Richard, no one is contending that the FEL arms do not drop over time. They all do to one extent or another unless some sort of valve like a needle valve is put in line to eliminate the flow of the oil back to the control valve. All we are contending is that the leak down and drop of the FEL arms are not due to leaky piston seals because for that to occur then the rods would have to be pushed into the cylinders, and for that to happen the oil inside the cylinders have to go somewhere.
The place the oil goes is back down the hoses and thru the control valve back into the tank. Or in the event of leaky rod seals that let the oil fall out onto the ground or a leaky hose or leaky connections. In any case the oil must go somewhere, and it CANNOT EVER NEVER NEVER NEVER flow from the cap side past the piston seal and into the space on rod side of the cylinder. That is a physical impossibility no matter how badly the piston seal fits into the bore or even if the piston is present at all.
That is all we are saying..
