The ignition system consists of two ECM
controlled ignition amplifier modules, which each
supply four spark plug mounted ignition coils.
The 14 mm spark plugs, one per cylinder, locate
in recesses down the center-line of each cylinder
The on-plug ignition coils are secured to the
camshaft covers. The engine harness connects
the on-plug ignition coils to the ignition amplifiers
located on the vehicle body. A composite cover
fits over the on-plug coils.
The engine is ventilated through a part load and a
full load breather.
The part load breather is a flexible composite
hose connected between the oil separator in B
bank camshaft cover and the induction elbow. A
restrictor in the outlet from the oil separator
prevents reverse flow.
The full load breather is a flexible composite hose
connected between the oil separator in A bank
camshaft cover and the air intake duct.
The ends of the breather hoses incorporate quick
release connectors (see figure, page 36).
The oil separators consist of wire gauze packed
into an open ended enclosure below the breather
