CAUTION / NOTICE / HINT
CAUTION:
When replacing an injector assembly (including interchanging injector assemblies between cylinders), common rail assembly, cylinder head, or intake manifold, replace the corresponding injection pipes with a new one.
PROCEDURE
CHECK INJECTOR COMPENSATION CODE
INSTALL NO. 3 CAMSHAFT AND NO. 4 CAMSHAFT
Note
If replacing a camshaft with a new one, make a matchmark on the new camshaft in the same place as the old camshaft. Determine the matchmark placement by using the dot mark as a reference point and counting the number of gear teeth from the dot mark to the matchmark as shown in the illustration.
