Default RE: Low Compression ???

.002" ring end gap is normal for the DL when new and will no way close up and force the ring out of shape. As Captn mentioned even a .001" end gap would work fine. The pictures of the cylinder look fine from what I can tell but the position of the ring for checking it's end gap on an engine with that much run time is all wrong. In the picture the ring ends are on the exhaust side of the cylinder, the ring endsshould be positioned in the same location and orientation as it is when running, on the intake side of the cylinder and with the antirotation pin relief towards the top of the cylinder. It can make a considerable difference in the measurement especially on an out of round cylinder.
