AIR INLET AND EXHAUST SYSTEM
1. Air inlet pipe. 2. Pipe plug. 3. Mounting flange for the air cleaner. 4. Fitting. 5. Positive crankcase ventilator
valve. 6. Inlet manifolds. 7. Valve cover. 8. Exhaust manifolds.
The air inlet system is on the top side of the engine.
The air cleaner goes on air inlet pipe (1). The air inlet
pipe sends air to both cylinder heads.
The air inlet pipe can not be turned end for end
because the mounting flange for the air cleaner (3) has a
small angle toward the front of the engine. The air inlet
manifolds (6) are made as a part of the cylinder heads.
The air inlet openings and the design of the combustion
chamber give the air needed for complete combustion.
The exhaust system is on each side of the engine.
The
exhaust
manifolds
(8)
are
along
the
outside of the cylinder heads. The exhaust manifold for
the right side of the engine will not go on the left side of
the engine. The exhaust manifold for the left side of the
engine will not go on the right side of the engine.
A positive crankcase ventilator valve (5) goes on
valve cover (7). Valve (5) will return crankcase fumes to
the engine through air inlet pipe (1).
Valve cover (7) can also be put on the other cylinder
head. When valve cover (7) is put on the other cylinder
head, fitting (4) must be exchanged with pipe plug (2) in
the
air
inlet
pipe
(1).
