Liner Height

[Starlight]

I pulled all the liners and pistons. If the piston was devided into quarters then all the ring gaps would have been inside of one quarter. A couple of them had gaps lined up with each other. 1 piston had the top ring and and the second ring opposite of each other. Very poorly assembled to say the least. Then I cleaned up all the counterbore ledges to inspect and found all of them in mint condition with those tiny grooves that are there from the factory still nicely visible. The liners had the captive brass shims on them and they were obviously a bit worn from movement. The height from the deck to the counterbore ledge was a bit off at 4.7255 avg instead of the standard 4.724 spec. Basically the gasket had burned out because the protrusion too low and not because of fretting. Again very poor on Cummins part. The block surface is in very good shape with no warping or distortion. Block varies .001 thou from the front to the back which I don't think is something to be concerned about.
