z
If the compression in one or more cylinders is low or the compression difference between
cylinders exceeds the maximum, pour a small amount of clean engine oil into the cylinder
and recheck the compression.
„
If the compression increases, the piston, the piston rings, or cylinder wall may be worn
and overhaul is required.
„
If the compression stays low, a valve may be stuck or improperly seated and overhaul
is required.
„
If two adjacent cylinders indicate low compression pressures, and squirting oil on the
piston does not increase compression, the head gasket may be leaking between
cylinders. Engine oil and/or coolant in the cylinders could result from this condition.
