• Replace the bolts that were tightened with an additional turn after removing them.
• Replace the seal after removal.
• The hydraulic lifters and roller rocker lever are inserted.
• Pay attention to the camshaft housing pairing number and cylinder head. Refer to Figure.

When only one camshaft housing is removed the "TDC" position of the camshaft must be checked when the camshaft housing is installed.

-- Remove the Camshaft Position Sensor 3 -G300-. Refer to CAMSHAFT POSITION SENSOR, REMOVING AND INSTALLING .

• The exhaust camshaft -2- has a flattened side -1-. The flattened side needs to be visible through the installation opening of the corresponding camshaft position sensor in "TDC" position.
