WebThe First Puff should be at least 50% of the fifth puff on that cylinder. If the first puff is well over 50% of the final reading, but the final reading is low, that cylinder is likely leaking past the valves. If two adjacent cylinders have low compression it is often caused by a head gasket that is leaking between these two cylinders.
