compression can be lost from a burt valve, bent valve, bad rings, cracked piston, crack piston ring land, sometimes you will notice a loss of compression from a bad head gasket.
with a cyl leak down test you can figure out EXACTLY what is leaking. by simply putting desired cyl at TDC on compression stroke and supplying shop air.
