TECH TIP
Dealer
Pressure
Technicians:
A
Switch
(OPS)
leaking
may
be
misdiagnosed as a rear main oil seal leak
due to the draining of oil from the
center valley to the back of the engine
and on to the transmission bellhousing.
To avoid potential misdiagnosis, use a
videoscope to identify where the oil leak
is originating. It may take several
minutes
of
idling
the
engine
to
determine the source of the leak.
