CHECK INJECTOR COMPENSATION CODE

INSTALL NO. 3 AND NO. 4 CAMSHAFTS

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.
