1. Exhaust manifold plate
NOTE:
Water is not required for testing.
It is not necessary to pressurize the bottom crank-
case cover nor the magneto cover. There is no pos-
sible water leak path toward the internal compo-
nents of the engine.
Activate pump and pressurize engine cooling sys-
tem to 34 kPa (5 PSI).
Wait 3 minutes and check if pressure drops; if so,
verify all testing components.
– If kit components are not leaking and pressure
drops, verify all external jointed surfaces, tem-
perature sensor and the O-ring between the
spark plug area and the engine cylinder head
cover. If none of these components are leaking,
there is an internal leak and it can be detected
with Bottom End and Top End testing.
Bottom End and Top End
Remove throttle bodies.
Install intake manifold plugs (P/N
529 035 708)
.
1. Intake manifold plugs
Remove the RAVE valves and gaskets.
Install the RAVE valve plates with fasteners from
the kit and tighten adequately.
The O-ring can be checked for leakage with the
valve in place. Simply remove the cover to expose
the parts.
Make sure the spark plugs and the air/fuel rail are
installed and tightened.
