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.
Press down the intake camshaft bearing cap and hand-tighten screws in the sequence (1) to (10) step-wise.
Join the screws in sequence (1) to (10) in half turns.
Observe the joining torque.

Tighten all screws in the sequence from (1) to (10).
