Information
- The intake camshaft for cylinder bank 5 to 8 has a plastic loss preventer to prevent the high-pressure pump's drive coupling from falling off.
- If for some reason the plastic loss preventer was not installed, the drive coupling would fall off when the camshaft is removed. The high-pressure pump and its drive mechanism will still work even without the plastic loss preventer.
Remove camshafts (according to cylinder bank) -1 and 2-3 and 6- and place on a marked, clean surface. Turn the intake camshaft for cylinder bank 1 to 4 so that it can be lifted up and out of the drive coupling for the vacuum pump
