CAUTION:
• After removing timing chains, do not turn the crankshaft and camshaft separately, or the valves will
strike the pistons.
• When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.
• Apply new engine oil to bolt threads and seat surfaces when installing camshaft sprockets, camshaft
brackets, and crankshaft pulley.

It is not necessary to remove the rocker covers or intake manifold collector to remove or install the timing
