RE: Liner Height (01-26-2017 )un_yun Wrote: Does raising line hieght help because of a tighter seal on the combustion chamber or because it lowers the compression ratio slightly, thus lowering cylinder pressure? Was thinking about this the other morning @ 3 am. In theory it would lower compression a bit wouldn't it? Which would reduce stress on the internal's and make the engine last longer and able to handle more power. It does neither... What it does, is when the head is installed, it increases the holding pressure between the bottom of the head and the mid-stop in the engine block. This makes the liner significantly "tighter" in its seat so that it is less prone to vibration, fretting, and outer cylinder wall cavitation from the coolant ... I know this video is about cavitation.. but it also shows the cylinder in motion quite well too ... Watch the video at 24 seconds into it. You can see that when the piston fires, it tends to press not only downward, but in the opposite direction of the connecting rod, making it press harder to one side. In an ISX, this is the exhaust side. That is why liner fretting always starts on the exhaust side of the liner.
