7. Remove camshaft housing cover. Unscrew the 15 hexagon−head bolts M6 and remove the camshaft
housing cover. If this is stuck, it can be loosened by gently tapping with a plastic hammer.
8. Check engine position. The cylinder side which is to be worked on must be positioned to
overlapping TDC so that the camshaft can be removed without tension. For cylinder bank 1 − 3, this
means: the cams of the exhaust and inlet shaft of cylinder 1 point towards each other −Figure 8.1− ,
for cylinder bank 4 − 6: the cams of the exhaust and inlet camshaft of cylinder 4 point away from
eachother (each points towards the cylinder head outer wall) −Figure 8.2− .
