- Position the intake camshaft bearing cap on the cylinder head.
NOTE:
The intake camshaft bearing caps are legibly labeled from the intake side with E1, E2, E3, E4 and E.
NOTE:
Intake camshaft bearing cap E is a thrust bearing.
- Check the tensile strength of the screws for the bearing caps.
The graphic shows the screw with the tensile strength of 8.8 .
- Check the tensile strength of the screws for the bearing caps.
The graphic shows the screw with the tensile strength of 10.9 .
NOTE:
TECHNICAL INFORMATION
The camshaft is under tension due to the valve springs. Tighten or loosen each screw on the camshaft bearing caps in the prescribed sequence only by half a turn. Repeat procedure.
