Engine Covers: Notes
Each cylinder head has a plastic cover for the ignition coil cabling and top of the cylinder head. The covers "push fit" into rubber grommets on the cylinder head covers.
A sound absorption cover for the top of the engine also covers the two Valvetronic motors. This cover is fixed to the intake manifold housing using four bolts.
The cylinder head covers are made from plastic. The retaining sleeves for the ignition coils have molded-on gaskets. The sleeves must be replaced if any hardening or damage is visible on the gaskets. The sleeves are inserted into the cylinder head through the cylinder head cover (No. 1 through 4).
