addition, the PCV valve can seal the common chamber
off in case of sudden high pressure in the crankcase.
028RV002
While the engine is running, exhaust fuses and small
amounts of the fuel/air mixture escape past the piston
rings and enter the crankcase. These gases are mixed
with clean air entering through a tube from the air intake
duct.
028RW002
During normal, part-throttle operation, the system is
designed to allow crankcase gases to flow through the
PCV valve into the throttle body to be consumed by
normal combustion.
A plugged valve or PCV hose may cause the following
conditions:
D
Rough idle.
D
Stalling of slow idle speed.
D
Oil leaks.
D
Sludge in the engine.
A leaking PCV hose would cause:
D
Rough idle.
D
Stalling.
D
High idle speed.

Ultrasonic Leak Detector
1. J 41416 Ultrasonic Leak Detector is a
microprocessor-based device used to detect leaks in
the enhanced evaporative emission control system.
The evaporative system is pressurized to 30 inches of
water using the J 41413 EVAP Pressure/Purge
Diagnostic System. Small leaks in the EVAP system
will emit sound at a high frequency undetectable by a
human ear but detectable with the J 41416. The
technician traces along the evaporative system and
can pinpoint leaks due to corroded lines, cracked
hoses, or a damaged EVAP component. The
detector includes a high quality set of headphones to
block out surrounding shop noise and the LED
sensitivity meter allows a visual reference for locating
leaks in conjunction with the audio output heard
through the headphones. Powered by (1) nine volt
battery.
