CAUTION:
+After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
+When installing chain tensioner, oil seats, or other sliding
parts, lubricate contacting surfaces with new engine oil.
+Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprocket and crankshaft pulley.
+When removing oil pump assembly, remove camshaft
position sensor (PHASE), then remove timing chain from
engine.
+Be careful not to damage sensor edges.
