Different
compression
in
two
or
more
cylinders
usually
indicates
an
improperly
seated
valve
or
broken
piston
ring

Low
compression
in
cylinders
can
result
from
worn
piston
rings
This
condition
may
usually
be
accompanied
by
excessive
fuel
consumption
TEST
RESULT
If
compression

one
or

is
low
pour
a
small
quantity
of
engine
oil
into
cylinders
through
the
spark

and
retest
com

I
If
adding
oil
increases
the
com
pression
pressure
the
chances
are
that
rings
are
faulty
2
If
pressure
stays
low
probable
cause
is
that
valve
is
sticking
or
seating
improperly
3
If
cylinder
compression
in
any
two
adjacent
cylinders
is
low
and
if
adding

does

there
is
