Technicians:

leaking

Oil

Pressure

Switch

(OPS)

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.
