If all the cylinders have good compression a leak down test is not necessary. If a cylinder or a couple of cylinders had bad compression, a leak down test can provide some answers as to what is probably the problem. If you hear air hissing through the exhaust, then your exhaust valve is not sealing, air hissing through the intake manifold then your intake valve is not sealing and air hissing in the crankcase then the rings are not sealing.
