The intake and exhaust camshafts are located in a separate housing that is screwed to the cylinder head (see illustration 6.0a).
1. Apply a thin, even coat of sealant to the cleaned sealing surfaces (see gray background in illustration 6.0).
When installing, place the casing strictly vertically from top to bottom on the fingers and dowel pins.
2. Tighten the cylinder head bolts in three passes in sequence from 1 to 10 (see illustration).
When performing the 1st pass, the bolts are tightened with a force of 30 Nm.
In the second pass, the bolts are completed by 90° (1/4 turn).
90° (1/4 turn) the bolts are tightened during the 3rd pass.
