Description
Symptoms of a Bad or Failing Crankshaft Seal
The crankshaft seal is the seal located on the front of the engine that seals the end of the crankshaft with the timing cover. Most crankshaft seals are made of rubber and metal and are round in shape. They are usually installed in the front timing cover and seal the end of the crankshaft as it rotates. While they are a relatively simple component, they serve an important purpose in keeping the oil that is constantly being used and tossed by the crankshaft as it rotates from leaking out of the engine’s crankcase. When they fail they can cause leaks which can make a mess, and if left unattended, can put the engine at risk of serious damage. Usually a crankshaft seal will display a few symptoms that can alert the driver that there may be an issue that should be serviced.
High
mileage
If
your
vehicle
is
approaching
high
mileage,
perhaps
upwards
of
one
hundred
thousand
miles,
then
the
crankshaft
seal
may
be
approaching
the
end
of
it’s
recommended
service
life.
All
manufacturers
have
a
recommended
service
interval
for
most
of
the
components
on
a
vehicle.
Servicing
the
crankshaft
seal
according
to
the
recommended
service
interval
can
prevent
the
seal
from
failing
in
the
first
place,
which
can
cause
other
problems.
Oil
leaks
Oil
leaks
are
the
most
common
symptom
of
a
problem
with
the
crankshaft
seal.
If
the
crankshaft
seal
dries
out,
cracks,
or
breaks,
it
can
cause
an
oil
leak.
Small
leaks
can
cause
oil
to
accumulate
on
the
undersides
of
the
engine,
while
larger
ones
may
produce
a
drip
of
oil
from
the
front
of
the
engine.
The crankshaft seal is mounted behind the engine’s main crankshaft pulley, so servicing it requires the removal of the belts and crankshaft pulley and harmonic balancer before it can be accessed. For this reason, if you suspect your crankshaft seal may be leaking or near the end of its service life, have the vehicle inspected by a professional technician, such as one from YourMechanic. They will be able to look over your car and determine if it needs a crankshaft seal replacement.
