AIR INLET AND EXHAUST SYSTEM
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).
