TROUBLE
DIAGNOSIS
OIL
LEAKS
It
is difficult to determine the source of
some
oil
leaks. Even after the
point
of
leakage
has
been
determined, it is hard to tell whether the oil is
leaking past the lip of the seal or past the O.D. of
the seal. Therefore, it is a
good
idea to make sure
the leak is
stopped
by using a nonhardening sealing
compound around the O.D. of the new seal.
