\n<\/dl>\n\n\n\n
