Powertrain Engines
Cylinder Head
• The cylinder head is a conventional construction with separate camshaft bearing caps.
• The cylinder head bolts are torque-to-yield bolts, which must be tightened in several
stages (refer to the workshop manual for details).
NOTE: The cylinder head bolts must not be re-used if their length exceeds the specification
(refer to the workshop manual for details).
• The leak-off lines for the fuel injectors are integrated in the cylinder head.
NOTE: Always replace the gaskets of the injector leak-off lines when removing them. As the
leak-off lines are located under the cylinder head cover, fuel leaking from the lines
can contaminate the engine oil. This results in oil dilution and hence in engine
damage.
