Computer-implemented methods, computer program products, and computer systems are described for determining cylinder health characteristic in a reciprocating piston engine of the type including a piston-cylinder assembly and a crankshaft. The piston-cylinder assembly includes a cylinder and a piston configured to translate within the cylinder as the crankshaft rotates. In one embodiment, the computer-implemented method includes rotating the crankshaft in a first direction, while generating a first data set comprising a first plurality of piston position measurements and corresponding pressure indicator measurements. The crankshaft is further rotated in a second opposing direction, while a second data set is generated comprising a second plurality of piston position measurements and corresponding pressure indicator measurements. A symmetric aspect between the first and second data sets is then identified and utilized to determining a cylinder health characteristic for the piston-cylinder assembly.
